Thanks for the reminder of my deep space imaging, seems like imaging in Jan and Feb in Brisbane is impossible of recent.
These exposures were from a quarter of a second to one third of a sec as it is so bright so I stacked almost all using Registax only removing the recentered images that showed movement. The detail was shown in the red channel which as usual was quite sharp.
The Mintron (GStar-Ex) is very sensitive and will work at these unusual focal lengths but finding objects at 7 meters FL plus is bloody tricky using star hopping which is a slow process and poor seeing can easily turn stars to blobs, so I had a good night back in 2011.
I never got a look at it through the eyepiece unfortunately.
Regards, John.
