So i had wanted to try this for some time but the time has just slipped by. The Sigma Lens at 500mm should have been able to pick out the complete system but the whole setup was not very stable that night and all that was achievable was a 1 min sub frames -- how ever i managed to take 240 of them at ISO 12800 -- maybe a little too high ! So here is the result -- its faint but the level of the dark nebulae is amazing the elephant trunk is visible as shown in the this crop
IT HAD TO BE CLEAR! There needed to enough dark and enough time without work! and there had to be a small moon (although it is at 1st Quarter.) When all of those items come together then its Telescope time !!! If only the bugs knew to remember this fact Image a couple of objects here is the first on this is a 25 min combination of the Lagoon M8. A series of 5 min Subs were used and stacked in Pixinsight etc.
OK so i could not resist this but here is a 1 hour 50 min collection of 5 min sub frames stacked of M33. I also have a 2 hour set of data from the sBIG on the object from the evening before yet to process -- interesting comparison coming up. The image below is from the Sigma 150-600mm lens using the 6D also
