Hyperstar III data taken on 30th May 2012 – 20 subs at 5-minutes per sub, f#2, 11″ SCT.

The version below – but a little brighter

Looking at this image with fresh eyes this morning rather than towards midnight last night – it looked to dark overall, so brightened it up a bit.

This is a composite image showing the Leo Trio region.  Hyperstar III data taken on 21st March 2010 has been combined with older Hyperstar 1/H9C (2-frames) data from much earlier.  The composite was created using the powerful registering program Registar.

North is to the right in this Sky 90/M25C image comprising 33-subs at 590 seconds per sub.  I went very deep with the Sky 90 for this one under almost perfect sky conditions.  To the left of the image the red nebulosity is the top of the Heart nebula, IC1831 is the central region of the image.  As you can see there are plenty of stars as we are in the Milky Way here

Although this image probably only looks a little brighter – it also uses the proper (dual) dataset as well, so there’s a couple more hour’s worth of RGB data from the Hyperstar III in this one.

I actually spent a little while looking at the “Help” instructions that came with Registar in an attempt to see what it does and to hopefully apply it properly to mosaics.  Why has it taken me so long to look at the “Manual”?  Because I had to download some file or other from Microsoft to allow me to see a “Help” file with this Windows 7 64-bit system.  Now why this can’t be done automatically I don’t know – but eventually I read the file.  So here is the recent Monkey Head nebula data properly registered with old Hyperstar I data and cropped down to almost the old Hyperstar I/H9C field.

Managed to get 2 hours of 10-minute subs using the Hyperstar III on 26/01/2012.  In fact I got 4 hours worth of subs but didn’t realise the bottom of the image was being clipped by the trees over the back, so now I know how far south I can image, and it isn’t much below the bottom of M42 itself   So things like the Sombrero and NGC2170 are out of the question which is a shame.  Back to NGC1999.  Obviously this object needs a LOT more data, and the usual 8 hours total exposure time would seem to be about right.  Not sure if I will go back to this one to get more data or not.  In the much larger uncropped image there are also a pile of geostationary satellites, as much as a problem as the satellites that sit in the middle of the Witch Head nebula.  I can always image something else later in the evening of it remains clear I suppose but getting 8 hours of data in 2 hour chunks is a bit wearisome.  Might just move onto something higher up where I can get 4 to 6 hours in one go - we’ll see.

The same final process twiddles carried out on the Registar composite image of the Monkey Head nebula
