This is my first attempt at something with my new filter ( STC Duo )
I’m pretty happy with the results although I wished I’d imaged it at ISO 400 and hadn’t been greedy and gone for 800. It would have given me better star colour because of better dynamic range. I’ve already learnt this about my camera and yet I got greedy anyway.
Apart from that I’m happy. The details are as follows ;
25 x 300sec subs at iso 800 on astromodded Canon 350d
Heq5 pro mount with Nextguide guiding
Vixen R130sf Newtonian
Badder MPCC
STC Duo Filter
It is a great image Ryan so dont punish yourself and take time to appreciate how good it is...I think looking at all that has been done right beats super critical analysis...even gods do not achieve perfection.

Thank you Alex. Don’t get me wrong, I’m stoked with the image in general, there’s just a few bits and pieces I knew I should have done to make it better. Clear skies again tonight so I’m going to have another crack at something.
Thank you Chris. It’s a cracker of a filter isn’t it ?
That’s a really good M8 Ryan under light polluted city skies
I think ISO 800 is the sweet spot for most Canons. My 600D works best on ISO800
Your getting very good results with your gear under light polluted skies
Well done !
Correct me if im wrong, but I think you might have some difficulty capturing star colour with a narrowband filter or agressive light pollution filters. It may be worth not using the filter, and shorter subs, to capture the stars without over exposing them and editing them into the capture with the Light pollution filter exposing the nebula. It would take a fair bit of extra work though.
The filter actually produces reasonable star colour Nathan. It picks out rgb quite well with it's narrowish bands. At least that's how I find it when I process as a simple colour image. I've even captured a few globular clusters in between other stuff just to see what's it like. They are okay, but that's not it's intended purpose.

Thank you Martin,
When people talk about the sweet spot it’s normally to do with SNR. As far as that goes, 800 is right on my 350d as well. There’s a pretty linear drop between 800 and 400 but from my experience there’s big gains in dynamic range. Certainly on my modified one anyway.

You could be right Nathan. This is my first outing with this filter. Although I notice Chris disagrees and he’s had the STC for a lot longer than I have. I’m going out again in the next couple of nights so we’ll see what happens then.
Great job with the nebulosity and background Ryan.
You've should be happy with that.
Experiment with different exposure times on clusters (30, 60, 120, 180 secs) at ISO800 to see what happens with star colours. It's a bit more work, but colourful star fields blended with the nebulosity can be lots of fun and quite satisfying.

What software have you used to process?

Thank you Jeff. I’ll give that a go next time the cloud predictions don’t lie to me lol.
I’m using DSS for stacking then Photoshop CC which I feel I’m really starting to get the hang of.
