help with Identifying a nebula in Orion was created by ftodonoghue

Hi Folks.

Was out observing in kerry tonight with Michael Scully. We were looking at clusters and nebulae in the region around M35 when mike stumbled on to a nebulous region which I have highlighted below. this was easily seen in 10X50's and the scope and was quite extensive(perhaps 1/3 degree in diameter from what I remember). I cannot find anything that matches its size in cartes du ciel or my charts and cannot figure out what it is. anyone have any ideas/
There are two nebulae in the region, Ced 62 and NGC2163, both of which are v small at around 2-3 arc minutes. and some believe are the same object.

Anyone have any ideas what we were looking at. or can anyone point me in the direction of photographic plates of this region. Thanks in advance

Cheers

Trevor - TheSky shows NGC2163 in that location. There seems to be a mark within your hihlighted boundary on the graphic you posted.

There is also another nebulae noted about 20 minutes away called SAC Ced 62 (from the Saguaro astronomy Club Database).

I would say that it is LBN858 and IC2162.

So many different objects in the one tiny area of sky!

I wonder what the 'official' designation would be? The NGC number?

Trebor - I found a nice image of NGC2163. Does it look similar to what you saw?

Cheers

Thanks for all the responses lads. I dont think it was ced 62 or NGC 2163 as they are too small to account for the size of the nebulosity visible. the nebulosity was about 20-30 arc minutes with Ced 62 and NGC 2163 being 2-3 arc minutes. Mybe there is further nebulosity surrounding both ced62 and NGC2163.

I did not take as much notes on the region as I should have done to make identification easier. That said, it was very easy in the 10X50's (from a dark site) so I presumed it would be on cartes du ciel. (maybe I am missing catalogues)

It could be IC2162 as this is 15 arcminutes in Diameter but I think it is a little too east from where I was looking. Ced 62 and 2163 seem to be in correct location...

Kieran do you have more info on LBN858...

Nothing for it but to have another look when it clears again.

Thanks lads.
Cheers

just afterdoing some more research. It seems this area is notorious for confusion.

According to
www.seds.org/~spider/ngc/revngcic.cgi?NGC2163

2163 has been cross confused with CED 62, DG 87, LBN 855, bipolar nebula in the past.

There is also another german article dealing with it here
www.klima-luft.de/steinicke/Artikel/n2163/n2163.htm

I also added more catalogues to CDC and there is a bright nebula LBN 855 also in the area. Perhaps it is the combined light of a number of different objects we were seeing. Will have to double check
Cheers
