Hi Rod
Well, I’m now left wondering if I have been going down the wrong path after seeing yours and Jonathan’s images?
I chose to use a x4 PowerMate to give me a longer effective focal length to provide a "greater" separation between Sirius A & B, based on the much increased image scale. This approach has certainly recorded the Pup as a much dimmer object in my images so I’ll attempt the split gain, but at the native focal length of 2160mm of my Mewlon 180 and see what I get.
This has been a very insightful and enjoyable investigation and discussion – thanks! I might even break out the 4” Vixen and give it a go with that, as I have successfully split Antares visually and using my Meade LPI with the 102mm aperture.
So many projects, so little time…sigh.
Cheers
Dennis
