Howdy
Here is planetary nebula Shapley 1 (Sp1) and the much fainter VBRC7, in H alpha
3x 10 mins ISO 1600, 4 Nb Baader H.a filter, modded 350D camera, 10 inch F5.6 scope, moonlit skies. Darks flat and offset processed in IRIS. Blue and green channels discarded in Photoshop, red converted to monochrome.

It never ceases to amaze me we can see objects so far away let alone image them. You really push the limits though Scott. Two very nice planetaries. I wonder if the putative inhabitants of their planets agree as their 'sun' started behaving most erratically.

Thanks Bert, yes I love Planetaries as no two are the same, and in the timeline of the galaxy, they are fleeting occurrances, gone in a flash. We only need to wait a few billion years and the Son might give us a nice planetary nebula (would be interesting to see what particular type of Planetary the sun produces).

I look forward to visualy seeing Sp1 when the moon gets out of the way

Scott, Great images,

I've been after Shapely 1 the last two w/e's, with no success. My next new moon will be down in Goulburn with my club at the Magellan Observatory. With the darker skies I hope to see it in my 12".

Thanks people. Indeed I hear SP1 is a challenging object to see, I confess Ive never seen it visually myself. I wont even think of trying for VBRC7 lol.

A fantastic image, tornado33.

I find it interesting to note that the central star of Shapley 1 (Sp1) seems to be quite apparent while the VBRC7 parent is missing (unless it's the star at "11 o'clock" zipping out of its own debris).

Thanks.
The parent star of VBRC7 may be very faint. Theres a hint of it in my colour image, but its more easily seen in the ultra deep UKST H a survey image Ive also attached, though even then its rather faint. It musnt emit much H alpha light, Im wondering if its because it blew all of its hydrogen away?

Wow that VBRC7 is darn faint. Thanks for showing it to us.

Shapley 1 looks marvellous - not sure that I've seen a better amateur image of it before.

Thanks Paul. Mind you finding them, and composing the picture correctly is made so much easier with a star chart generated from from Star Atlas pro
