Crazy good M51! be proud:)

Yes the CLS filter is always on now, it goes CCD/CLS/filter wheel/OAG/MPCC.

I've been thinking about adding mine to the mix for the mono camera too, but dont really fancy wasting clear sky time testing between the two options, clear nights being rare as they are. With the fov offered by the C11 gradients from LP aren't too bad, but i'm using a Skywatcher Esprit 150ED at the moment and that gives a lot more sky to think about.

Have you got any convincing results one way or t'other with/without the CLS Mike?

Cheers

Here is M33's core with CLS/RGB (note there is no Ha data for this image) I am not sure if it is just with the HX916 but the extra long R subs required to get the G2v weights the same really upped the Ha response of the RGB data.

M51 will be the test that I will have both types of RGB data to compare.

Just managed to grab a single 10 second sub for each RGB filter with the CLS in line on a G2v star between the clouds.

It looks like I will lose the Ha advantage the hx916 AND G2V/CLS imaging gave me .

The ratio comes out

R = 1.38

G = 1

B = 1.37

wow @ M51 in color! 0_0

Simply gorgeous image. I hope to have first light with my new Atik 314L on Tuesday and this is my target! I am just going for bucket loads of Ha

Here is some old colour added in the mean time.

About 25 million years old !

Brilliant work!

Lovely image Mike - interesting to read about you using a CLS filter in line with your filter wheel - I've just added an IDAS LPS to mine (but I haven't seen any clear sky since to test it out). Also - another vote for using a DMK21 as a guide camera - it's never failed to find a convenient star yet..and of course it's dual use.

Wow, that's a good M51 there Mike, looking at your web site I see you have shot this galaxy a few times over recent years but this Lum set looks to be the start of your best shot yet.

That is a stunning M51 simply superb

Well that ratio did not work (must have been shooting through thin cloud).

After running a new set of calibration frames on a clear night i shot some new RGB that gave me this ( details here)

Well done Mike. Super pic.

Beautiful colour and detail - great

Stunning! Love the colour one
