A coloured celestial donut, NGC 6337

[tornado33]

Hi all
Did NGC 6337. A ring shaped Planetary Nebula.
2x20 mins ISO 400, UHC-S filter used, modded 350D on 10 inch F5.6 Newtonian. Ive imaged it in the past with my unmodded 300D, but the modded camera shows the reddish flecks in the ring, obviously areas of Ha emission. This is a full res. crop of the centre of the image. Seeing was good, no wind, and the drive was running well. Hand guided with off axis guider, and object near zenith. I can separate the line of stars inside the ring, which indicates focus and guiding was ok

I havent taken darks for last few imaging sessions now, as ive settled on using 20 minute ISO 400 shots and so use some darks I took a few weeks ago, Iris has an optomise function whith matches the darks irrespective of the temperature they were taken.

Gee Scott, that is a very impressive image, or should I really say a very impressive capture. Well done, you are a very focused and determined person to hand guide in this era of auto guiding - I take my hat off to you!

Remarkable details inside the ring as you describe.

Cheers

Well done Scott!
You do have to admire anyone guiding for 20 minutes...I hardly have the attention span to keep an eye on the autoguiding I'm learning to do with Guidedog!
nicely done
keep 'em komin'

wow another obscure planetary to add to the bag..the line of stars you mention are they foreground stars or associated with the neb?

on another subject this optimise function in IRIS-how does this work? sounds very useful

great stuff Scott - NGC 6337 is one of my favourite visual donuts.
