Nice going Martin!
Love the M42 image... looks good at this size at any rate.. (these ol' eyes only noticed 2 motes )
NGC253 and 1365 could do with some more data, but hell, doing all these in one night is a 'very' productive night I'd say!
Martin,
I enjoyed seeing an image of NGC 1365 which is not so deep and not so over-processed that it overemphasizes the other portions of this galaxy (relative to what exists in the real universe)
It is nice to see a more realistic rendition, showing how bright the central region of this galaxy really is.
The way the dust lanes spiral inwards near the center (call it a Mini-spiral) is nicely shown.
There is an extremely powerful burst of star formation (blue supergiants, giant HII regions, etc) near the center of NGC 1365, which is highly obscured by dust in optical imagery, but it does cause the large central rise in this galaxy's surface brightness.
This central "starburst" is well shown in near-infrared images such as this one, which drastically reduce levels of dust extinction:
Nice threesome Mill, especially like ngc253 lots of detail in there ,well done
AL
Thank you Allan
I have more data from other nights so i feel a repro coming up

Thank you Peter
I am using a QHY9m on a ED80 guided with a QHY5 on a finderscope and all mounted on a G11 with Gemini2 loaded with the latest beta firmware.

Thank you Rich
I have more data for NGC253 to play with so i have more processing to do.

Thank you Robert, much appreciated.
I think this galaxy needs a bit more exposure to make it a bit more smoother and it is fairly small for the good old ED80
Nothing wrong with an image that is not very deep;
a lot of the most unusual stuff that goes on in galaxies happens near to the very center of a galaxy, where its surface brightness is highest.....indeed, there are many unusual central phenomena such as Supergiant bursts of OB star formation, active nuclei, large concentrations of cold molecular gas, etc.
These are the easiest sections of galaxies to image, as there is plenty of signal; but obviously, good-to -very good angular resolution is usually required.....for instance, your image of NGC 1097 (at your website) shows the outer outline of its tight centralmost ring of giant star forming regions; but a bit more resolution is probably required to show the ring properly.

Reason: more info
Certainly a busy night. Lots of detail in all the images.
Thank you Paul
One question, what do you think about the colors ?
I adjusted my new led monitor to what i think it is supposed to be but it shows pictures different than my old lcd monitor (this one has a contrast ratio of 5000000:1 it says in the specs).
