ASTRO: M33 LRGB
This is a combination of some RGB data taken using the PL39000C on the
AP155EDF f/7 along with unfiltered luminance from the ML8300 used on the same telescope, but with no filter I had some superb seeing on the last night of luminance collection using the ML8300 and AP155EDF: I was measuring 1.3" stars unfortunately not all of the data was of such high quality :-( this may be a bit excessive: I have 90 x 5 minutes of unfiltered luminance (7.5 hours) along with 3.25 hours of RGB (11x15minutes) for a total of 10 hours 15 minutes I've been doing tricolor emission line for so long that I have pretty much had to go up a steep learning curve to do an LRGB. http://www.narrowbandimaging.com/m33...9000C_page.htm I have some Red and Green data taken using only the ML8300 but haven't got enough Blue to substitute it just yet so my color isn't quite as saturated as I know it can be to make the image a bit more vivid Initially I thought it had insufficient data in the luminance (looked grainy) but then I realized I am actually seeing a very high density of stars through nice optics with a fine image scale!

Richard,
maybe a bit on the blue side, but otherwise an excellent image. Stefan "Richard Crisp" schrieb im Newsbeitrag ...
