M83

[bluescope]

Hi All

I haven't been doing any astro imaging for quite a while ... too much smoke around with all the farmers burning off when I felt like it and then too slack at other times :lol:

Anyway, I got myself out to the obs last night for a few hours and imaged m83 for an hour before I could smell the ominous odour of distant grass fire. I'm sure there would have been a fair bit of smoke in the atmosphere anyway from earlier but I was determined to get out.

So here is last nights effort.

12x300sec @ -10C
WO FLT 110 Triplet
SBIG ST2000XCM
EQ6 self guided with CCDOPs
stacked in DSS - final processing PS CS3

Your stars look nice and round to me, but I there is inconsistency in the colour through the arms of the galaxy - I was wondering if this was a problem of misaligned RBG frames, but then I see you are using a OSC camera. What does the original file look like - is this a problem of compressing the file too much to fit within the 200Kb limit for IIS?

This is the way it came out David ... I did say that there was smoke in the atmosphere ... it would have effected the colour somewhat ... although colour is always subjective. The original of any astro image looks a lot different to the finished pic ... but I didn't mess with this much at all really and I'm very rarely completely satisfied with any image.

Thanks for looking and commenting ;)

Good effort Steve under smokey skies damn CALM at this time of the year when we had a run of clear skies

Nice image Steve, Bummer about the smoke. It makes it hard to get a sharp image.

It's not just CALM Trevor it's the farmers burning off ready to seed their crops when the rain hits :shrug: I daily see smoke plumes to the East of my home deeper into the wheatbelt ... nothing we can do about it ofcourse ... we like to eat ay !

Cheers :thumbsup:



Yeah Doug it sucks but I had fun getting out in the observatory anyway.

pity i think you were affected by the smoke - nice shape!

Thanks Dave, I think the outer extensions are pretty well defined despite the poor overall image quality ... there's always another night ! We had some rain yesterday so hopefully they wil stop lighting fires soon ;)

Good to see you back, it's been a while.
The image is nice but as you say it's hard to get good data with all this smoke around.
There was a fair bit of smoke around at my place too the last few nights.

At least you were out there enjoying the night.
I find the longer I'm away from imaging, the more I forget things and the longer it takes to get back into the swing of things.

Hope we get some clear nights again soon.
