Re: update

Just wanted to file an update- I am back to using 10 sec exposures at 14mm, the colors at 10 sec seem to be much better than the ones at 13 sec, I'm not sure why.  I recently did a test of exposures between 6 sec and 13 sec and 10 sec came in first, followed by 8 sec and then 13 sec, 6 sec came in last.  Also since I am stacking, 10 sec exposures much easier to determine total exposure for than 13 sec exposures are

As an aside, what is the degree separation between Bellatrix (in Orion) and Sirius? I want to find the right focal length that gives me the tightest view of this area.
