[...] I look forward to collecting more exposures & thereby improving upon these images. In the meantime you can see more of Orion by viewing my earlier adventures with Orion. [...]

Excellent views of Alnitak, Alnilam & Mintaka.
But what is the distance between them.
I have always wondered when i view them in the sky at night.
A truly amazing site.

Marvellous.
Dark skies here in W Devon make viewing rewarding (assisted by Arab horses)
My electronics interest has taken me to EX mil image intensifiers coupled to old 8 in mirror.
125mm telephoto coupled to intensifier improves over naked eye but not a lot so some way to go.Just starting

The horsehead photo was spectacular. That calls for wall size format and display. Thanks for sharing and your interesting text. I’m currently viewing Holmes Comet here on the Big Island of Hawaii. Excellent dark tropical nights, especially during New Moon.

Hello Paul,

My images are all with DSLR so I’m no expert on seperate colour CCD imaging. What I would say is get plenty of exposure time – it makes processing a happier business & the result will be smoother & more detailed. Also and particularly for the horsehead region, pick-up some H-alpha exposures and either blend with the Red or use as Luminance channel – this will help display the background nebulosity.

Exposure time – many CCD imagers seem to give most time to Luminance / H-alpha with just enough RGB to pick up the colours.

Have a look at Rob Gendler’s CCD image at http://www.robgendlerastropics.com/HH11Kpage.html
it uses 75% H-alpha.

Good Luck
AnnMarie

AnnMarie – very nice – i plan to image M78, 2024 and maybe horsehead this year (kinda tired of M42)

can you recommend special filtering, exposure time in each channel or any other tricks to image these objects. my imaging scope is a 5″ apo, guided. i have a color and mono ccd cams well matched to the 5″ apo. i just acquired a set of para focal LRGB filters. I am a communityobservatory.com docent

thanks, paul

Hello Dave,

Thankyou very much for the kind comments.
I’ve just been looking at your Barnard’s Loop picture, very impressive & with a medium format film camera too.

Thanks again,
AnnMarie
