NGC 5844, Planetary Nebula in Triangulum Australe

[tornado33]

Hi all
In what would normally be a pointless exercise, I had a go at some deep sky imaging tonight, despite the 2/3 full moon.

I used the Baader UHCS filter, and a 5 min ISO 1600, and then a 1/2 hour ISO 400shot, stacked in Photoshop, of this dumbell like planetary. No dark subtraction done, I dont seem to get noisy pixels when extracting the raw Canon images with photoshop CS, just the amp glow which can be cropped out for small objects like this or removed with Gradient Xterminator. I cant wait to try for this object again under moonless skies. I had a pretty good guidestar, wasn't too hard off axis hand guiding for a full 1/2 hour, but then the wind came up again, putting paid to any more shots of it or anything else tonight.
Kudos for Houghy mentioning the gas lift bar stools on sale at the Reject shop, I got one and its great for allowing me to guide whilst seated (much easier)

Hi Scott
Tried that link & got a blank page ?

The site is proving a bit unreliable, try this link

Yep... thats better !
Nice shot Scott, how does it look visually ?
I was reading Deep sky delights in the July AST, there are some interesting DSO's in APUS, just below Triangulum Australe.

Hey Scott,

You are indeed the king of the obscure and lost!!!! Well done!

Mate it is a wonderful shot under duress. Now do the same shot right at full moon and see what the difference

Thanks all.
I confess I havent see it visually but heres a DSS image of it

half an hour under bright moonlight...who would have thought it possible

nice catch

BTW I aquired a LP filter (Astronomik) last week myself and had a go on saturday ..kept each sub to under 10 minutes though..havent downloaded any images yet from camera, but looks promising

scott yours looks much better

thanks houghy
Seeker, Id be keen to see some of your filtered pics
I got to use an Astronomik CLS filter at the Kulnura Ice in Space night, it looked like a good filter, less severe on non nebulous objects than the Baader one. The CLS may be good for galaxies, I dont think the Baader one is.
