I Haven’t posted any images recently even though there have been a couple of nice ones (due to laziness), but this one prompted me to get writing.

It’s that time of the year again when Orion is up there waiting to be imaged.  This represents over 10 hours of RGB (no H-alpha yet for those in the know), and probably about the same amount of image processing time from my collaborator Noel. Read the rest of this entry »

We have three images in the 2007 yearbook 🙂 :

Page 38 is the 4 frame Hyperstar image of M31 as one of the top 10 images of 2006

Page 72 is a Hyperstar image of M13 as a summer object

Page 97 has the Virgo Cluster as “deep sky delights”

I’m thinking ahead about the deep-sky object that I will concentrate on for the short summer nights.  I am really impressed with the image of the Veil nebula on Davide de Martin’s Skyfactory site where he has processed this superb image using Palomar POSS II data.

I think I’d really like to give this one a good try, however that field of view (FOV) of 4.2 x 4.4 degrees would mean a 2-frame mosaic with the Sky 90/M25C combination, and I’m not too happy about spending that much time on just one object, especially with short evenings.

However, Steve Cannistra has also imaged the Veil region with a set up that has a very similar field of view to mine and although it doesn’t get the whole of the region in the frame, it still makes a very impressive image.

Taking all things into account, I will try to get a very deep single-frame image of the veil region using the one-shot camera and the usual Hutech IDAS light pollution filter. 

I know from the previous work I carried out on the Witch’s Broom region of the veil with the Sky 90/SXV-H9C combination that the one-shot is fine for this purpose. 

The only thing that I don’t know is how good (or not) the one-shot will be at picking up the faint stuff between the Eastern and Western veil regions.  I guess the only way to find out will be to image the thing this summer 🙂

I’m going to be posting more about the Veil Nebula project and you can follow my progress in the Veil Nebula Category or by clicking on the links below [which also happen to be from the Veil Nebula category]:

The diagram from Cartes du Ciel will give you an indication of where the Veil Nebula is in the night sky:

It took over a year of posting images before it finally happened!  Astronomy Picture Of the Day (APOD) have chosen our picture of the nebulosity around the supergiant star Gamma Cygni as picture of the day – today! Read the rest of this entry »
