CCD Astrophotography Images

One way of taking a high resolution zoom-in zoom-out of a deep-space image is to take the region concerned at 2 different focal lengths, or to take a single frame and then a mosaic of frames of the region. This image showing the Running Man and the whole of the central part of the Orion nebula uses a combination of both techniques. The Running Man alone is a Hyperstar image taken at 550mm focal length, and the central Orion nebula image is a Sky 90 4-frame mosaic taken at a focal length of 450mm. Enjoy 🙂

I have very deep data of M13 and for the first time today I took a good look at the image to see if I could find “The Propeller”.

And there it was!!

I think somebody up there knew it was my Birthday today and kept a clear pocket of sky over the New Forest Observatory last night when the rest of the UK was under cloud cover.

Here are 9 x 5-minute subs taken on a single Sky 90 with a 1-minute gap between subs.  The asteroid was moving in the constellation Canes Venatici and the bright star in the centre is SAO 63515 for reference.

I have a whole bunch of subs taken on the two 200mm lenses from last night and haven’t even had a chance to look at them yet.  More goodies to come.

I saw on the Sky 6 that there were 3 bright asteroids in Leo, namely 16 Psyche, 29 Amphitrite and 62 Erato.  So when I processed the data this morning and only saw 2 I wondered what was wrong.  Checked on Guide 9 and there was no sign of Erato in the FOV, so the Sky 6 got it wrong for me.  Thanks a lot.

Found I had this one on the hard drive while processing last night’s Procyon data.

This is the bright star just above Procyon – Gomeisa.

15 subs of 15-minutes taken with the Sky 90 array and M26C OSC CCDs.

No Moon and some clear sky between 8:15 p.m. and 10:00 p.m.

Set up the 2 x 200mm lenses on the Procyon region for the first of 2 frames containing Procyon and Gomeisa.  Got the Procyon frame and cropped it down to fit with some earlier Procyon data taken with the Sky 90.  Here is the Registar bolt-together of the 2 datasets.

11 x 9-minute subs with the 200mm lenses and M26C cameras from last night.

Around 3-hours of 10-minutes subs from the Sky 90 and M25C from earlier.

And here’s what can be done with my data when Noel Carboni (Florida, U.S.A.) gets his hands on it.

Sure hasn’t lost his touch!!

I composited last night’s deeeep M45 data with some older shallower data with good colour and ended up with this result:

Yet another beautiful clear Moonless night last night – and best positioned for some deeeeep imaging was M45, the Pleiades.

Managed to grab 18 x 40-minute (yes that IS 40-minute!!) subs and very quickly processed (leaving in the plane trails) just to see what I caught.

This shows more of the faint stuff in the region than I have managed to grab before with this kit.
