Andromeda Galaxy, M31..

For me Andromeda is getting out of easy imaging territory (very dark to the east but Exeter is to the west so I don't do LRGB imaging for objects that way) so I'm calling a halt to my efforts for a while... I've done M31 as LRGB - I have some Ha but couldn't face doing it again with Ha in yet, maybe after Christmas, should make it pop so to speak :)

All 2 minute subs:  28x L, 16x Red, 21x Green, 22 Blue so just 6 minutes shy of 2 hours. Taken with a WO Cat 71, ASI2600mm-Pro, iOptron CEM40 Mount controlled by an ASIAir, processed in PixInsight.

I'm not sure what the 'correct' way to display Andromeda is, this way up looked best to me :) Clicking on the image probably gives a slightly clearer version...

I've been tempted to see if I could capture the patch of OIII that's allegedly there and see if any Ha turns up but I think I'll need more Ha for starters as none, or very little is showing on my Ha data outside the galaxy itself..

No! Don't overcook it!

That's M31 as it was intended to be seen. Sometimes an image is presented for science, sometimes for awesomeness of the subject. Here we have the latter :)

 

Thank you :)

I know what you mean about overcooking... that said.. I didn't get as much of the blue stuff come through at each end and I suspect I was over heavy with a mask... if I go back and correct that I may as well add just a smidgeon of Ha... but then I'll over do it.. oh I don't know!!

Lovely image James especially given the relatively short overall exposure time.  On my calibrated monitor there is a hint of green.  You should try to see if you can find Edwin Hubbles Cepheid variable in there.

There is a tint isn't there. Its not on my calibrated laptop, but is on my oh so nearly calibrated desktop... will tweak that after Christmas probably... Hmmm... I'll have a look for Hubbles Cepheid variable.. but only after I've gotten used to my new glasses prescription :)

Cheers, James
