Hi again Dennis,
Thanks for the info, all is welcome and I have no problems with any comment, we are all here to learn and understand, if I'm mistaken, well, I will learn from the mistake.
I myself am a member of AAQ and have posted this image there as well. David Odriscoll replied soon after and advised me that you know your stuff ......
.
He also recommended that I keep more accurate records which I thouroughly agree with....still learning the ins and outs of this wonderful Science even at the age of 52.
He feels that the best judge of the image would be Jonathan Bradshaw who has previously imaged this split last year.
I will still try and work the field of view out at the time of the shot, hopefully I will get an accurate idea of the seperation in the image. If it turns out not to be the split I was hoping on then I will try again.
But just a piece of interesting info on my first split of last year of Sirius. I was using both a 150mm Reflector and a Meade 8" LX10. I could not see the split in the Meade LX10 because of the bright defraction rings that you get in excellent seeing, the pup was totally washed out by the rings, but in my reflector I had deliberately turned the tube so that the spikes where not in the apparent position of the pup and not cover it, I feel this was one of the main reasons I was able to get the split besides the excellent seeing condition at the time. I found out this method from one of the issues of Aus Sky & Telescope last year when they had an article on how to split
Sirius, not to sure what issue? It was implied in the article that a 150mm scope should have no problems spliting it but it was the brightness of the primary that made the split extremely hard.
I helped with the resolution survey that Tim Munn of the AAQ last year conducted on double stars, and I did split a few that I should, by rights, have been extremely hard with the 150mm but not impossible, a lot, as you know depends on the seeing and the colmination of your scope, I keep my 150mm extremely tight in the colmination area, and check it every night before use. So far I have not had the seeing conditions like the ones I did when I splt Sirius, the condition where unbelievably still and clear, and amazing.
Once I work the field of view out I will post the results here under this post.
