Rick,

actually the reason why the new version looks sharper is simply that I did
some sharpening in software while the old version was essentially a raw
picture.
I just re-viewed your image of this galaxy and it shows a lot more detail.

I imaged NGC 3310 on January 25 but didn't get enough frames because of
clouds, so I added some more exposures on March 11. NGC 3310 is one of
those objects that are hard to display because the core is so much
brighter than the halo.

Taken from the middle of Berlin with an 8" SCT at f/7, G11 mount, SXV-H9
camera, 42x5 minutes.

Looks a lot sharper than the previous version. Seeing was better too it
appears. Now that I have the problem with my frost gradients cured
(heaters installed anyway), I should retake it but there are so many other
things I've not taken and so few nights (raining for the next week) this
time of year I'll have to move on for now.
