This is my favourite Carbon star image, one reason being that there are 2 Carbon stars in a beautiful H-alpha setting, both in the constellation Cygnus. This is a 2-frame horizontal mosaic taken with the Hyperstar III and M25C OSC … Continue reading
This week we feature Bellatrix in the constellation Orion, but this a 2-frame mosaic for a reason. On the right hand side of the image, all the “brown stars” are in fact a bunch of faint fuzzies – a very … Continue reading
This week features a composite image of the Pickering’s Triangle region of the Veil nebula in the constellation Cygnus. This is a composite Hyperstar image taken using the original Hyperstar as well as the Hyperstar III and Hyperstar 4. Many … Continue reading
This week we feature the beautiful Pac Man nebula and nearby main star Schedar in the constellation Cassiopeia. This image comprises many hours (well over 8) of 15-minute subs taken with the Sky90 array and the M26C OSC CCDs.
This week we feature the whole of the constellation Sagitta, together with nearby asterism the Coathanger cluster. This is a 3-frame mosaic taken using the 200mm lenses and ASI 2600MC Pro OSC CMOS cameras. UV/IR filter only (RGB data only) … Continue reading
This week’s image is a real blast from the past! This is the Flaming Star nebula in Auriga taken with the original Hyperstar (no collimation or rotation adjusters) and a tiny little H9C OSC CCD. That really was a very … Continue reading
This week we feature a very recent composite image of the Crescent nebula region in Cygnus. The data comprises 8 hours and 40-minutes total exposure time using UV/IR cut filters (for RGB data) and Optolong L-Enhance filters (for narrowband H-alpha … Continue reading
This week features a rare (for me) 4-framer with the 200mm lenses. This is the whole of the inner part of the constellation Lyra featuring Vega. This was taken using the M26C OSC CCDs and I would like to redo … Continue reading
A recently acquired image is this week’s Picture of the Week. Today we feature the whole of the constellation Sagitta. This is a 2-frame mosaic using the Canon 200mm prime lenses and the 2600MC Pro OSC CMOS cameras on the … Continue reading
A blast from the past for this week’s Picture of the Week. Today we feature the Coma cluster of galaxies made famous by Fritz Zwicky who applied the virial theorem to star motions in these galaxies to deduce that there … Continue reading
