M101... Still experimenting under EXTREME light pollution.

[AlexxxAA]

For the past two months Ive kept experimenting with my equipment to get the best results as possible.

So far, it seems that in order to get long subs, i have to bring down the ISO to 200 or 100 in order to not pick up he skyglow from here in the Los Angeles suburbs.

Here is 14 x 5min, ISO 100, with the Baader Neodymium through the 8" f/4 newt. Guided with the ZS80ED II. Plus 9 darks and 9 (laptop) flats.

This is so far my results that i wanted to share with everyone. Im hoping that in the next days i can add another hour or two of data, and try a different method of flats, and see how much that helps

Thanks to everyone for looking. All comments are welcome. Clear skies

You picked a very faint object to have a bash at!

I hope you don't mind- i ran the PS Filter Gradient XTerminator, duplicated the layer, Gaussian blur the Subtract to remove the heavy gradient. Any better?

Is gradient xterminator a PS plug-in??? I dont recall...

Thanks alot!!!
