M83 (Southern Pinwheel)

[Geoff45]

Taken from Wiruna on Tuesday with f/7 110 mm refractor, 4 x 5 min each RGB, 8 x 5min L for a total of 100min. Camera is QSI 540. More data would be nice and I was going to collect some more yesterday, but sky murked over with thin cloud about 1am. Had some trouble finding a guide star with the OAG, so had to crop to centre target. Field is about 25' x 25'

This begs the question... are there any galaxies or nebula that you can see colour in with the naked eye alone?

Great work, super detail and colour :thumbsup:
Hope the skies are clear for SPSP :prey:

Very nice image. Your polar alignment was a bit off though and you have a bit of rotation plus a bit of sag there at the bottom right. Minor though and does not detract from a wonderful image.

Looks very nice Geoff, sharp and good colours :thumbsup:

Good points Greg. The sag (or perhaps focuser not square-on) is something that has been bugging me for a while. The other problem is that I had trouble finding a guide star (with Orion SSAG in off-axis guider mode) so the original image is way off centre frame and had to be cropped, so we are looking at the off=axis region here.
