NGC 6744 Pavo Galaxy from South Coast

[Startrek]

Currently imaging NGC 300 which is my last galaxy for a while as heading back to light polluted Sydney tomorrow. On Tuesday night captured NGC 6744 a large face on spiral galaxy located in the constellation of Pavo with a brightness of magnitude 9.14. It was discovered in 1826 by James Dunlop a Scottish astronomer at his small observatory at Parramatta Sydney
Conditions for imaging were excellent ( no wind, no moon, no dew, low Jetstream, good seeing )

Thanks for looking, comments always welcome

Nice one Martin. I always enjoy seeing Galaxies with a bit more focal length than I use.

Another great one, Martin. You have set a lot of benchmarks for us people with modest equipment.

Very nice Martin.

Thanks Tony , Alex, Kevin and Paul
The stars are a bit bloated due stretching a little more to expose more detail in the arms ( you rob Peter to pay Paul )plus this object was descending from 50 degrees when I started imaging down to 27 degrees when I took my last sub , so not ideal location having to push the optics through all that atmosphere
Any a pleasing result all the same

On another note , as mentioned I was imaging NGC 300 last night , everything was going well with 5 minute subs , DSLR was running at 25 degrees , great guiding , good focus and framing spot on. Got to frame 27 until I hit the meridian, EQMOD put my scope back into park position, then I slewed up to NGC 300 again on the west side , once again good guiding , good focus and framed up well. Then I experienced something I’ve never seen before , my first 5 minute sub was smeared with red pixels across at least 75% of the frame , histogram showed green and blue ok tall and thin together but red was low and fat to one side
So tried another 5 minute sub , same thing , tried a 4 minute and 3 minute sub , same issue again but not as severe
DSLR sensor temperature was exactly the same as on the previous 27 x 5 minute subs on the east side
At first I thought it’s smoke haze but causing the red to blow out but it can’t be as the first 27 subs were fine
Camera appeared to be operating ok , no warnings or codes
It was 1.00am and fighting to keep alert so I shut down and went to bed.
This morning I switched on the camera and it came on ok , took a few random shots without the lens , they were bleached out of course. Had to pack up and leave for Sydney
Any ideas what may have caused the red pixels smear ???
I won’t be using my scope and test my camera again until next week now.
Appreciate any advice
