LX90 8"/Baader Alan Gee II Telecompressor/Canon 350Da/Astro Photo Tool, HEQ5 GEM/EQASCOM/Cartes de Ciel, QHY5/Finderscope/PHD.

12x300s ISO800 processed in Deep Sky Stacker, 10 darks and 7 flats. The darks don't sem to have enabled DSS to remove the amp glow bottom right. Any ideas? Also I've just noticed the satellite trail!

Reprocessed removing sub where guiding had glitched. Set Dark multiplication factor to 3.0 under Settings... and this seems to have cured the amp glow and the flats not being applied ( :bug: ?). Also tweaked the stretching and colour balance in DSS.

That's looking good Duncan.  Not tried this one yet, looks like it will need another hour or more.

Glad to see some imaging got done at DSC.

I don't think it's amp glow.

Nice work, I think the background could do with being a tad darker and you have a black splodge top right

Looking good Duncan!

The bright patch is definitely 350D amp glow. Are you absolutely sure the darks have been subtracted - it really doesn't look like it to me.

Very good Duncan!
I saw that sub with the satellite trail down load on your laptop.

That's not at all bad Dunc - Some of the wispy blue/purple stuff in the middle is starting to show through. still looks like you have some minor collimation &/or flattener issues though..

Nice image - John

Ha! Looks like the flats weren't subtracted either. What is DSS doing??? I will have a check of all settings.

Duncan,

You've removed the link to the original, so it's difficult to see the comparison.  However, there is a dark patch where the usual amp glow bright spot should be.  This might indicate that too much dark has been subtracted (3x too much?).  There is also a strange noise pattern across the whole image which might indicate the same thing.  Or was it on the original as well?

 :alien: :BTW the host server (POWWEB) seems to be having an attack of the porn site search pages and I think this is stopping my images being visible. :roll:

Are both images linked to in this thread?
