I've mainly been using my TV85 for birding and as a guide scope for my EdgeHD11. However, lately I've been doing 2 minute unguided subs for the 11", so I decided to put my Pentax K3ii on the TV85 and try to image the Horsehead and Orion nebulas using 2 minute unguided subs for HH and 1 minute subs for M42. Here are the results.
I used a 0.8x FF/FR with the TV85 and set the K3's ISO to 1600 for the subs (32 for HH and 108 for M42). I think I'll do more imaging with the TV85.
