Not being in the middle of Berlin has some advantages in astro
photography! I can't even fathom how you do so well from there. What
is your limiting magnitude at the zenith?

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.
