Re: Mosaic processing

I haven't done a lot of mosaics either, but I already encountered the problem with the monochrome outcome when processing a M31 mosaic (https://forum.startools.org/viewtopic.php?f=11&t=2329). The reason was that I opened via the 'open' option with the data source being OSC. This results in a monochr...

Re: Messier 106 et al.

Very nice image, Dietmar! I especially like the color balance you achieved :bow-yellow: And NGC 4217 also looks great. Impressive for not even four hours. I once tried M 106 and aquired more than five hours but struggled. Bright moon might have had something to do with that. AndyBooth Really nice M ...

Re: StarTools 1.9 Beta

Hi Steve, dunno where it comes from, but as a workaround you can try to undo the damage in the affected stars by selecting them in mask and use the 'undo fg' in the Layer module. Or blur them in the Layer module (which also can be done with an already finished image). BTW: This appears to be a stars...

Re: Yes, another M42, it is this time of year....

Hi Freddy, looks very good in my eyes given the conditions. I also can't see a big deal of mottling although the screen I am working with currently basically hides most of the shadows so... In terms of color I think it is really well handled given that it's duoband. The color in my image mainly come...

Re: OK, so a Tadpoles Startools version - SHO color palet -IC 410

Hi Freddy, this is what I came up with: IC410_Freddy.jpg Disclaimer: I have absolutely no experience in processing mono/SHO data sets nor data coming from refractors. My first thought was: "Where are the spikes"... This is a pretty straight forward processing. No fancy stuff. SHO matrix was one of t...

Re: M 42

*Addendum* Regarding star shape / diffraction patterns: In some stars one can also see chromatic aberration. I am pretty sure that's also caused be the low alt. M 42 doesn't rise higher than 35° for me... So maybe not the best data set to judge the optics.

Regards
Stefan

Re: M 42

Thanks, Mike! I was watching the satellite loop and it appeared things were clearing out for the night, with the clouds all starting to pass to my north, heading southeast. That opens up Orion just fine. I took the mount outside and plopped it down on its marks, but looked up and saw clouds to my no...

M 42

We got one more clear night here. And which winter target can be finished in one night? Right, the Orion Nebula: https://cdn.astrobin.com/thumbs/hKa3C3kqi_Ny_16536x0_ieTZ0INm.jpg See https://www.astrobin.com/qe320u/ for technical details. Actually I collected some 10 sec shots for the core but didn'...

Re: M 78

Thanks for your feedback, guys. Tried to reply earlier but yesterday the forum was down I guess. In terms of ringing that may be SVD but in some cases it was probably me being pretty heavy handed on shrink as usual. I also collected some data on M 42. There I have quite some issues regarding rings a...
