I too have the new GTF 102 and still waiting for first light, maybe sometime in the next century or so I'm not holding my breath. I also own an older Zenithstar 80FD and let me say the crayford focuser is a piece of *BLEEP* and that's from first hand experience. But as I've said before the 2.5" R&P focuser seems to be a huge improvement but only time will tell. For now I'm very happy and WO isn't the only scope company out there to have a bad focuser good god look at Orion, Meade and Celestron.

I'm so down on WO that I bought a new WO Z71 APO last night and will have it the first of next week. So now I have four new scopes and two new mounts that haven't seen first light. If ever I get a clear weekend I've got my 50MP Hasselblad ready to go to work.

Thanks for all the compliments on the scope.

Kon - you are being a troll with your comments, please stop. I you don't have something constructive to add, or can recommend a technique that I can use for testing the focuser to see if it behaved like yours did, then please start your own thread and you can bash away.

SteveG - Thanks for the compliments on the scope, but I think you might have me confused with someone else, as I didn't mention a tripod.

And to everyone else - hang in there, I will test the scope and write a review. Hopefully this snow will be shortlived and I can get outside for some observing soon. I think this 5-7 inches of snow hitting our area is entirely my fault, since there is usually a direct correlation of bad weather to new astro gear.

Timm, I was about to buy a WO FLT110 when the Tak came up. I looked through some WO scopes and was very impressed. Looking forward to your review of this beauty.

I thought you mentioned it in another thread - Oberwerk Surveyoys tripod blems. I'm a huge fan of surveyors tripods, and the blem's at $120 is a bargain!

Hi Steve - wasn't me, but thanks for the link. It looks nearly identical to the tripod on my WO EZ Touch mount, and would likely be a good match if I need to replace a leg, or something.

Timm,

Congratulations on your beautiful new telescope.

I look forward to your report on that beauty. And I am celebrating your wonderful new WO.

Have fun.

Best, Linda B.

William Optics certainly bring some colour to astronomy with their trim finishes, a far cry from the black n white of old.

Hi all,

One important thing to consider if you are interested in this design is that it is set up for astrophotography as the primary goal. The picture of the moon I took was with a WO 2" photo adapter, T-Ring connected to a Canon 60D with perfect focus, meaning I didn't have to rack the focuser all the way out. Because it is designed to not have to add extra extensions for photo use, it also means that you will be at the very inside limit of the focuser with a 2" diagonal for visual use with eyepieces. I found that my WO SPL eyepieces would not quite reach focus with the 2" diagonal, but the UWANs and 2" WO SWAN would. Using the 1.25" diagonal and all of the 1.25" eyepieces were fine. I knew the WO zoom would need the 1.25" diagonal, as that eyepiece also requires more inward focus.

Not really an issue, in my opinion, but certainly something to note, as its quite possible that other eyepieces would require the use of a 1.25" diagonal.

Once I can get more testing in I will let everyone know, and hopefully I will be able to let the scope cool down and do a really good star test. Because of the flattener, in the middle (right where you see the red ring in the middle) there is a large area of air that will require more time to cool before it will settle down, especially considering the current large difference between the inside temp and outside temp this time of year.

Timm

Good info. Thanks. I bought mine with a 80/20 split (AP/Visual) in mind. I'll do most of my visual after an AP session while I shoot darks.

I use the 60Da for AP. I've been needing to pick up a 2" adapter. Guess I will order one this weekend.

Oooh a 60Da -

Post pics if you have any - would love to see your setup.

WO has a nice 2" photo adapter but any will work, I think.

I would love to hear what mounts people are using for AP with this scope or in general.

Timm

Your to kind.

I have a couple of wide field images on Flikr. I also have 1 pic of the 60Da on my C8. I think its the night I imaged M81 and M82 (which are on AstroBin)

Astrobin:

With the exception of M16 and M8 everything was shot with the 60Da.

I was thinking about one of these:

I may just go with the WO. I hate the thought of ordering something and it not working. Being that I can't just run to the store and buy what I need and all.

I use the Orion Atlas. Rock solid. When doing research it felt like the Atlas was the best/most mount in its class. Combined with the Orion SSAG and 50mm guide scope I almost never have issues. Almost because I do make mistakes

Excellent pics! The photo adapter looks like a great idea.

The Atlas looks like a good choice, thanks for the info.

I want to test the focuser with different loads, or weights, to see how much it can handle.

Does anyone have some suggestions for weights?

My Canon 60D with the 2" photo adapter and T-ring weighs about 1Kg or 2.25lbs so I'll start with that, but what's the most weight I should test it with?

Thanks!

Timm

I was able to get in some viewing tonight. It was very cold outside, about 20 degrees F, and the wind chill was about 11, so I only stayed out an hour.

I was able to star test on Sirius though, and it is as perfect of a star test as my eyes can determine.

Not only that, but based on what I can see, the field of view is very flat. While this scope is designed for AP use, I can say without question that it makes an amazing visual scope as well.

Clear skies,

Timm

Nice report, Timm! Glad to hear that your new scope is working out so well for you.
