Noel Carboni just processed this earlier Hyperstar III data of the globular cluster M56 almost lost in a rich Milky Way background star field.
The same night I got the California nebula data with the mini-WASP array, I also got some earlier Double Cluster data with the array, and, some M33 deep data with the Hyperstar III. The Hyperstar was using 20-minute … Continue reading
Nice clear night (so far) tonight and I have both the mini-WASP array and the Hyperstar III grabbing data. Took one of two frames with the mini-WASP and then moved onto the California nebula for some half-hour subs (that’ll be … Continue reading
And here is an 8 x 5-minute test shot of the Ruchbah region taken with the TS 80. Hot pixels aplenty, but star quality as you can see very good considering the chip wasn’t even flat!
I have returned the faithful old M25C to the Hyperstar and taken the new M26C into the mini-WASP observatory (North dome) awaiting the arrival of the TS 80mm triplet APO. Expect rain and cloud for at least the next 6 … Continue reading
And here’s that recent Kappa Cassiopeia data expertly processed by Noel Carboni.
Whilst working on the mini-WASP array last night I took a quick image of a reasonably bright star with the one good scope and camera. The central star is Kappa Cassiopeia and the two open clusters above it are NGC … Continue reading

Whereas there are lots of very red stars in the night sky (not many bright ones though) there are fewer very blue stars, that is stars with a big negative B-V index. The brightest very blue star in the night … Continue reading
