With Christmas rapidly approaching, and the International Year of Astronomy rapidly drawing to an end, I thought it appropriate to post a Festive deep-sky image. This is the Christmas Tree cluster (NGC 2264, 2,500 light years away in the constellation … Continue reading
Unbelievably I managed to get some imaging done on the night of Thursday December 10th 2009 – the last image I took was on October 25th 2009! Got 4-hours worth of 4-minute subs on the nice little open cluster in … Continue reading
Noel has been really busy recently with a number of projects and the NFO data backlog has been steadily growing. As we have had the most atrocious weather all weekend I decided to have a go at image processing some … Continue reading
I just processed this image taken back on 18th April 2009. The galaxy in the centre of the field of view is NGC 4008 in Ursa Major and what appears to be a bright nucleus is in fact the supernova … Continue reading
Noel has just reprocessed an earlier image of Gamma Cassiopeia with the nebulae IC59 & IC63 lying close by – with the addition of some star spikes.
The third clear Moonless evening in a row had me out to capture this beautiful little open cluster in Cassiopeia called the Owl or ET cluster – NGC457. As I mentioned before, Noel’s real speciality is stars – which you … Continue reading
We’re on a roll 🙂 The weather has not only been unusually good these last few nights, but they have been Moonless nights too! Excellent!!! Managed to capture the Double Cluster a couple of nights ago and Noel worked his … Continue reading
Noel recently processed an image taken just a few days ago. This one is NGC281 also known as the Pacman nebula in Cassiopeia. Twelve subs at 15-minutes per sub gave this result, and 15-minutes at f#2 is equivalent to an … Continue reading
Noel has just processed the H-alpha data from Thursday 10th September 2009. This was the first target using the new 45nm bandwidth H-alpha filter (Baader) I purchased from Ian King Imaging Ltd. This is 10 subs at 10-minutes per sub, … Continue reading
Conventional narrowband filters (12nm or smaller bandwidth) do not work with the Hyperstar III system due to its very low f#. The cone angle of the rays passing through the filter are so far from normal incidence that the actual … Continue reading
