M33 with an Asteroid in the subs

[PaulR1]

Here is my M33 , Triangulum Galaxy , from 71 x 5 min subs over 2 nights

Was fun to process as two of us also found an asteroid lurking in the subs which can be seen in the processing video near the end

Thanks Paul, 🙂 Very impressive result and useful to compare results between a OSC and my LRGB one I posted yesterday. I'm told my background is too dark. 😀 The Ha regions show up very similar between the two. I binned mine early on in processing, primarily to speed up processing as Startools was a bit slow with a 62 mega pixel camera. 😄

Also, like the bonus video end. 😀

Lovely image, well done.

It is a great image of M33, perhaps my favorite galaxy. I really enjoyed the video too. The asteroid track is the icing on the cake!

Great image and the video was an added bonus, thanks for posting that too.  Really enjoyed the asteroid piece at the end.

Very nice image!

Wish I had that much Ha in my M33 image!!

Lovely image & thanks for the video, it was very interesting.
Out of curiosity, couldn’t you have used the starless image that starnet created as a galaxy mask, perhaps after extracting the luminance?

Thats not a bad idea actually , I might wind back in the project processing and have a look at that and also for future projects.

One thing I tried for the first time recently with a widefield image of M33 I took with my dslr,  is to actually use the starless image itself. I was able to work on the Galaxy and background easily without the stars getting in the way. I also stretched the stars separately in another image before adding them back into the starless image with pixelmath after first applying the star mask. As I only had 8 images to stack I think this helped me to get a better image than otherwise. 
If you’re interested the image is near the bottom of page 33 of this thread.
