Description

I am in the middle of doing an image that is close to the zenith... With my SkyshedPod, I cannot image close to the zenith so I had to wait for my subject to re-emerge from the "dead zone". With really nice conditions I did not want to waste, I pointed over here and started blasting away... Not bad for a "filler". Gonna complete this with RGB.

Update: I added the RGB to this and decided to publish it... This is a little difficult because of the brightness of M104. Still not quite happy with the background because I think it is too dark as a result of trying to reduce the brightness in the galaxy.

I think this is not bad considering a 800mm FL and small image scale. Because of this, viewing this image at full resolution is better for the galactic details.

Uploading a cropped version... Can't make up my mind on this one. I like the wide-field but the details of the galaxy cannot be well seen. Hence this cropped verion.

I've learned a whole lot about processing during the last few months. This image always bothered me a little. I believe this is far superior to the previous efforts. I have to resist the urge to go back and re-process every image I've done, lol... Any comment/criticism encouraged!
