Anyone know what this is?

[Spitfire]

Discovered this object whilst testing out my "new" Eagle3s It looks like a Super Nova Remnant.

It's in Cassiopeia at approx. RA: 0h,0m,20s  DEC:62d,29m,38s. It is faint, thin and about 1 degree in diameter. My PHD guiding didn't work so this is

47 x 2 minutes unguided in Ha. It is not a Sharpless object and I cannot see it in any Super Nova list that I have seen. Any ideas?

Tech Details:

Scope: Takahashi Epsilon 180ED @f2.8

Camera: Modified Atik 4021

Filter:  2inch Baader 7nm in EFW3

Mount: EQ6 with Rowan and EQ6 Wedge3 mods

P.S. Just seen this in Tom O'Donoghue's brilliant 25 pane mosaic in the top right hand corner.

Check out "CTB 1"

 

[Tom OD]

Yes Abell 85 or CBT1

[coatesg]

Yes CTB1. And the RA is pretty much bang on the zero line (good for triggering errors/bugs in software/mounts!)

Aha! Found it in the end 🙂

Thanks All, yes indeed it is CTB-1 (or Abel 85).

 When it was found, it was thought to be a Planetary Nebula, and given the label Abel 85. It has since been re-assessed and now is believed to be a Super Nova Remnant. It has also been given the name CTB-1 but has not been given a SN number and not logged into the list of Super Novas. Hence I couldn't find it!
