Eventually I am starting to get somewhere with this TS Boren replica scope I have dubbed the SuperNewt.

It is lightning fast @F2.8 200mm FL 568mm and even from my average skies is giving me massive advantages over the older MN190 I sold.

Here is 4.5 hours split into

a. 5m unbinned luminance and 2.5min 2xbin RGB all in equal quantities
b. 10 x 10m unbinned 8nm Ha

Imaged with the SuperNewt @F2.8 and QHY9 mono with TS OAG to keep the weight down on a NEQ6 mount.

Hey Cat! Awesome image. I just finished 12 x 5 minutes RGB of IC405 and it's no where near what you have here. I can see I have to add a lot more time to it. Perhaps you could take a minute and explain for me and some of the others what the binning process is about. Unbinned vs 2 x binned etc...

sure,

In laymans terms 2 times binning is combining 4 pixels sqaure into 1 pixel and effectively reducing the x and y dimensions of the image by 2.

This gives you roughly 2 - 3 times the light gathering capability for the same length of exposure, but you loose image scale and resolution.

The normal method for LRGB images is to take unbinned (raw) luminance and then blend in 2xbin for thr RGB channels once it has been upscaled to add a colour layer.

Overall using this method, reduces your imaging time as 2xbin coour you can get away with as the resolution and detail in in the Luminance channel.

You cannot bin on a DSLR btw. It is a CCD method.

Thanks for the explanation, it sounds complicated but most things we do in processing an astro image usually is. The results are fantastic so it must work well.

I really like these ha-rgb compositions, needs lots of efforts to show the beauty of heaven above. Great job, well done!
