Thanks all for your nice comments.
Robby,
This was taken with a 4" Takahashi FS102. I made up a set of cross hair type vanes out of aluminum and painted them flat black with felt on the ends. They just slide into the dew shield.
If I wanted the same effect on my 9.25 I would use a set of very thin black shoe laces and blue tak them across the front.
The detail in this structure is hard to bring out with only 4" of glass. I will do this again on my C925 in a couple of weeks when I am at Vic South and hopefully get some of the nodules that are in the inner ring....
Processign from a dark site will be a lot easier. A full moon and wide field with the Tak makes Light pollution gradients a nightmare....from the burbs
Best Regards
Chris
