I am an astrophotographer I mostly use my higher end scopes and mono cam imageing the cosmos in narrow band (H Alpha), composites of still frames of very long exposure times of fifteen min or oore-- this was the result of a test using time lapse technology--
Image renedered form my timeplapse capture using pro gear,
I mostly use my 70mm Triople refractor or my 8 inch scope and my 2k ZWO mono camera to mage the cosmos but this is rendered from a time lapse capture using a 14mm lens and my Nikon D 810 dslr-- just unbelieveable
The sequnce is 3 sec per frame 60 fps 5 sec apart interval is 0.1.25
