Title: Nov DSC Horsehead
Post by: MarkS on Nov 07, 2010, 18:25:12
Horsehead from DSC.

6 x 5min  Modified Canon EOS 350D on Bananascope (Tak Epsilon 180ED) with Astronomik CLS filter.  Grabbed in a gap between the clouds.

As you can see, the conditions were murky but I think this could be a fantastic shot with more favourable skies and many more subs.

That's really amazing Mark but you have a serious ring around Alnitak - I guess you processed for the nebulosity and the CLS probably didn't help too much either.

I think there's going to be a glut of these over the winter, that is, if we ever get any clear skies !!!

Really nice image Mark despite the conditions. The colours look a little weird to me though. The blues look too green.

Do you think it was the severe dew that affects the large stars?

I want to focus on Orion this year. Last year the weather was so bad I never got to do anything!

You'll find it's best to focus on whatever you're imaging, not just Orion.  Could be where you've been going wrong ;)

Hi,

Hats off to you Mark a) for going there this weekend and b) for a lovely image.

You can see the stars are bloated due to the cloud or mist, but even so its a fantastic photo, wonder how good it would be with a nights imaging in clear skies.

I must admit, I really don't want you to get a cooled colour CCD, or you will get really annoying :-)

Great imaging, this one goes in the extreme imaging calendar.

Mark,

I think you'll have to start writing a book of your exploits, call it 'Imaging Fever' !  I have 'Carp Fever' if you need a template...

Great image Mark, and again you have pulled it off. Well done.

With the issue of the misty conditions, I would suggest that to stick to cereal at camp, and leave the fry ups until you get home, or reposition your scope away from cooker, as with that amount that you was cooking I not surprised it was murky. :)

As a test image it is OK but it has a very "car headlamps in the fog" look!  I guess this was due to the milky conditions.  Maybe there was condensation on the surface of one of the components of the imaging train.  There was some haze on the image I took of the scope, table and French drink even though I could see no obvious condensation on the lens.
