Hello Stefan,

your images were always top quality, but nothing beats an Infinity 2-1M in experienced hands like yours grin

The whole set is awesome.

Tricolor imaging with an 8'' scope

Hello Richard,

I believe that using the toucam for the RGB portion will be more than enough to obtain great LRGB images. The RGB portion is not of great importance: it is the luminance that gives you detail. Most of the people that do LRGB blur the RGB portion in order to reduce the noise contributions that usually derives from the color channels.

Ciao Richard

Opinions wanted please on the post processing

Hello Floyd,


I believe that CDStack wins this one hands down!

However, I like both images mate wink

Thank you very much Ivan, Floyd and Enrico.

I hope it gets easier with practice, because this hasn't been an easy trip wink

However, I'm still trying to understand why my color channels were so weak: I collected 12 color 10min subs unbinned with an f7 scope and I found myself with very images after averaging them. Using the sum doesn't change things a whole lot, so I'm a little confused.

I guess I'll just try another image sad

Ciao all

Hello,

this is a new attempt: in reality this is not an LRGB, but an RGB with a modified R channel. I followed Robert Gendler's tutorial (to the best of my ability!) and this is the result. The color is certainly better and even star colors are a bit more apparent than in the previous version.

Sooner or later I'll get a good one wink

Ciao all

Very nice image Jim: I agree with Bruce: it looks 3D grin

Very, very nice shot of M81 Jason. Regardless of the little color data the result, thanks to the great processing, is really very pleasing.

Pondering a change....

Posted By Gianluca Valentini
Hello Paul,

I believe that Alan's hint is the most sensible and contains what other have said: mind the seeing conditions at your place. A 10" scope may already be above the limit imposed by the average seeing conditions at your place.

There is also another issue that is a bit more delicate: I don't believe that the mechanical/optical quality of a Celestron scope can measure up to Takahashi's. My first idea would be that, if you want more aperture, go for the Mewlon 300, which is not quite 14" (11.8") but I'm sure it can stand up to any Celestron scope.


Ciao Paul
