Observing Challenge STF216

Recommended Posts

This is an observing challenge for anyone with a large telescope. There is s tight double In Casseiopeia STF216. It is 0.3" apart. There is a provisional orbit. It will probably take at least a 14" scope to split but anyone is free to try. 

Please post your observations both positive and negative :)

cheers

Oh don’t do this to me, now you’ve got me all charged up, I’m a double famatic and am up for any challenge even if it is well beyond my scopes. My 128 is outside cooling, I will certainly strain my eyes to the point of myopia but it’s all worth it.

With smaller to medium apertures I reckon the challenge will be to see some signs of a deformity to the primary star airy disk at approximately the correct position angle. 

Rather like I managed to get with Dubhe a couple of years back. No split, just vague indications of a "bump" at one point in the primary star airy disk.

That looks tough, I've not clocked anything that close myself, but it's now on my hit list to try because why not.

I have a 14"" but I think this will also need good seeing, good eyesight, and good technique, which doesnt bode well for me!
