Managed to process the full width of this image which I didn’t think I’d manage to do when I started on this one earlier today.

Managed to squeeze out a bigger crop which brought in the top of M42 at the bottom of the image.

I used Registar to add together all the data I had on the Running Man nebula in Orion.  This amounted to well over 80 hours of total exposure time including some recent 5 x 1,000 second subs from the Hyperstar III.  The reason for the 8-spiked stars is that the spikes were orientated differently in different datasets (I’ve no idea why).

I used Registar to create this composite of Hyperstar I and Hyperstar III data taken of the Whirlpool galaxy, M51.  Around 3 and a half hours of f#2 data taken with an 11″ SCT.  Clearly worth getting even more data in this region.

Hyperstar III data taken on 30th May 2009 – 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.

Taken last night (2nd Feb 2012) in -3C temperatures with a blazing Moon overhead.  Camera 1 on the mini-WASP, Dubhe, one of the two “pointer stars” in Ursa Major.  A nice orange coloured star and another one for the “single star image” portfolio.

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

I have gone for one of my “single bright star” images for this Month’s “Image of the Month”.  This Month’s object is the star Procyon or 10-Alpha Canis Minoris in the constellation Canis Minor.  Procyon shines brightly in this region of sky at magnitude 0.40 and part of the reason it is so bright is that it is very close to us at just 11.41 light years.  With an F5IV-V spectrum, Procyon appears bright white in the sky, and also in this image.  You don’t need very long subs when imaging bright stars, but if you want to capture a decent number of background stars you need to use subs from 3-5 minutes long.  In order to reduce the noise it is a good idea to get at least a couple of hours of total exposure time, though if conditions are favourable you will get a good result with just an hour or so.  As this image was taken with the Sky 90 refractor it is clear that the spikes are “software spikes”.  When a single star is the subject of the image I prefer to see some spikes rather than a bright ball of light with an extended fuzzy outline – but that is just personal preference.  There are some cases (M44 immediately comes to mind) when I prefer no spikes at all, it depends a great deal on the subject and its setting.

There isn’t much apart from Procyon in this region so this one is a case of all or nothing, only really worth taking if you are building up a portfolio of  the brightest stars in the sky.

Until next month – good imaging
