First Astro Photo - M57

Postby Graeme1858 » Tue Jan 08, 2019 9:17 pm

It's been clear all day here then it clouded up when I got home!!! I set up anyway to try the new usb hub. Then it cleared so I aligned the mount and pointed the telescope at M57.

Here's my first proper astro photo:

10 x Lights, 10 sec, iso 1600, (was going to be more but the clouds came back!) 10 x Darks, 10 x Bias, no flats. Stacked in DSS. A quick dabble in Gimp but I don't really know how to process yet!

A challenging object for your first photo! It is a nice sharp photo. A 20 or 30 sec exposure will really make the Ring Nebula light up.
I use an 11" reflector (Celestron CPC 1100) and a 3" refractor, (Sky-Watcher ST80) mounted on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI 120MM, ZWO ASI1600MC and Canon 1300D for imaging.

Cheers for that. It would have been nice to experiment with exposure but the clouds were gathering so I just did 10 seconds. I set it up for 20 exposures but aborted after 12 because of the cloud.

The strong winds that we have been having mean that it can go from clear to cloudy in minutes! It isn't helpful for long observing sessions. :( It is probably best to start with lower exposures. At least you have something to show from the session if you have to stop suddenly. That's the way I do it anyway.

Planetary nebulas are my favourite, but they are not the easiest target. The Ring Nebula is such a great object to observe because the shape seems to be so unlikely.

I hope the skies clear for you soon.

The high air pressure that's been sitting over the country appears to be moving off over the Atlantic. Hopefully that will clear the clouds. I've got seven days left on my Backyard EOS trial licence!
