Ah, if coin grew on copse and someone made a 1-1/four” adapter for a spotting telescopic like a Kowa TSN-883, wouldn’t that be fun to push past 80x or 100x? But I digress.

At that place is already John… Encounter postal service 12 at http://www.birdforum…advertizement.php?t=284292

Didn’t went that way considering I’m using now a X95… Promise to give some news to astro users on the next weeks…

The Swaro 95mm is perhaps THE virtually outstanding watch for astronomy employ that birders/hunters can purchase.

I have thought that since the 95mm came out-you confirm my thinking.

I can’t help thinking that members of our customs that only apply their optics at dark are missing out on  a world of delights. The natural world we inhabit is later all function of the universe and the only earth we tin can study in detail. Whether life turns out to exist plentiful on other worlds or a rarity studying it in particular on this planet only makes the nighttime sky seem even vaster and more magical with that noesis. 

It was my TeleVue Pronto that really got me interested in birding and in terrestrial viewing, and then yes, employ them night and day.  In the context of this thread, as Tony said, Astro Scopes make better terrestrial/birding scopes than spotting scopes make astro scopes.

 In my case I volition get farther and say that an higher quality astro scope has terrestrial and birding capabilities that spotting scopes just don’t have.. I am nearly fortunate to have some very nice refractors, if portability is not an effect, no long distance hikes, if whether protection is not an issue (California drought), then I go with the astro scope for birding/terrestrial.

So, yes, I agree, use those optics both night and day.. There’s a lot to see during the solar day and the great thing: Cloudy Skies are OK..

so, bottom line

-it is workable

-some advantages

-more than disadvantages

the place I would see for spotting scopes in astronomy

if for the primary birder with a scope to dapple with the night sky

edj

Agreed.

I recently purchased the Pentax80 angled scope. This is primarily for birding but I went with the larger aperture with astronomy in listen and with the Pentax since it will take 1 1/2″ EPs of my choice. Now I have to look until next autumn to test on the Pleides.

Thanks, David. In my researching I did come across this and also a thread here on CN mentioning this adapter available from Spain. Nonetheless, ii things stopped me from going down this path. First of all, I thought it would exist risky (and foolish) to buy the expensive Kowa fluorite lookout just to meet how much I could push button the ability, especially since I haven’t even played around with my new Pentax eighty yet. And secondly, it’due south about the southward/w and not the h/due west, I similar to remind myself. Significant, information technology’s better to use what you have (or just got), than information technology is to get “meliorate prepared” past getting better gear. Ane mail I came across recently asked is information technology better to spend a couple of grand on (fill up in the blank) or to spend information technology on, for example, a trip to Costa Rica to do some birding. Hummm.

So in that location is a limit to the lengths that my rationalization will take me, thankfully.

Thanks,

John

Jon, I completely agree with you lot about quality astro scopes being able to become where spotters can’t, weatherproofing notwithstanding.

Concluding August I was fortunate enough to visit the Big Isle (Hawaii) with my family unit. I took my 13″ long Heaven 90II along with an Extender Q and it provided wonderful views one night right outside Volcano National Park. Erstwhile later, from a great balcony (AirBnB) I had a wonderful view of Kailua Kona harbor. They were having a angling tournament and I was able to attach a RACI prism and I call up getting decent images of fishing boats using a Tak 5mm LE eyepiece. Can’t recall if I used the 1.6x extender but I’d bet that the Sky 90II would take you to magnification levels that spotters would accept difficulty reaching.

The good news is that in that location’southward more than ane mode to skin a cat. And that “just doin’ it” is the best role.

Cheers,

John

Hither is my two spotters side by side.  Kowa is fastened to Takahashi clam shell band.

Longer one (Takahashi FC100DL f/9) yields 51x-102x with Leica ASPH Zoom eyepiece.

Shorter i (Kowa TSN-883) yields 40x-96x with Kowa TE-11WZ zoom eyepiece and 1.6x extender.

Both produce excellent lunar/planet image.

I tested Kowa at loftier power 270x.  Information technology produces fantabulous star image.  I was very surprised.

Every bit y’all see below, it is awkward to employ
:)

I take three copies of Swarovski ATX 95 objective modules.  None comes close to the Kowa at high power.

I use my inexpensive Leica 77mm not APO for both day and dark.  Surprisingly I do not see any differences comparison it to Swarovski Hard disk 80mm telescopic at night.

Given  the quality of both instruments,

   I believe that both would be more limited by the atmosphere than by the telescope.

The limitations of the instrument would be nearly 5-10 times worse looking through daytime air

horizontally than looking through  might-time air vertically.

Tammy, that is using the EMS with the objective module, right?

Somewhen, and presently, the best high power astro utilize of the ATX 95 would be using the TLS APO with the ocular module and than i astro eyepiece. Don’t know if it would work well since never tested – reverse image isn’t useful for my CR-birding…

How would y’all rate the Kowa high power performance compared to the TMB92?

Hi David,

Yes, high ability test was with Swarovski ATX 95 objective modules with EMS visual back.

Visual use with TLS APO module  and ATX 95 spotting telescopic is just as uncomfortable/awkward as Kowa with photo adapter (Barlow).

Information technology isn’t applied.  It is just a examination thing not real utilize.

I would say Kowa TSN-883 is every bit adept as TMB 92SS if your application is 25x-96x range.

I matter though, TMB 92SS can take 3″ eyepiece but non Kowa

the nikon fieldscope serial take an excellent zoom ep from 25-75x, its very capable for astro on their 80mm+ scopes.

the other 2 to wait for & utilize are the celestron regal & pentax scopes, reason being they both take 1.25″ ep’s..the regal 100 is very well priced

the Alspha spotters accept the add-on of using the 25-50x zoom, very wide fields & excellent eyes, leica zoom..grab an adpater for it & away you get

I’ve used the Nikon 82mm ED f/five angled spotting scope with Nikon 20x, 30x, 38x, 50x, & 75x Wide Field eyepieces (60-70 degree AFOV) with splendid results on dark skies.  75x on Saturns rings show abrupt edges betwixt gaps.  I’ve besides had superb results with my Zeiss 85mm angled Diascope (Flourite lens), but the eyepieces are expensive.  I think they are both sharper than my 1960 Japanese 80mm f/15 refractor I had when I was a teenager back then, simply those former eyepieces were zilch like our modernistic ones.

If you lot look at the size and weight of the short astro above,

  the trade-offs are clear:

—it is much heavier and larger, to reach a wide view at depression power

    and, at the same fourth dimension, a college practical tiptop power.

—the tripod besides has to be a lot heavier, due to the top power, and the mass of the telescope/EP

—the total price can exist very high.

Hey all,

Newbie hither and following this thread with bully involvement.

I apply a Swaro ATS 80 and a Zeiss Diascope 85 for astro viewing at nights and birding/wild fauna on days. At to the lowest degree one of these scopes is most always with me when I’g abroad from abode as a quick grab n get if opportunities present themselves. I do a fair bit of bushwalking then a most of these times a scope is with me in my backpack and tripod is strapped to the side of the pack. I use these spotters on a Carbon fibre tripod with a standard pan/tilt fluid caput and find that setup perfectly suitable for the blazon of viewing I like to practice. the fluid caput dampens vibrations very speedily. The 45* bending doesn’t stage me. If I’m looking at something towards zenith, I but extend the scope higher (or I sit lower) then the eyepiece is at a comfy position for me to view through. I besides adopt the waterproofing and ruggedized casing the spotting scopes have. My kids can handle them, I can utilize them in rain, dry out dusty, and humid environments.


_DSC0119_zps68m2ilpu.jpg

I purchased an 80mm APO triplet (Orion ED80T CF) for the same purpose, however packing the scope + diagonal + 2 to 3 eyepieces was equally bulky and so the 80mm currently doesn’t get used much and sits in its pelican example.

Its proficient for car camping or doing a browsing session at domicile, but not a true grab n go (past my definition). The other affair was that going to a 5mm eyepiece, I still only got 96x magnification so not much different from the 75x I’m getting from the Zeiss. I know I can use a Barlow to go higher, and I should probably buy i, simply haven’t done then yet.


DSCN7330_zpst30cpos3.jpg

Sympathise my setup may not suit everyone, but it works really for me every bit i dont have to worry about changing eyepieces, beingness delicate with the scope etc and I just become a lot of enjoyment out of pulling the telescopic from my backpack or car, locking information technology onto the tripod and start scanning the skies.

I’ve got ii” adapters coming to allow me to employ the Zeiss and Swaro eyepieces on telescopes so that volition be interesting as I’ve read a lot of positive reviews regarding the these zoom eyepieces.

cheers

Makes sense either way.

Affair is, a lot more power and you’d exist waiting longer for the

  atmosphere to cooperate and craving a 6-12 inch aperture for brightness.

Even when you spend a lot, in that location are real limits.

It’s worth information technology to hike a smaller scope upward  a few thousand anxiety or more!

I use the Pentax 65ED II straight scout for birding and astronomy.  I find it quite nice up to around 78x or so for astronomy, lite and easy, plus of course a fantastic daytime telescopic and it is water proof so no worries about using when raining in the field.  I also use Pentax XWs with it.  A bang-up fun travel scope and picket that is plenty satisfying when on trips.  So that an some 8×42 binos cover all my travel needs every bit astroing is non the main purpose of my vacations simply like to take adequate capability on manus for some evening diversions or daytime spotting.  Once in a while I will take an 80mm f/half-dozen on a holiday, just information technology is a lot more effort as it needs a mount instead of a simple photo tripod and just a bigger more complicated affair with diagonals and all.  The Pentax 65 ED II uses my light camera tripod so nil extra from the photographic camera gear to bring.  Convenient and fun.

Here is my two spotters adjacent.  Kowa is attached to Takahashi mollusk shell ring.

Longer one (Takahashi FC100DL f/9) yields 51x-102x with Leica ASPH Zoom eyepiece.

Shorter one (Kowa TSN-883) yields 40x-96x with Kowa TE-11WZ zoom eyepiece and one.6x extender.

Thanks John, been browsing for a while and exchanging some individual messages simply time for me to spruik upwardly 🙂

TAMMY – practiced feedback on the Kowa. Was the image notwithstanding quite brilliant? I’m surprised you achieved focus with that setup? Accept you got much focus travel left across getting a sharp image?

On the Zeiss I cant focus to infinity with my XW’s every bit at that place’s not plenty focus travel. I can but become out to effectually 200m earlier hitting the focus stop.

I’ve been brash to try Plossl’s or finding eyepieces with no lens in the barrel (and subsequently removing the barrel) to allow the eyepiece to sit closer to the prism on the spotting scope every bit a potential solution. Would be interesting to push the Zeiss beyond its electric current 75x.

Hi John,

Yes, the Kowa has first-class optics and very compact for the aperture 88mm.

It is adapter for camera to use Kowa spotting telescopic every bit 680-1000mm telephoto lens,

kind of zoom Barlow lens with T2 connectedness.  When you apply it visually, view is upside downward
:)

TAMMY – good feedback on the Kowa. Was the image still quite bright? I’m surprised you achieved focus with that setup? Have yous got much focus travel left beyond getting a sharp paradigm?

How-do-you-do Jeelan,

I place Baader 1.25″ Clicklock eyepiece adapter on T2 male person thread of the photo adapter.

You lot can accomplish focus to infinity easily with the adapter.  Just every bit I mentioned above, it isn’t for terrestrial utilize, I mean upside down.

For image brightness, it just depends on what focal length of eyepiece yous option
:)

I tested a few short focal length eyepieces (Ethos SX 3.7mm,  Takahashi LE 3.6mm, Pentax XO 2.58, Nagler ii.5mm, Vixen 2.4mm, yielding 270x-416x), paradigm even so remains very sharp.  It shows how well the spotting scope is made.  Aye, prototype is not so bright at the power

Hi all,

I as well employ the Swarovski ATX 95 for both terrestrial and astro use, and take tested multiple samples of all the premium spotters on the market over the final 20 years or so. My two cents:

– With spotters perhaps more with astro refractors, one must brace oneself for sample variation. Since spotters are intended for use at exit pupils of over i mm, fifty-fifty height-line manufacturers have been allowing poorer quality with respect to aberrations than what would be considered acceptable for astro scopes. It hasn’t helped that for 45 degree angled scopes almost manufacturers (Nikon Fieldscopes is a notable exception) have been using a prism pattern (Schmidt) that requires very high manufacturing precision to not degrade the star images at high magnifications. Fortunately, things have been improving over the last v-10 years, and nowadays skillful samples of Kowa 883, Swaro ATX, Nikon Fieldscope or EDG or Zeiss Diascope can have essentially diffraction-express optics. My Swarovski does, and I have seen several others that practise. Mediocre or poor specimen are notwithstanding quite mutual, though, and then you actually demand to try before you buy or to take generous return policies if you purchase untested.

– Since the best samples I accept tested of both the ATX 95 and the Kowa 883 have had well-nigh perfect optics, their relative difference in resolving ability has come downward to aperture, where the ATX wins past 8%. In addition, the ATX has significantly better lite transmission, which readily shows in terrestrial employ in low light.

– Kowa 883 has the 1,6x extender, which is fabulously good. In addition, it is possible to stack more than than one extender on it. I have briefly tried it with 2 extenders back to back, and the prototype held upwards beautifully. This mode you lot go to 154x. This combination looks like the one in Tammy’s meridian photograph, except that there are ii of the extenders instead of 1. The philharmonic is just as great and solid equally with one. In principle, you lot can keep adding them until you run out of money, infinite or light throughput.

– With the ATX 95, for astro use and sometimes for difficult distant bird ID’south in expert seeing, I employ a Zeiss 3×12 monocular stuck into the eyecup every bit a booster. This way, you lot go 72-216x, merely since the Zeiss 3×12 does not have particularly excellent multi coatings and adds quite a flake of glass to the light path, you lose a fair bit of brightness and contrast. Field of view gets very narrow also, only resolving power is very proficient.

– With any of these 45 caste spotters, fashioning a elementary aiming device effectually the objective end or using a red-dot sighter helps immensely.
