Some more old data off the hard drive – this time from 3rd March 2011 – 47 sub-exposures at 5-minutes per sub using the Sky90 and M25C combo. NGC7788 and NGC7790 a pair of open clusters in Cassiopeia – North is to the right in this image. You can also see a small region of emission nebulosity which I can’t find on The Sky 6. Anybody know what it is?
You will see in the comments below that Tom How identified it correctly as SH2-168. The reference to CTB1 is an “in joke” 🙂
Sharpless 168 I think. Lots of sharpless objects around there. Suggest you download some extra catalogues for TheSky – I can’t work without the sharpless catalogue installed in Skymap.
Yep it is SH2-168 you can show me how to download extra catalogues for The Sky 6 – I have absolutely no idea how to 🙂
oh, I’ve twigged it now. CTB1 🙂
No – it’s not my Nemesis 🙂
No no – not a joke. You can just see CTB1 in the upper right of your image. Either that or my navigation is miles out.
Of course you are right!! I took this one on 3rd March 2011 and I’d completely forgotten why I’d taken it. This is the starfield background for CTB1 in case I ever get a decent image of the supernova remnant. Only a few months and I’d forgotten all about it – this is what retirement does for you 🙂
Perhaps a nice new observing log book to complement the new observatory.
I hate to say – I do have one – and this is all written down in there – but I didn’t look it up when I did the processing 🙁
oh dear, i fear you are beyond aid!
