the high noise areas.
By splitting the channels -
the blue channel had the most background noise.

Thanks Allan.
I think that I spent a total of about 30min processing the post calibration data after APP did its thing.
Maybe I should spend more time refining the result.
I think that I literally only applied a slight high pass filter from within APP & then tweaked the colour balance a tad.
I'm just lazy, I guess.....

Cheers Marc.
It is difficult to get detail in the spiral arms of this one.
I had to wait to get some reasonable seeing to start to bring out some of the brighter HII regions. I was quite pleased with the detail in the 'companion' NGC1232A as well.

Thanks Mike.
It is quite a challenge to get a decent result on this one from city skies.
Flats have to be pretty good as well as having a good light pollution removal algorithm.
I'm happy with the way that APP does this.
...not sure about the 'real man's galaxy' comment... I do like the occasional beer - but I prefer a good shiraz (I am Italian)

Very nice indeed ....but no mention of the mount?

Thank you Peter..
'tis quite a beast to tame. I wish that GSO would put just a bit more effort into the mechanics of the OTA, because I think that the optics are fundamentally quite OK.
I changed the focuser to a 'NightCrawler', which made a big difference, but keeping collimation can be a chore.
As for the mount; I'm afraid that its just my usual workhorse, the EQ8.
It has proven to be very reliable & acceptably accurate over the past few years. I now us N.I.N.A to control it & with ASTAP plate-solving works a treat.
