Rosette Nebula HST palette

[Paramount]

Hi
I have been having problems with star trailing due to differential flexure which was more noticeable on the longer sub frames so I decided to try an OAG which along with the necessary adapters has arrived so last night I managed to put it to the test. I thought I'd try the Rosette Nebula and this is 6x20 minutes for Ha and OIII and 3x20 minutes for SII (a big oak tree about 40 yards away stopped further progress). Hopefully I will get some more data later on. The star trailing seems to have been resolved and the OAG was easy to set up as it has a helical focuser built in.
This was taken with the FSQ106 and H36 camera on a Paramount ME using 5nm NB filters. Dithering was used in the auto guiding. I have made several attempts at this object since I started imaging and these can be seen in the image gallery on my website http://www.imagingtheheavens.co.uk
Thanks for looking
Best wishes and clear skies

What can one say? Really tight image. The OAG seems to have worked! Wonderful depth and colours. :)
