M81 M82 and updated page


Adaptall

Recommended Posts

Hi everybody,

Here is my latest attempt on M81 and M82.

A better quality edition can be found on my newly updated photography homepage:

http://www.avphoto.dk

I've used my Skywatcher 150PDS on an EQ5 GoTo mount together with my canon 6D.

A total of 32 exposures range from 40-80s at ISO 4000-8000.

Photos were stacked in DSS and modified in photoshop. I do not have a field flattener, so the stars in the periphery are not too nice.

Nice pics lots of detail there.

Some reprocessing suggestions:

You can create a set of darks in the fridge. And then restack with dark calibration on in dss to Match noise to temp.

You should look into creating a artificial flat using gaussian blur at 250 then layer and subtract it in PS5.

A star mask can be used to enhance star and galaxy core colour.

Image analyser is a good free way to de noise.

Have fun and don't forget to Google concepts, great tuts on youtube.

Hope suggestions are useful.
