Hi
I apologise for yet another picture of the Horse Head and Flame but it is one of the most photogenic sights in the night sky especially if you go deep. This is 6x20 minutes with an Astrodon 5nm Ha, Starlight Xpress H36 and FSQ106 on the Paramount ME, autoguiding was done with an H9 on a TMB115 with dithering. I am still having problems with what I think is flexure causing star trailing, this is more evident in the longer subframes and I will probably go down the OAG route which should resolve this issue. I find it is good to revisit subjects and this is one my first ones that I took 2 years ago. I also took an image of this last year but with 10 minute subs with the TMB with an unconventional palette of HaSIIOIII = RGB and I plan on doing the same with this subject this time round so this currently a work in progress. My earlier efforts can be seen on the nebulae page of the image gallery of my website http://www.imagingtheheavens.co.uk
Thanks for looking
Best wishes and Merry Christmas to all

I will definitely recommend using an OAG... I've been using one myself for quite a while now and love it... Especially if you're going to be guiding with something as sensitive as the SX H9.. Besides, The TMB-115 is probably a little bit too awesome to be used as a guide scope!
Lovely Image - hope to be able to do pics this good when I can get my telescope out on a cloudless night at a dark skies site!
All the best for the festive season.

Is there a larger image to look at, I would love to surf around it a bit better.
Great set of equipment you have for this too, I look forward to the final compilation.

Hi Mike
Thanks for the comments, there is a larger version on my other website http://www.pbase.com/imaging_the_heavens which is 1920 pixels wide, I only did it this large as it fitted perfectly on my monitor and the star trailing due to the differential flexure didn't appear too bad
Best wishes

Another super picture Gordon. Top work! 
Merry Xmas to you too and all the best for 2010.
