Rosette Nebula in HST palette

Paramount · #1 14-01-2014, 03:17 AM

Hi
This has taken a while to do because of the current storm system that has been affecting the UK. It was taken over 5 nights over the last six weeks or so and consists of 24x10 minutes Ha, 18x10 minutes OIII and 24x10 minutes SII taken with the Televue NP127is/FLI imaging system that I've been testing. The SII and half of the OIII was taken under far from ideal conditions with a three quarter moon close by and some thin mist towards the end of the session. The system is mounted on my Paramount ME with auto guiding taken care of by an Officine Stellare Falco guide scope and Starlight Xpress lodestar with dithering.
I have had a few goes at this in the past in both Ha and colour, these can be seen on my website http://www.imagingtheheavens.co.uk

Thanks for looking
Best wishes

Excellent image!
I think that's the nicest I've seen of that in SHO

Thanks for the comments, the focal length of the NP127 is its native focal length of 660mm, it hasn't been reduced. Bear in mind that the 16803 has a very large sensor chip and that contributes to the large FOV
