M81

[Slawomir]

Due to the lack of clears skies, I dug out some old data collected a while ago through iTelescope.Net - Telescope 18.

Lum: 7 x 300 s (bin1)
RGB: 4 x 240 s (bin2) per channel

Looking good Slawomir. The pink HII regions are starting to show. This is not an easy galaxy to process. You've done very well given the small data set.

A tidy image, Slawomir.

Thank you Jason and Rick.

Hi, Slawomir,

The blue stars/clusters in the spiral arms are razor sharp and extremely detailed. If I stretch your image a tad, I can also make out the dwarf companion galaxy at about 5 o'clock from the main one. Well done.

I wonder if the core is a little burned out toward blue-white, so you're losing some of the yellow-orange colour, and also losing contrast in the dust lanes close to the central bulge. It's a valid interpretation exactly as it is, of course.

A fine image.

Thank you Mike nad Trish,

I also got a feeling the image is generally a bit blue-shifted. I am a narrowband guy and RGB is uncharted territory to me. I was also hoping to get more Luminance data but weather was not cooperative at the time.

Honestly, it is a relatively unexciting image of M81 but I had fun putting it together, instead of watching intelligence-dulling TV.

Looks a little too blue Slawomir and a bit burned out in the centre. The shadows/highlights tool will fix that nicely. Overall a pretty good image.

Cheers

Thank you Steve.

Tweaked colours a bit for a "stronger impact" ;)

In the right direction Slawomir. Generally just lacking exposure length and its hard to get it right with a lack of signal.

Greg.

Thank you Greg. I agree, it needs at least 3x the amount of data, preferably 5x or more. One day, maybe...
