Ha Imaging of the Crescent and Wizard Nebulas




I gave Ha a try again last night--ST-80, MFR 5 II-x, Mallincam DSm, and 7nm Ha filter.  I'm not even close to duplicating some of the Ha images I have seen by others with exactly the same setup!  I can't come close to the contrast and subtle details, and I can't match the pinpoint stars--mine look distinctly more bloated, even with post-processing (I think the focal reducer contributed to the weird halos--and maybe orthogonality issues). 

But I accept the challenge--I'm going to try again tonight and see how things go.

The attached images are my captures--stacks of 10 (Crescent Nebula) and 20 (Wizard Nebula)--45-second integrations.
