IC1831 region in Cassiopeia

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 :)

Rosette final twiddles

Carried out some final (?) processing twiddles on the Rosette composite – think it’s just about there now :)

Rosette composite definitive

Handled the old data slightly differently in this Registar composite reprocess.

Monkey Head nebula composite image Rosette nebula composite image

Registar was used to align old Rosette and Monkey Head nebula data with that taken recently to form a composite image with even more data :)   Here are the results.

NGC752 or Caldwell 28

The 2-billion year old open cluster NGC752 in the constellation Andromeda – together with a whole bunch of faint fuzzies (galaxies) in the background.  North is up in this image.

NGC7380 emission nebula in H-alpha

An H-alpha narrowband image of NGC7380 in Cepheus taken way back on October 11th 2008 – just found unprocessed on the HDD this morning :)

IC1831 region in Cassiopeia

I revisited and reprocessed this data to see if I could find any of the nebulosity reported in the Sky 6.  There is some, but it is pretty faint throughout the region – you can see the very edge of the Heart nebula bottom right, so the faint stuff is almost certainly part of this.  One thing’s for sure – there are a lot of stars!

Galaxy group in Bootes Galaxy group in Bootes in B&W

I have no idea why I took this image of a galaxy group in Bootes on January 29th 2011.  I also have no record of it in the logbook.  I ran an astrometry check on it to find where it was – the bright star near the middle is magnitude 4.80.  Apparently this is 19 sub-exposures at 10-minutes per sub, so for some reason I spent 3 hours of good imaging time on this one – if only I could remember why :)
