ASTRO: 8 hours of Sulfur/Hydrogen and Oxygen in IC1396
Finally this is starting to take shape
It is at about 8 hours of exposure I am finding a number of issues that need to be investigated. Mostly it seems that there's some mechnical play inside my lens that is causing it to wobble a bit when it is straight the stars are good edge to edge but when it wobbles some of them get distorted. probably a screw worked loose and it may be very hard to get to... Still no flats or darks yet.... I've tried posting this at higher rez twice today but it doesn't seem to be going through. apologies if they all end up going through and we have three or four such postings :-)

Richard,
as usual your images get better and better with more frames added... Stefan "Richard Crisp" schrieb im Newsbeitrag ...
