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.

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
