First light TEC180mm Fluorite 15:20 hours
This is first light for this magnificent telescope.
I thought I would do a classic - The Horsehead Nebula.
Longest exposure time ever for me. A total of 15 hours and 20 minutes.
TEC180mm fluorite triplet with TEC field flattener at F7, FLI Microline 8300, Astronomik RGB filters, Baader clear filter (no UV or IR coating for maximum transmission), Astrodon 5nm Ha filter.
Tak NJP mount, taken at my dark site over 2 trips.
HaLLRGB 450 120 120 120 110 120 for a total of 15 hours and 20 minutes (same luminance used twice in the image).
The Ha on this object is very dim but the clear filter really worked well so a 10 minute subexposure was quite bright and detailed.
NJP mount handles this scope (probably only just) which weighs about the same as my AP140 (16.5kgs).
My favorite is the crop:

I am stoked with the performance of this scope. 
Here is a link to a photo of the setup:

That is a seriously excellent image .
Great image to open the account - perhaps one of the best shots I've see.

WOW, The detail is magnificent. What a grasp on light. I can't wait to see something quite delicate like Crab Neb.
Lovely detailed image.

Yep, great first light Greg
Although it is a good image, with so much data it looks like you have rushed the processing just a tad (nothing a repro wont fix ) but never the less....you have a great scope there I can see and as I predicted already, I recon you will do lots with this scope and the big 16803 chip now  .
By the way what was the effect of bright Alnitak? Did it cause rays in the image that you had to work on?
Aaaaaand how do get to do sooooooooooooooooooooo much imaging mate?? Sheesh

Good on ya.

Greg.... Daaaaaaaaammmmmnnn!! The detail is immense.. I love the faint detail in and around the horsehead.. little tendrils of dust and cloud...
That scope is a MONSTER!!! The pics of it that you showed earlier on the floor, and in its case just did not do it justice... Up on that NJP its just MASSIVE! I love it!
Ps - Faaantastic first light mate... Absolutely stunning in every respect.. As Doug said, I cant wait to see something very delicate from this scope...
Despite saying so much in this post.. im rather speechless !

Thanks Mike. Not rushed, I did 12 versions and from the ground up twice.
You can always change something around. I sat on it for a while until it wasn't improving so I am happy with the processing at this point.
My dark site has reverted back to its former weather patterns which is clear skies all night 8 out of 10 nights. Last year it went through a wet and cloudy period where it was cloudy in the no moon week 8 out of 10 times.
So for example last weekend I had 3 and half clear nights where Sydney probably was cloudy all night.
Greg.

You didn't say how Alnitak behaved in your image..?
