CCD Astrophotography Images

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.

Hind’s Variable nebula, Struve’s Lost nebula, Burnham’s nebula, NGC1555 – they’re all the same thing and it is the orange thing in the centre of this image.

A beautiful clear night last night allowed me to grab 41 x 20-minutes to go with the 24 x 20-minute subs taken in 2014.

Got 6 x 20-minute subs with the Canon 200mm lens which I added to some earlier Sky 90 data.

I managed to get a further 10 hours to add to the initial 7 hours taken using the Sky 90/M26C array – 20-minute sub-exposures.

I don’t think that the additional 10-hours added much in the way of depth to this image, but it did mean that I didn’t need to use any noise reduction like I had to with the 7-hour image.  This is worth remembering for future “marathon” imaging sessions.  Probably not worth going beyond the “magic” 8-hours per frame.

Last night I got 7 hours of 20-minute subs on the NGC6914 region using the Sky 90 array.  The result is shown here.  As it is clear (and now Moonless) I am going for a bunch more 20-minute subs tonight to see if I can improve the image at all.  The first bit of real experimental imaging work I have carried out on the Sky 90 array since putting it all together.

I have a feeling I know what next month’s Image of the Month might turn out to be.

Here is the New Forest Observatory Image of the Month – last bit of data acquired only last night.

This is a 2-framer of the Heart nebula region taken using the Sky 90 array and the M26C OSC CCDs.  The lower frame (captured last night) is 8-hours worth of 20-minute subs and the upper frame is 5-hours worth of 20-minute subs.  The frames were assembled in Registar and processing was carried out in Photoshop CS3 using Noel Carboni’s Photoshop Actions for Astronomy.

Although this could do with still more data I need to move onto something new for my next target.

Last night I managed to get 10 x 10-minute subs using the Sky 90 array on the Cygni 32 region.  Pretty amazed that I could see some nebulosity with so few (shallow) subs.  Anyway – main point of the exercise was to get the two Carbon stars just above Cygni 32 and about equidistant apart from it.  These are U Cygni (on the left) and SV Cygni (on the right).  I combined some earlier HSIII data on just U Cygni with the Sky 90 data for this result.

A while back I asked for submissions to run a deep-sky image of the week from this site. The response was not good. In which case I will post up a deep-sky image of the week from my own collection. I’ll kick off with this recent very wide field of the Cocoon region taken with the 2 x Canon 200mm lenses and the Trius M26C OSC CCDs.
