CCD Astrophotography Images

Beautiful clear Moonless night last night but we only get astronomical darkness starting around 11 p.m. so it’s a late start at this time of the year (and darkness ends around 3 p.m. so you don’t get many hours of darkness either).  I saw some nice contrasting red and blue stars in Draco using a planetarium program, and as a bonus I could also get NGC 4236 (Caldwell 3) in the frame as well – a barred spiral galaxy.  This image is 30 x 10-minute subs taken with the Sky 90 array on the mini-WASP.  When I packed up for the evening there was Saturn near Antares in the south, and quite high up in the sky there was Lyra and Cygnus, so summer is clearly not far away 🙂  All in all a superb night’s imaging.

12 frames using the Hyperstar III and M25C camera with 2-hours of 10-minute subs per frame.  Also a 200mm lens with M26C camera 2-framer using 15-minute subs and 5 hours per frame.  So total integration time is 34 hours 🙂

Turned out rather noisy for 30 x 1,000 second subs with the Sky 90 array.  Not sure why as there was no Moon about.  Maybe I forget to turn the Peltiers on??  Need to redo this one with the Hyperstar III.

4 hours of 10-minute subs from last year with the Sky 90 array.  Akira Fujii effect.

The Sky 90 array was set on this object to see if I could pick up the 3 quasars near this galaxy.  No sign!! A day later I put the Hyperstar III on the same region but only got 4 x 10-minute subs 🙁  Possible sign of one of the quasars, but no sign of the other two – not a fair test however.  Below is the Noel Carboni process of the Sky 90 data.

A Sky90 image of the Rho Leonis region.  Rho Leonis is a very blue star.

Here is a Sky 90 4-framer of the Merak region in Ursa Major.  You can see the “broken engagement ring” the Owl nebula (M97) and M108 in this image.

Taken last night – 18 x 10-minute subs with the 3 x Sky 90s and 3 x M26C OSC CCDs.

Carbon star T Cancri.

Noel Carboni put together a bunch of Polaris subs we had and I overdid the curves to pull out the very faint Integrated Flux Nebula (Galactic Cirrus) lurking in the background.

Very surprised at the amount of Cirrus that came out of hiding.  Helped by data from clear Moonless nights 🙂

Due to a series of mishaps I only managed to get 15 x 20-minute subs on this one last night using the Sky 90s (should  have got 27 x 20-mins).  This is the IC2087 region in Taurus – and is the biggest region of dark nebulosity I have ever imaged.  Hopefully I can get some more data on this region shortly.
