But, of course, Fred. <g> It also depends upon your focal length, pixel size, well depth, sky background, filter transmission, and so on... There are so many variables that it often helps to let the m

I use a baby monitor to listen in on the observatory while I'm in the house during an imaging session. My MI-250 mount would interfere with the monitor if it didn't have a choke on it. The choked AP m

Hi Dennis, Long time no hear. It's time to fire up the airplane and take an up high image of the roll-off like the one that you had of the dome. <g> My regards, dan kowall ________

It was a terrible tease to see what the program could do, Ray, and to not be able to take a copy home. <g> I'm a bit of a Luddite when it comes to software, but I can't wait to get a copy for myself.

Hi Rick, I can't answer your PemPro questions, but I have used a similar setup for imaging (except for the field flattener which isn't really needed with the ST10). I do a drift alignment such that I

One caveat to Jeff's advice, Terry: The alkalinity of the bar soap will cause corrosion on many metals. Even though the shafts are stainless steel, most stainless steels contain trace amounts of impur

The greyscale Ha is especially compelling, Brian. Don't be afraid to load up the 1200, it probably didn't even notice the AP130 was riding up there. My regards, dan kowall ______ Brian Coote <dbcoote@
