Hi.
Got to use my new Multi purpose Coma Corrector on deep sky objects for the first time tonight, before high cloud killed things.

Corona Australis, 2 x 10 mins ISO 400. Masking technique was used. I
processed 2 versions of the final image, a deeper one,with the inner
nebulosity burnt out and a less deep one to show the inner nebulosity, then
used the masking technique to get the final image. A crop from a bigger
image.

47 Tuc, a 200 sec ISO 200 shot, and 2 x 200 sec ISO 1600 shots, again masked
together, definately a better way of showing 47 tuc as now only the centre
part is burnt out. Its a full frame image, downsized.

10 inch F5.6, MPCC and 300d camera used.

heres the masking technique I used for both images

Its the first time Ive sucessfully used this technique, especially for a globular cluster.
I am most happy with the MPCC, Paul and I, and other MPCC owners with faster scopes (F4.6 to F6) stand to benefit greatly from the banishment of coma :)

They are absolutely stunning Scott,

I really like this technique. It allows so much more detail to be displayed.

Great work.

You have done another wonderful Job Scotty! It was a pity that that high cloud came through last night.

Thanks :)
yes I was going to try for some other globulars but the cloud put paid to that. Tonights not looking good at all.

Looks like the MPCC actually works! I've seen some really bad photo's in mag's that look like the coma corrector did absolutely nothing, but your shots are excellent.
