Re: Andromeda Galaxy, M31

Yeah, think I meant bigger scopes need better tracking/guiding or some such thing; smaller is more forgiving?

All SNR in the end, no matter the scope!

Re: Rosette Nebula HOO ;-)

Thanks for the flow Dietmar. A big fan of the evolving SVD module and process all my images with sampling; rare to go back to synthetic decon.

I'm curious of everyone's thoughts on the Spatial Error "e" option within SVD. Not sure what this entails but I get better results on stars using it.

Re: Andromeda Galaxy, M31

Thanks Mike; yes, really liked your M31 and the way you framed it. :thumbsup: Its the choice you make when buying a scope; going for small wide field aperture (great for large targets) or big narrow field aperture for galaxies; many people have both (or more!); I use 81mm/382mm and 51mm/250mm scopes...

HOO and H(H+O)O renditions of the popular video game character from 1980; yes, I played it back then!

Andromeda Galaxy, M31

Took a leap of faith using just a UV-IR cut filter from Bortle 8 skies but M31 was placed close to the zenith so away from the city light dome; turned out better than I expected. 11hrs 50m total integration across four nights in September.

Re: Rosette Nebula HOO ;-)

Very nice Dietmar! The Rosette does provide a better OIII amount than some other emission targets and you captured it well here. :thumbsup: Did you run the 2nd Color iteration right after the first or wait until tracking was off after denoise? Did a good job on the blue halos; will try that. I agree...

Re: IC 1805 Heart Nebula, HOO RGB

Good points Mike and yes, have dragged sliders all over the place in Color (and other modules) to see how I can change the balance, including Scientific and Artistic modes; even played around in Filter and Entropy with interesting results; default mask though. A matter of give-and-take unless you st...

Re: Rosette Nebula HOO

Hi Justin, Nicely done with the Rosette, looks great! Welcome to the Duo-band Bi-Color group! It so happens I posted a similar thread last week with my Heart Nebula and have been going back-and-forth with Mike in Rancho on processing tips; very much a matter of taste on how far you push Ha and OIII....

Re: IC 1805 Heart Nebula, HOO RGB

Nice SHO image Mike! Love the soft coloring; assume with mono CAM and individual filters? :thumbsup: Yes, I often use Shrink with 0 iterations and DR to 1.1; works great to get rid of ringing. I`m not a fan of driving stars into tiny dots; they come in all shapes and sizes so like to showcase them, ...

Re: IC 1805 Heart Nebula, HOO RGB

Re-processed in 1.9541 alpha with exact flow/settings except in Color module, did not touch Ha, OIII sliders to get the default Bi-Color result with my setup and location; simply adjusted Dark/Bright/Saturation sliders to taste. I did have to crank the Deringing in SVD to 75% as well as set deringin...
