Hello!
Till now, I captured this galaxy only with OSC camera. Using RGB filters and the 80mm apo refractor reveals a problem: a color shift in the stars (in their halos)- the red on one side and the blue on the other side. Could be a tilt? But the FR/FF is threaded inside the focuser.
Finally, the frames: L 82x2 minutes; RGB 30x3 minutes each channel, Ha 18x5 minutes. Setup: TS 80mm apo triplet & 0.79xFR/FF; ASI1600MM Pro.
Clear skies!
I too have seen a similar issue as you. Both in my 102mm APO (clamp in FF/FR) and 61mm APO (screw-in). Interested in any response you get on this thread.
Very pretty image sir!
