Yes long time no post, has been deliberate as I tame my 10 inch F4 and ASI1600 combo. Finally the spacing is getting closer to right, and tilt pretty minor.
I took 240 shots of 60 secs 2 nights ago, very windy and 3/4 bright moon up above testing the 3nm Ha Astrodon filter. So I culled the subs to the best 77, boy does being ruthless with subs help the sharpness! Thanks to PI's subframe selector tool for that, and a last minute blink.
All taken at -15c and 139 gain. Will be interested to see how much more contrast I can get on a moonless, still night.
This is just a basic stack, DBE and slight noise reduction, but later I started experimenting with the new "LocalFuzzyHistogramHyperbolization " script that look very effective, if used in a layered and subtle way. For those interested, below is a video of the changes in appearance based on using the different main functions. I haven't found a decent tutorial yet, would love to know of one if you''ve seen any about.
anyway, I hope the result looks promising to you, it does to me! I think I"m set for imaging bits of the sky at 1000mm, .75 arcsecs per pixel, for ooh, a good 15yrs.
