Adam_S - Very interested - What is the finder on your FS-102 and how do you have it mounted?
 
Great set-up - Like the Nova Hitch as well - very much.

Hi Pete, it's actually the Lunt 35mm Ha filter which is attached to the Tak clamshell with a single bolt on a Vixen made camera attachment.  The Lunt is light enough that it's very stable.  I center there Tak in white light mode then using the up/down and side/side knobs on the Vixen center the Lunt.  Quick set up and takedown.

Here is my latest set-up.  It is a SV66ED on my Unitron Model 128 Equatorial Mount.

Sure looks like one.  I cut mine back to make it bino-friendly.  The only thing in the picture that gives me pause is the hammer.   :)

Yep, it's a blue tube A-P. Jeff, what you call a hammer is also known as "collimation tool". :grin: I used it to tap the back-plate till square, using a piece of wood which you can also see lying on the floor, and a laser with a center dotted paper mask on the objective. Roland Christen had told me that these oiled triplets aren't completely coma corrected so it is important to get the focuser square to the lens. I think I got it square to within 0.5mm. Doing that first required squaring a Glatter laser - they're very good but mine was off by a tiny bit. Finally, the lens was collimated using a Takahashi collimating scope. Views of Albireo at 320x were out of this world.

It was all done as part of shortening the tube to better accommodate a Mark V and the results are just sweet. I can now use 35mm Ultrascopics without an OCA, framing the double cluster in a mere 50 degree AFOV! With the 3" A-P extension tube, I can use my normal mono eyepieces as well. The extension tube isn't strictly needed but I don't like using the focuser at the end of its range.

I'll post a pic of the shortened tube when I get a decent one.

:bow: I'm always impressed with from-scratch builds. I wish I had the skills. But don't you think the objective looks kind of crumply? :lol:

No, that's an older Mathis gear. I don't have access to a gear hob. It is a great scope, but an F10 achromat has limitations. There is a bit of a halo around stars at high magnification due to the CA. The scope has very nice airy discs. At some point, it would be nice to get a 150mm APO lens for the scope.

The crumply bit is a special adaptive optic.it wigglees around in the wind to correct the incoming wavefront. :lol:

Superb set up Marc. There's always something magic about big refractors on a pedestal ! :waytogo:

Finally got some somewhat clear skies for about an hour plus tonight so I drug out the mount and the ES 152 to check it out. First target was Saturn and it looked pretty darn good without any filters. I ran up to a 2.7x Barlow with an ES 8.8 for 300x. Not mushy at all except the seeing was in and out a lot more. Backed off to a 20mm with the 2.7x and was pretty crisp. Some purple haze but barely noticeable. I put the Baader Fringe Killer in and the image did improve some but not a great deal. It did almost look sharper but I think my mind was telling me things :-)

 

Went to a tight double in Scorpius, the visual double that one component is a very tight double. It split with the ES 8.8 with no barlow. Looked very nice.  Then went over to the double double in Lyra. with the 20mm lens both components were clearly split with no problem.

 

All in all I am a happy camper. The scope has only one detractor, IT IS HEAVY!!  It almost feels heavier than my Celestron 6" f/8. Have to get some scales out.

Just picked up an Astro-Tech AT102EDF.  I've now owned every Kunming United doublet except the big 6" achro.  I think the 4" ED is the best of the bunch.  Doesn't give up much to the 110, but is quite a bit lighter.  Much better light grasp over the 80 and far better color correction than the 102 f11 achro.  It takes power very well and goes plenty wide for sweeping.  A very nice all around scope.
