Hi David,
That's a really nice composition with pleasant colour and contrast. We especially like the golden bit of milky way below the Lagoon. Beach sand, perhaps.
Thanks Rick. I still have the example image from last years tutorial in Sydney. Might need to do a spot check against that..

I don't do darks (or bias) either with my SX H694 camera, just dither and median combine - easy huh?
Mike
Aah, now then...real men just dither and bias with uncooled DSLR,s.
It does help though that's it's a pretty bright object with shedloads of background stars. I have the area around M87 as well but there just wasn't enough data compared to this so it's as noisy as a campanologist,s busmans holiday. By te way, thanks for the comments!

Thank you very much, MnT. I seem to recall there is some pretty faint ha around there so yup, subtle.very beach indeed.
Really well done Dave and nicely processed! Nuanced and pleasing colour balance plus good depth showing the fainter neb throughout the frame and around the borders of both objects.
Really nice David, far better framed than mine, better framed than both my M8 & M20
The high res looks good too.
I have found that with my DSLRs I need darks to help with a little bit of amp glow. It isn't TOO bad but it is difficult to remove without darks. The D700 had some strange banding that I cannot get rid of without matching darks, the D7200 has amp glow and I haven't actually stacked anything un-calibrated from the D810.
I just take my darks while I am packing up the telescope so I can get a number of them easily enough.

THanks Markus, glad you like the processing and thanks for commenting.

Really interested to see what you do with the 810..Carolyn has this camera and won't let me anywhere near it..it's really very good. Leaving out the anti alias filter and the fact it's their highest res DSLR could make quite an impact
There's a canon banding script in PI that you might look at. I also found using super bias was helpful as well, though no idea why that would be.
Grouse going there David, the blue around the triffid is showing up really well too
Great processing done considering the thick star field, and the variety of fainter dust structures are well brought out for 5 min subs
The joys of dark skies huh
Gotts'ta be very happy with that beauty !!
Missed than one. Nice fov with great details. Colors are spot on too. Just need to be mirrored.
Dang..Spotted! Have corrected geometry on the thumbnail. Weird as the individual subs were fine. Must be something in the way this got stacked as there was a meridian flip involved somewhere.

Thanks very much Bo. Not bad detail with the Canon.

Indeed, Dark Skies rock. Thanks for comments. I had loads of issues doing star registration with this that was caused by using an incorrect Bayer Matrix in PI. Been a while since I have done any DSLR processing.
Just had to look up what Grouse meant in Urban dictionary. I reckon you must be the only person I see using this but apparently its common usage in Melbourne? Thanks!

Personally I would go for a bit more saturation but as I'm inclined to overdo the saturation on my own images take that with a grain of salt or two.
Thanks. I just took a quick look at the saturation after reading your nice comments but going to leave as is I think.
I hope you don't mind, but I reprocessed your image for you, a few glare filters added by my amazing phone app, and a slight increase in saturation and a teensy crop to highlight the main target (that Trifid is never that spectacular anyway)
Hope you like it! And I hope you have a sense of humour
Wow, I could really do with that phone app,
but what I really mean is, WTF? Mods!
but in closing I would have to say it does show great imaginative use of technology in complex image processing
Andy? Is that a SH?t Sandwich?
Now excuse me as my wife has just cut up my food for me and I must go and eat

Wow that looks great, like some images taken with very expensive RC's I've seen over the years, when bright stars are around outside the field...so don't worry there are certainly some good star flare removal techniques that could address the issues presented here

Looks more like the moon is just out of field Also some pretty nasty internal reflections so you may want to address those as well.

Sighs heavily..
Allan, thanks very much for your comments. It's a great scope, just wish it came with clear skies.
