The Cygnus Wall in H-Alpha

[AMcD]

I am slowly progressing with dialing in the QHY268M, with the inestimable help of @Richard_, @ollypenrice, @teoria_del_big_bang, @Starflyer and others, to whom I am very grateful.  Last night I managed to get some further data at shorter exposure lengths as part of a test to see if I can address an issue with my star shapes.  This image now represents 9hrs and 50minutes (4 hours 10 mins of 600s frames and 5 hours 40mins of 360 frames) taken through an Antlia 3nm h-alpha filter on a TS 152 achromatic refractor mounted on a Losmandy G11.  The data was captured with SGPro guided with PHD2, stacked in DSS and processed using PS and Starnet.  I am particularly pleased that the camera has managed to split the two stars of what I believe is ES 1451 on the shoulder of the wall.  I am hoping to get some RGB over the next few clear nights (whenever that maybe) and try my first HaRGB image.

Fantastic result! Those stars are looking really good now, I'm glad that the reduced exposure time has killed off those star trails. You have a solid sounding setup, so you just need some clear skies now. I'm looking forward to seeing your final HaRGB image 🙂

I agree that is looking really nice
