SPX350 F4.5, ST10XME, Astrodon filters.
This is a very faint galaxy and needed a lot of stretching out but the addition if Ha has added a little extra. Not as good as RickS rather excellent longer fl image but the outer faint parts are visible and considering I have streetlights behind me I am pleased. The Galaxy is 37 mil lyrs away and not part of any group.
L-5hrs
RGB-45min binx2
Ha-90m.
Thanks, John.

Great shot John. I just finished processing an image of this also. You are right it is very faint. Really a dark site target.
You've done very well there.

John,
I wouldn't have thought it possible to capture that nicely without heading to a dark site. Very well done!
Cheers,
Rick.

Nice work John, came out pretty well :thumbsup: I also used Ha on this one too and I think it helps bring out the HII better in this galaxy..may sound obvious but it doesn't help with all galaxies eg did little for my latest galaxy in Horologium.

A brave effort that has turned out really nice, despite the almost daylight conditions of Brisbane’s night lighting scheme!
Cheers

A great result John.... I scouted this one the other night, only a very dim core appeared on a binned image, so I put it on the backburner for another time.... :) You did very well....

excellent result John - difficult object under perfect conditions, near impossible with streetlights, so you did well.

A good job - did you use an anti-light pollution filter in front
of all the other filters?

Thanks for the comments.
Although I am in the suburbs I am not too deep in the suburbs but do have 2 streetlights about 15 meters away in the West one orange and one low intensity white. My Astrodon RGB filters have a spectral gap in the green blocking out 589nm sodium streetlights which helps with mild light pollution. I think Baader green filters have a similar gap.
