From the Butterfly to the Tulip via the Crescent
Last night I got 11 x 20-minute subs using the 200mm lenses and the 2600MC Pro CMOS cameras with the Optolong L-Enhance filters – under a blazing Moon!!! I added the narrowband data to the 20 x 15-minute subs of … Continue reading
From the Buttertfly to the Crescent to the Tulip
Clear Moonless night last night and I put the 200mm lenses onto the Crescent region in Cygnus. Made the same old mistake in doing this, I should’ve put the Optolong L-Enhance filters on for this one. Never mind, I’ll do … Continue reading
The Coathanger Cluster in Perspective
An unexpected clear night last night left me unprepared for a new object. So I went for the Coathanger cluster, but centralised on the 200mm lenses. A total of 30 x 10-minute subs.
Third Frame of the Sagitta Mosaic
It was a clear night last night (after a day of rain!) albeit with an intrusive Moon, but that doesn’t prevent me from getting on with star shots. I managed to get the 3rd frame (the far right hand frame) … Continue reading
The Stars Like Dust
It really is hard to get a perspective on just how many stars there are in the Milky Way region of the Sagitta image. So I took a BIG crop out of the bottom of the image and magnified it … Continue reading
Sagitta
Managed to get the left frame of the Sagitta mosaic last night with anothe 5-hours of 10-minute subs using the 200mm lenses and the 2600MC Pro OSC CMOS cameras. So that is the whole of Sagitta covered. Apart from the … Continue reading
Sagitta Central
A clear beautiful Moonless night last night, one of the best I’ve seen in a long while. Target – the constellation Sagitta. This is planned to be a 3-frame mosaic with the 200mm lenses and the 2600MC Pro CMOS cameras. … Continue reading
Corona Borealis. A 10-year Project Finally Completed
Last night (staying up until 3 a.m.) I was able to get the 3rd and final frame of this 3-frame mosaic of the whole of Corona Borealis. I first had the idea to capture this one a decade ago, but … Continue reading
Spica Deep Down in the Murk
Unbelievably it was actually clear last night AND there was no Moon. Choice was between Arcturus and Spica, and as I’d only done Spica once before with the Sky90 array, Spica won. Just as with the Sky90 array image, Spica … Continue reading
An Altair/Barnard’s “E” Composite
Using Registar I combined the Altair/Barnard’s “E” images taken with the Canon 5D MkII and a 200mm lens together with the ASI 2600MC Pro CMOS cameras and the 200mm lenses. This is the result.
