Hi,

Finally I got a clean (for me) M20....the achromatic refractor not so worse to me now.

80mm f/7, CLS filter, 14x2mins.

yes it is much better. you are improving tremendously! however, there is a large dust mote on the left. you could remove it with flat framing. can see lots of structural details on the nebula, almost like a HA image.

Ya, need to do service on the CCD...and take flat next time (always forgot to do this...)
