This is a Celestron RASA image (f2.22) using a Nikon D800 imaging dslr camera using my past mount of a ioptron cem60, of the Western Veil Nebula. And
I have a question about why is that yellow star's spikes shaped that way....sorta
flattened on opposite sides and then spikey on the opposite corner (90 deg) sides?
Is it my collimation? Wouldn't think so, since the Celestron RASA was factory new.
Was it the weight on the corrector plate? Making those disturbances? Too much weight? Or was it temperature? Of out of focus?
someone please send me email at:
davewilliamstar@live.com about this?
Thanks!
