Horsehead Nebula 27-11-11

[Carole]

Taken from my Back Garden (POD) early hours of 28th.

29 x 5mins 800 ISO, CLS filter, Modified Canon 450D
Skywatcher ED120 Pro, Guided with ST80 and PHD
+ darks, Flats and Bias
Stacked in DSS and post processed in Photoshop CS3
Full Frame
Could do with a few more hours, but was quite pleased with it considering the location.
Hoping to add to it.

Well that looks good Carole, come out well

I was heading that way but got fed up with next doors trees. Will have to set up elsewhere in the garden

You must have had a late night - I was also out last night - imaging until 6am.

I think that is an excellent result for a CLS filter from a light polluted area like yours.  The Horsehead itself has come out very well indeed.

The Flame has a weird colour cast though and the areas of nebulosity below the Horsehead should look a bit bluer.

These are only minor criticisms for an otherwise good result.

Thanks Fay.

Hi Mark,

You must have had a late night

I was up until 3.45, and then went to sleep while my darks were capturing.  

The Flame has a weird colour cast though and the areas of nebulosity below the Horsehead should look a bit bluer.

Yes I thought overall it was all a bit too red, but the colour channels seem to be fairly even, so I decided to wait and see what feedback I got.  I'll have a further tweak and see what I come up with.

I was quite pleased with Alnitak this time as it was really blown out when I did this a year ago.

I think that's a great result Carole, the colour cast will be difficult to control but non the less I think you've processed it very well.  Stars look good and there's a bit of underlying noise that a few more subs would help with - apart from that it could be one of your best to date !

Thanks Robert.

a bit of underlying noise that a few more subs would help with

Yes I am hoping to do at least the same amount again.
