Hi
This is my first attempt at doing a mosaic and this has taken a month to shoot all the data because of work and weather. It was taken with the Televue NP127/FLI prototype astrograph which I have been testing (and I am glad to say I am keeping). This is on my Paramount ME and auto guiding was done by a lodestar with dithering. As an experimentation I tried various ways of stitching the two panes together and found that out of Photoshop, Maxim DL and a freeware programme called Microsoft ICE the latter was the easier to use and did the best job.
Exposure times are as follows for each of the two panes
20x10 minutes Ha
24x10 minutes OIII
24x10 minutes SII
The colour scheme may be a bit different to how others do the HST palette but there is no clear defined rules for the colours so this is my interpretation.
A larger version can be seen at the following link
