Messier 1 revisited

[Hughsie]

Returned to M1 over the night of 18/19th January and then again on 20th to capture this small target in Ha, Oiii and Sii. The processing seems to take longer than the imaging what with work in the way so having calibrated the light frames, star aligned and stacked the Ha subs in Pixinsight , I couldn’t resist a sneaky look at what the Ha subs looked like. There is a reflection occurring on the brighter stars and I don’t know if lowering the gain will help with that. Welcome peoples thoughts. Also the background is too dark but I was in a rush to get it done.

40 x 5 mins at gain 139, offset 21 using Zwo Asi1600mm Pro and Baader 7nm Ha filter.

Captured using a William Optics Z103 and SGP.

Hoping to get the Sulphur and Oxygen combined with the Ha over the weekend so long as Mrs H jobs list doesn’t get any longer.

Thank you for checking in.
