Great work, Allan! Nicely understated colour and good detail. I guess being able to grab data even with our unpredictable weather is the big advantage of that obsy of yours.
Cheers,
Rick.

Thanks for the nice comments Rick and Dennis.
It's great being able to leave everything set up in the observatory waiting for a break in the weather and then walking in and knowing that you can just start off exactly where you left off in a few minutes. It took a bit longer last night as I changed my guiding setup to the WSG part of the QSI camera with the 10" GSO RC as I wanted to see how well it would guide. stars were a little elongated at that focal length but the stars were pinpoints on downloading, so I was happy that I had an alternative to my usual guide scope setup.
Any way glad you liked the final product.
Allan
Both very nice images Allan, the colour version really pops
Did you process with Pixinsight or Photoshop?
Sad to say that I used photoshop for the whole exercise. I must use PI at some stage but it's now mainly levels and curves with some faint sharpening routines.

SGP really came to the fore last night as I just used an image from the last session which had been plate solved to setup the imaging session. I slewed to the object using my planetarium program, did a blind plate solve to see where I actually was, told the scope to go to the centre of my reference frame from the last session. Then did a confirmation plate solve to make sure it was within a few pixels of the last session and just continued on with my imaging session getting the subs that were not captured in the last session.
Worth the money in my opinion.

Looking very nice in colour.
I would like to see a much larger version.
I was not happy with the lack of star colours nor that of the galaxy and thought that the latter was a bit full on and so I decided to do a Sidonio and reprocess the image to make it softer or less vibrant.

Hope you like this version Ray.
I actually like the second one the most, the third has a cast across the whole image. I like the core of the third image but the colour from the second

Interesting that you say that because of all the galaxies the one that I think should be blue is this one. The classic hubble image of this is blue with the HA regions standing out like traffic lights!

Nah nah Lewis
Looking good Allan, all the colour palettes are ok comes down to personal preference probably (blue is good )

Hi Allan,
I like the colours in the first colour version because you can
see the red nebula areas better.
Also there is more detail around the core in the mono version
than is appearing in either of the colour versions.
I would like to see a little more colour in the stars.
Your data is so good that I reckon - wait about a week
& have another go at processing - it will be worth it
just to extract that last 10% more out of your image.

At first I was unsure with sgp, it didn't have planetarium software and moveing in and out everynight I would have no pointing model. I wrote the maker and he asked me why I wanted a pointing model at all? And told me to try without. Since then I have seen the power of it in action. No model not pointed anywhere near the target it will blind solve where it is and still get the scope in the correct spot! Amazing.
Obviously Im going to have to take a step back and try and blend a few of these images together. When I concentrated on the galaxy, the stars suffered. And when I concentrated on the stars the galaxy suffered. So I guess the best option lies somewhere in between which I can see is the case after having left this for a while.
I get so tied up looking at doing one thing and really loose sight of the overall perspective or at least I sometimes do.
The other thing I feel is that I need to get far more colour data as this is where things come apart, but of course the moon is up and a cyclone is hitting up north bringing clouds and rain etc. Ho Hum!
Anyway I guess there is no correct way but glad you liked it.
A final Sidonio will be done and thats it.

Glad you like SGP as I keep finding little things hidden away in the program that really help me do what I want to do.
Just a complete program that is brilliantly supported by the authors.
