Hmm .. I notice the astronomers are dressed quite "formally" ..

Long pants and shirt .. Wow!! Like some kinda business meeting ..

In SG, all the obs I've been too so far, everyone was in shorts/bermudas and T-shirt .. HAHA ..

that's because everyone went straight from their office to the ob location, on the rooftop of one of the university buildings.

The report was lost during the server downtime, i'm too lazy to rewrite.

In short, the two scopes provides great contrast with black velvet sky background, probably the best instrument to split binaries. In term of resolution, they behaved according to the laws of physics, roughly comparable to a great 7" and 8" newtonian, for the TEC and the AP respectively, in terms of what it could actually show.

Many thanks again to Anat for hosting this last minute ob!

cheers,
Arief

Hi, Arief
Please try Sirius as well, I've been waiting to split the difficult pair for a long time.
Tried with Mewlon 210 at 300X magnification last month but still got no successful result.

Would masking the parent star on the eyepiece help? Anyone try before?
