Images taken with the 10-Megapixel Starlight Xpress M26C one-shot colour CCD and the Sky 90 refractor.

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.

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.
