Greetings! Newb here, looking to build my first astrophotography scope. I started with buying a used CGEM DX mount, which I will likely send off for a Hypertune.

I still need a tripod and OTA. I had my heart set on a 100-130mm APO triplet refractor, with aspirations of going to 150-180mm using the same mount/tripod down the road.

But the $3k-$5k price is hard to pony up to, and I saw this scope for sale on EBay stating "APO-like" quality with pictures includee in the listing taken with the scope, which looked ok to me.

My question is, would this be a good jumping on point for an OTA, while I put away for the refractor I desire? I plan on using my Canon T3i camera using prime focus.

Just looking for veteran feedback. Thanks in advance for any opinions/expertise.

I have a Stellarvue 115. Also, I have an Ethos 17mm and Nagler 31.

Do you think I need an Ethos 21mm to fill the gap? Or unneccessary?

I have a Stellarvue 115 with Ethos etepieces. Here is a list of my current Lumicon filters:

Comet, Deep Sky, H-Alpha, H-Beta, Minus Violet, OIII, UHC, Variable Polarizer, Planetary Filter Set (4-color)

Would there be a circumstance where I would benefit from picking up an Infrared, or a Single Polarizer filter (non varable)?
what about a Neutral Density filter? I don't expect to be doing a lot of lunar observation, but might do some.

Lastly, would you use something like a multi-filter selector, or how would you go about switching filters?
