M33 from New Mexico Skies Reduced ImagePosted By Greg Bradley |
Great shot.
The way to reduce in Photoshop is: Image/image size/click all 3 boxes on the left side if not already clicked, then 800 x 600 is the usual size/enter.
Then save as a jpeg and use the slider to control the file size.
It has to be under 500kb to go on Astromart.

Need Some "Steering"Posted By Greg Bradley |
M42 is difficult in that the bright core will brun out first. It really is a multiple exposure shot.
ISO 1600 is good for a rapid imaging and I know some advocate lower ISOs but not sure about the benefits and this has been the topic of some discussion on various groups. I think tracking weakness will utlimately be the determining factor where maximum ISO gets you "out of jail from tracking errors". Even ISO 3200. 3200 will give you a lovely bright image in 2 minutes that will bring out a lot fo detail but will burn out the core. Tak a series of 10 second exposures for that. Then you need photo shop skills to layer in the shorter exposure to replace the burnt out core.
If that is too much for starters then stick to the ISO800/1600 and 90 seconds. I would think ISO400 would be way too dim.

Nice work.
How did you get the bright star at the righthand side of the nebula under control? It usually blows out as well. Was that also layered in?
