Terrific resolution on the hour glass nebula.
Another stunner.

Thanks very much Greg :-) The trick with the stars is to use narrowband stars (typically H) for the luminance and RGB for the chrominance.

They definitely resolve well though!

Yeah, if you have the money Chroma/Astrodon are definitely the way to go. I've now done an actual comparison with my Astronomik O filter and the Astronomik is much better than the Antlia with regard to halo. Unfortunately the use of an OAG and desire to do LRGB and NB on the same night (automated) mean I can't continue to use the Astronomik, so that's out... I may end up getting an Astrodon 3nm O filter down the line, but I'm very happy with the Antlia S and H.

Thanks Kanga

The scope used was the TS ONTC 8" F4.5 newtonian, with an odd Paracorr that brings it to F5. Camera was an ASI 183mm Pro.

I'd be hard pushed to find a better Narrow Band Lagoon on the web.
Top-shelf stuff.

EXCEPT when they have the exquisite detail and colours of your beautiful rendition Lee! Very nicely done!

haha, thanks Marcus

That's the sad thing about "common" subjects, you can do a great job but most of the time nobody cares because it's just
another image of that same old target. Glad you like this one though :-)

Framed this way it's like being at Sydney Aquarium, looking into one of the giant fish tanks as the diaphinous jellyfish like core of the Lagoon swims gracefully by. 
Will be interesting to see how the new filters perform on dimmer objects.

Thanks Andy! My wife also thought it looked like an aquarium. I'm sold on the Antlia S and H, I expect they'll work fine on targets dim or bright, but the O halos will be annoying.

Thanks Mike!

Yeah, I don't get the fascination with long focal length scopes. It's all about sampling... 0.5"/px is 0.5"/px, doesn't matter if you're 3m or 1m. Of course you need at least a little bit of aperture to go with it, but other than that...
I had been planning on building a bigger (12" or so) newt to put on the Mesu, but I'm just gonna keep the 8" newt... when you do the math, it's actually pretty hard to beat. I could go a bit longer focal length and move to F4, but I honestly have more than enough difficulty with the F5, I do
not want to get a faster scope that requires so much fiddling to get good stars.
Maybe one day as a retirement present I'lll get myself a CDK or something (mostly because I really hate fiddling with newts) but until then...
