These are the sort of objects I enjoy imaging the most. A "recently" discovered PN (1973), extremely faint, and very few references to it on the Internet let alone any images.

I like your tastes in objects, small and rarely imaged :thumbsup: I like similar, but err towards the galaxy variety :) I like your image. The stars are a little dominating, but the aesthetics aren't the point, it's getting that faint rarely seen object that is :thumbsup:

Thanks Roger.

These sort of objects are not processed as pretty images, only to be seen as clearly and as detailed as possible.
I have preference a for galaxies as well. Next season I might be mad enough to go after the Cetus Dwarf galaxy discovered in 1999.

An excellent capture Steven, that's what it's all about capturing the faint lesser known objects.

What magnitude is the PN?

Cheers

Thanks Ric.

It is a 13th magnitude planetary.

Fantastic image of an obscure planetary, excellent work Steve.

Nice one! I remember trying to track this down visually with friends of mine out at Coona' in the mid 90's under excellent conditions. Not an easy one to see. Cometary globules are anoher good challenge target for imaging and of course, there's the Abell catalogue.

Interesting target. Where is it?
All I could find was this
ASYMMETRICAL BUTTERFLY | 09:27:04 | -56:06:18 | PLANETARY | 11.8 | NGC2899 ;HARTUNG 388 & PICTURE PLATE 61;LOW SURFACE BRIGHTNESS USE OIII FILTER; DISCOVERED 1835 PN VBRC2 AKA SA3-10 IN SAME LOW POWER FIELD SEE SEPARATE NOTES

and this seems to have been discovered in 1835

It is "HARTUNG 392;IN SAME FIELD AS NGC 2899;USE OIII AS INVISIBLE WITHOUT IT; DISCOVERED IN 1973; FAINT HAZE 2 MIN ARC ACROSS" according to http://www.sas.org.au/Peter%20Marples/popular.htm
VBRC2 is 38' from N2899. Andrew James has some details on VBRC2 = SA3-10 at http://www.blackskies.org/nsp12.htm

Thanks Glenn
At ~38 acmin apart it should be reasonable to image both on the same pic. An interesting challenge.

Hi. Thanks Glenn.
Please find attached for the IIS'ers here a copy of the recent updated version of details on these objects in pdf (See attachment).
Love the picture, sjastro. Better than many of the images with larger telescopes that I've seen of the object. Congrats.

To all concerned thanks for the comments.

The coordinates for VBRC2 are RA 09 31.9, DEC -56 18.

I would have liked to include NGC 2899 in the image, the FOV of the BRC-250 and ST-10XME is limited to around 25 X 23 arcminutes.
