Great setup! What is that mount/tripod?

That's an Avalon T-pod, I think it's the 130 (I should know, but I don't).  Edit:  It's the 110.   There are two other sizes the 90 and 110   130 (tripod)

 

The mount itself is a discmount DM-6.  I was told I'd only need the DM4 (cheaper and lighter duty) but insofar as I am very intolerant of mount vibrations I bought "more than was recommended" which is usually a good thing to do.  

 

It's a very fast setup and breakdown, ten minutes each way, and ideal for nights when the forecast or the moon leaves only one or two hours of viewing.

 

But the deluxe viewing is on a GEM.    Here the 92 is riding on top of the GT130, which has its lens cap on, because the scopes take turns on solar.  -GN

Yeah just ring em up you'll have one by the end of the week

 

Over 200 of the little buggers out now, and numbers are apparently climbing. Perhaps 300 all said and done. . . in which case, put out a wanted ad, and I suspect they can be found.

Not so much frustrating as potentially damaging to the optics. I use my scope almost daily, and a few times I have opened the case to find the objective cover has come adrift, which looks like it could allow it to come in contact with and damage the objective in transport.

 

A bit of blue masking tape securing the cover isn’t an elegant solution, but seems to be an adequate temporary  preventative measure until AP acknowledges and fixes the problem. A hoodie are other aftermarket cover is might be permanent solution to consider that doesn’t depend on AP’s timely performance though. 

 

It could be something as simple as the shim stock that AP uses inside the cover taking a set and the cover becomes loose after few weeks of regular use, which could explain why AP isn’t seeing the problem in the shop and hasn’t fixed it yet. Whatever the cause, AP needs to take these reports seriously and fix the cover though. 

Update 11/4/19:

Just received a message from AP saying they have a field installable fix for the loose dust cap that they will ship to me. Suspect that someone at AP monitors CN and spotted my blue tape fix on their $4K scope and barfed :-)

I have had my AT 92mm for several months now, and it is loads of fun. The optics are truly remarkable, the build is solid, and the focuser is very good. You normally would not think of an f/5.5 instrument as a planetary scope, but it performs very well. It excels as a wide-field scope with a 2" 26mm eyepiece. The compact size makes it easy to mount stably and easy to transport to a dark sky site. Finally, the price is right.

My AT-92 has been a game changer for me and has become my small scope of choice for casual back yard fun

My Next lower size scope is my FC-60 and the scope above this one in size is my SW120ED.

Naturally, its the most used of them all because it works great, even with the 2x big barlow in front of the diagonal at 1500FL.
It does everything well, great focuser, outstanding optics, very compact but still very potent for its size.
It sents up quickly using my CG-4, but for all nighters, I prefer it on my new AVX mount so I get help locating objects in my mediocure back yard skies.

Nothing but praise for Astro-Tech for producing this outstanding powerhouse in such a compact package.
