Antares A and B with DSLR and Dobsonian

[von Tom]

Last night's seeing in Brisbane was quite good, and usually I just do the planets but I thought I'd give Antares a go using a Canon EOS 600D on video crop mode at prime focus of a 12" SkyWatcher Goto Dobsonian manually tracked.

I must admit that I was looking for a green star but could only see this slight blue protusion in the video, but unfortunately right along the atmospheric chromatic dispersion axis where the colour blue spreads to. RGB correction removed all doubt for me and I'm happy it's a blue star :)

This is from about 1000 frames stacked in Registax and unsharp mask.

Thanks for looking.

A good result there Tom. I managed to split them some years ago with a 6" refractor in nice seeing but I've lost the image now. A good excuse to do it again.

Nice work, Tom! Were you able to see the split in LiveView?

Nice one!, I tried bout a year back to split them in my 14" but the seeing was bit bleh, will have to have another go for sure now...once the cloud and wind get lost :)
