Sh2-308

Sharpless 2-308 is a bubble blown out by a star thought to be in it's pre-supernova phase.
I took this image through thin smoke and with a rising full moon, about 2.5 hours of 6 min exposures with the L-Enhance filter.
I hope to get quite a nice image under better conditions.

Amazing pic, particularly when taken at a full moon with smoke haze which exacerbates the light pollution effect !


Which telescope / lens did you use ?

Thanks everyone for the kind comments.
This was taken with the TS115 and 0.8 reducer. I've just received a Starizona Apex 0.65 reducer which will bring the f/7 scope to f/4.6 so I might try that next time, given the faintness of the bubble.

It's a fabulous object in nature and appearance - I'd really like to get a clear image.

Thanks Lost and Mike. We might still get lucky with the rain that's forecast dampening the fires down.

For anyone wondering how to find sh2-308 you can go-to the brightest star in the image, SAO 172542.

Had another go at this one last night with the Apex 0.65 reducer on the TS115 - the object exceeds my processing skills though - need to do some reading.

I now have gear that is beyond my ability ... But enjoy trying to get all I can out of it...anything at all is good..I am 73 and need a walking frame ..it is a challenge...and then you realise there is just so much more to learn..
I still don't 2 star align and find objects manually through a finder..I some how enjoy the challenge of finding simething...and those times you have trouble finding it for whatever reason.. mmm it should be here but it's not..I Remember those stars..??? And I guess I would prefer to move manually to save battery power ..actually main reason besides the earlier reflection. Comes from feeding torch batteries to my first eq mount..it started as a money thing but I just don't bother with Goto oddly.
My trouble is I do so much to get ahead of myself...still I am old I can't wait around...not much time left for doing this you could think.
Alex

Yeah it's all good fun Alex. I go in and out to the imaging rig and enjoy just sitting looking at the sky while I wait for an exposure to finish.

It's looking mostly clear tonight so I might try adding a few hours to the image, then hopefully have to stretch less.
