I took the R6 and Tamron 150-600mm G2 for a test run tonight to see if it would work on the Horsehead.
This is a stack of 15x5sec @f6.3. 600mm ISO @12500. I had it mounted on a iOptron Sky Guider mount and was pretty happy with the results.
I processed the subs through Canons DPP V4 and then aligned and combined them in Nebulosity and then into Topaz AI Clear for the final tweeks.
