This week we feature the Propus region of Gemini which of course contains the well-known Jellyfish nebula, and if your field of view is big enough, the Monkeyhead nebula and open cluster M35 (and neighbouring open cluster NGC2158) as well. … Continue reading
Imagine you are a photon. You suddenly come into existence, and without the passing of any time, and without travelling any distance, you suddenly disappear again. Did you even exist? Well you must have done because an astrophotographer on planet … Continue reading
I just combined last night’s 24 x 5-minute subs 200mm lens single framer with an older 40 x 5-minute subs 2-framer also using the 200mm lenses. This is the resulting Arcturus composite.
Managed to get some imaging done last night. Arcturus with the 200mm lenses and 2600MC Pro CMOS cameras. 24 x 5-minute subs. Note the “Napoleon’s Hat” asterism at the bottom of the lower spike slightly to the right.
This week we feature the whole of Canis Minor, which is fortunately only 2 stars, but they are quite well separated. The 200mm lenses are of short enough focal length to capture both in the frame. There are only a … Continue reading
This is everything I have on Markarian’s Chain from the original Hyperstar, the Hyperstar III, the Hyperstar 4, and the Sky90 array. Must be more than 20-hours in total, probably more than 30. So why doesn’t it look a lot … Continue reading
This week we feature the huge Ha region in Cepheus designated IC1396. This is a 2-frame mosaic using a single Sky90 and M25C OSC CCD. Comprising RGB, narrowband Ha and narrowband OIII, this took the record for the longest total … Continue reading
The collimation was quite a way out when I imaged the Leo Trio 2 nights ago, so last night I was expecting to spend the whole evening trying to get good collimation. In preparation for this I had taken off … Continue reading
IMAGING!!!!!Collimation was well out on the Hyperstar and I thought it was going to take all night to get good collimation. First tweak on the collimation adjuster and I hit perfect collimation – took all of 2 minutes. So I … Continue reading
It was clear last night with a thin crecent Moon about to set, so I fired up the Hyperstar 4 on the C11. Target the Leo Trio. 4-minute subs with a 1-minute dither so I was planning on getting 15 … Continue reading
