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

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.

About a year ago a German amateur imager contacted me about a faint object lying near Aldebaran.  It was visible (just) in an old image of mine which only had an hour of total exposure time.  Just woke up this morning and wondered if the recent Aldebaran 2-framer with 2-hours of exposure time around Aldebaran itself had anything to show.  And yep – there it is :) :) :)

First clear night in 2 months last night – so I quickly grabbed this 2-framer of Aldebaran with the Sky 90 array.  2-minute subs and 1-hour per frame.

As there has only been one imaging night for the whole of October 2015 I have had to look for other things to get on with.

I took a Sky 90 image of the R Coronae Borealis (RCrB) region in August 2013 and again with the Canon EF 200mm DSLR lens in May 2015.  In August 2013 RCrB was at its minimum around mag 14 or 15, and in May 2015 it was around mag 7 to 8.  I put the two images together in an animation that you can see running here.

Once again, before the Moon came up I went for the V1331 Cygni region with the Sky 90 array, this time using 15-minute subs.  Got a total of 14 x 15-minute subs which were added to the earlier 15 x 10-minute subs, and this was the result :)

Managed to get 50-minutes of imaging done on this region before a blazing Moon came up using the 3 x Sky 90s, so 150-minutes total using 10-minute subs.  Needs a lot more on this region, including I think the frames above and below this one.

Beautiful clear evening last night and I put the Sky 90 array onto the Kemble’s Cascade region.  For around 8 years I have wanted to get a 4-framer of this one but didn’t have the time to allocate to it.  Now with the array I can do it in a single evening :)  So here I present a Kemble’s Cascade 4-frame mosaic taken using the Sky 90 array in just over 3 hours actual imaging time.

This was a test shot having removed camera 2 for re-flattening on the laser pen rig.  Short gap in the clouds gave me half an hour’s imaging time on the M57 region in Lyra.  But only half an hour means a respectable hour and a half with 3 x Sky 90s :)  So the image below is 9 x 10-minute subs taken using the 3 x Sky 90s and 3 x M26C OSC CCDs.  This test shot led me to realise something else.  As I can get a reasonable frame in just 30-minutes, I can put a Sky 90 4-framer together in just over 2-hours.  So a project that would have been a multi-night effort can now be done in a single evening – now can’t wait to get the first Mega-WASP 4-framer :)

I just found a folder full of Carbon stars that I had not loaded up to Flickr or the NFO site.  Liked this one the best, and decided to make it the Image of the Month for September 2015 :)

A beautiful pair of Carbon stars in the constellation Sagitta.

Only 9 x 10-minute subs from the Sky 90s and M26Cs went into this one – but as that is clearly enough – it has got me re-thinking how best to use the Mega-WASP array for my work.
