M33 - Second Attempt

[gnomus]

This is my second try at M33 - this time with an ED80 (instead of my C8 Edge).  (My first attempt is here - http://stargazerslounge.com/topic/229639-stacking-images-from-a-nikon-d800/page-2  

This was from my first night out with the ED80 and Canon 600D combo.  Using a ZWO 120 attached to the stock ED80 finderscope to guide.  This is a little over 20 x 5 minute exposures.  Bias and Flat frames.  No darks - I used APT/PHD to dither.

That's really impressive, nice one!

You recommend using dithering then?

I'm a beginner.  I used dithering because that's what others here recommended I do.  

As I understand it, because the camera is moved a few pixels between each shot, different information falls on these pixels for each shot.  That helps with noise and hotspots.

That does look great.

If I can get close to that someday I'll be well pleased!

A very good attempt with a Dslr . M33 is a tricky target and one ive still not come close to mastering.

Dithering with a dslr really does help alot with the final stacked image .

I agree with others that this is a very good capture.  As ever, more data would make it even better, but it's a tough one as the edges of the galaxy are not well defined and the whole thing looks a lot 'looser' than most spirals.

Congrats!

[gnomus]

Thanks for the kind words.  The camera is modded.
