Star photography...
 

Hello,
Having recently upgraded to a 6D mk2 which I ordered with a 24-70 f4L lens, I thought I'd try again at shooting the stars. (Before I decide if it's really worth the extra expense of upgrading to a faster lens.....)

I took this tonight, I like it, but it is a bit of a rough photo.

Is there anything more that could be done during processing to get rid of the noise without compromising sharpness?

Have you considered video frame stacking? It's the default method to raise signal to noise ratio. The standard technique for astrophotography.

Being honest, I've never even heard of it!
I'm considering doing a milky way photography workshop which is run sporadically near me.

Dabbled a bit taking some pics thru my scope... The three better pics of Jupiter were imaged using Registax. Stacking programmes are generally used for cleaning up pics of galaxies, nebulas and planetry objects mostly due to them needing multiple points of reference to align multiple images and then take out the differences between them. The more frames you get the better the result. If you could get enough bright stars to align by then you should see some results. the Jupiter pics were resolved using 700-1000 frames from video footage.

Wow, they are awesome photographs! You mentioned at the bottom that you used your phone!?

Thanks :)

Yes but don't forget that the optics that matter are in the eyepieces used rather than the camera. If you look at some of the earlier pics of the moon you can see the limits of the 1 1/4" eyepieces i was using before i got some decent 2" optics giving a much wider field of view. It also helps that i have retrofitted my mount with full guidance motors and goto electronics.
