A few posts below I gave a procedure on collimating your imaging camera to a Hyperstar III. On reflection I thought that this could be considered as so much “hot air” without results to prove the procedure actually works. So … Continue reading
Here is second light for the 3 x Sky 90 mini-WASP parallel imaging array. This is open cluster NGC7789 near Caph in Cassiopeia. The image is 18 x 15-minute subs or a total data time of 4 and a half … Continue reading
On the evening of the 27th October 2014 I spent the first two hours of darkness aligning the 3 Sky 90s to look at the same region of sky, and then focus training Sky 90(2) and Sky 90(3). After the … Continue reading
On the evening of the 19th October I got a couple of clear hours before it clouded over. Enough time to set up the Hyperstar and get an hour (4 x 15-minute subs) on the California nebula. I had forgotten … Continue reading
The 3rd (and final) Sky 90 has been fitted to the mini-WASP array 🙂 I will now be able to get 12-hours of data at f#4.5 in a typical 4-hour imaging session. Provided that I get 4-hours of clear Moonless … Continue reading
It is possible to get perfect stars right across the diagonal of an APS-size chip such as the Starlight Xpress M25C or M26C – but only if your Hyperstar imaging system is in very good collimation. Getting good collimation is … Continue reading
I have completed the initial experiments with the Canon 200mm lens piggy-backed on the C11, so yesterday I removed the kludge on the back of the C11 and re-instated the Hyperstar III – just in time for all the winter … Continue reading
There are 5 very nice Carbon stars in Andromeda that I would like to bag this month and this is the first I’ve caught – UY Andromedae with some nice faint fuzzies, and a couple of not so faint fuzzies. … Continue reading
The mini-WASP array was again put into commission taking half hour subs of the Navi region of Cassiopeia – Navi is the central star in this image. Nearby lies Gamma Cassiopeiae and its associated nebulosity.
Several hour’s worth of half hour subs resulted in this deep view of the PacMan nebula and nearby bright star Schedar in Cassiopeia courtesy of the mini-WASP array. The array is due for an upgrade at the end of this … Continue reading
