All the adjectives I could think of seemed trite. Beautiful work.

A shot with the K-5 IIs and 16mm f/2 Samy @ f/3.2 and 92 seconds at ISO 3200. A bit over-processed, but I was pulling out some decent details from the raw file.

Beautiful.

92 seconds? You used the astrotracer then?

Comet C/2013 V5 (Oukaimeden) has been scooting past the Rosette nebula over the last couple of days. This is from last night with the ED100 at F7.2 and Pentax K-5. Didn't get as much time on it as I would have liked due to cloud and me screwing things up. It's only 7 minutes. My special interest in astronomy is comets, or at least photographing them.

The Sigma 18-35mm f/1.8 is a excellent lens for wide field astrophotography with the O-GPS1


Pentax K5IIs - Sigma 18-35mm f/1.8 @ f/1.8 ISO 800 30" astrotrace.

I used my equatorial mount. I am going to try the Astrotracer at some point, but an equatorial mount guarantees perfect tracking every time without calibration issues that I often hear about. When I shoot a frame I don't want it to be an experiment.

Ah, even better, yes. I'm thinking of getting a motor drive for my telescope's mount (then I'd just have to learn to polar-align it).

Kevin that's awesome! Didn't know that the comet was so close. I'll have to give it a shot tomorrow night now that Rosette has set. I had a blast tonight - Here is M27 the Dumbell Nebula with the ED100, F7.65 with the flattener on... pretty happy with this one!

Nice images Mike. You gotta be happy with those. I can't quite get an angle on M31 from my setup point. It's directly behind a street light.

The comet has now moved away from the Rosette nebula as it heads towards perihelion.

Thanks Kevin! I'm doing the Helix nebula tonight - here's the rig in action (K3 on scope, pic taken with K5. 6 seconds, ISO6400, F3.5x10 frames stacked in PS to reduce noise). I'm making the most out of these unusually clear, calm and crisp nights! Barely a flicker from the stars tonight even though the jetstream is 46m/s. Good seeing conditions though (3)

Jeez that's a nice helix. I had a go at it a few weeks ago and it was pretty rotten.

Thanks mate! Am tempted to do some shots tonight but not sure if I can be bothered dealing with 90% humidity with the hair drier every 10 minutes lol. Tomorrow night we're forecast for 40-50% humidity so much better conditions
