  1. From the album: Planetary work

    This is a re-processed set of 159 images taken from a few years ago. Each image was generated from a 3 minute video. It shows Europa passing across the face of Jupiter casting it's shadow across the northern hemisphere. Telescope: Skymax 150 Maksutov with a TeleVue 2x Barlow lens and a Baader fringe killer filter. Camera: Canon 550D in 640x480 crop mode. ISO Auto at 1/60s exposure. Processing: Quality filtering and centring done using Pipp, stacking and wavelets processing done using Registax 6.

  2. From the album: Mars

    Having messed about with one of my blurry images of Mars for most of the afternoon, I may have captured the clouds over Olympus Mons or otherwise I've managed to organize 'noise' into a clump.

  3. From the album: Lunar

    Arzachel, Alphonsus and Ptolemaeus It feels like I have been back to basics this week with imaging, exploring sharpening options. I think I will process a few more lunar shots to help get a new sharpening process going. This was sharpened using Astra Image. --- 01/01/2016 Celestron Edge 8, ZWO ASI174

  5. From the album: Mars

    Night of the 9th October 2020. A clear night but unfortunately the Jet stream conspired to make images wobble like jelly on a plate! A stack of 9mins of RAW video clips. 127mm Meade Apo Refractor with 3x Barlow and QHY5-11 colour planetary camera. The best of a poor set of clips.

  13. From the album: The Moon

    Last night was surprisingly clear in between the increasingly wet and windy weather fronts. After taking some video clips of Mars I pointed my 127mm Refractor at the Moon. Look as I might I could not see any fresh water lakes in Clavius.

  17. From the album: Deep Sky III

    NGC4725 is the brightest member of a galaxy group in the constellation Coma Berenices and is about 40million light years distant and 130,000 light years in diameter. The structure is somewhat unusual, consisting of just one spiral arm which is tightly wound around the core and can be followed for about 1.5 revolutions. The spiral arm consists of dust and gases including bright blue stars and pinkish Ha regions which indicate star forming regions. Towards the center, much older, yellow stars can be seen. The galaxy is classified as a Seyfert Galaxy, indicating that the center contains a superma

  20. From the album: Deep Sky III

    Located in the constellation Bootes, approximately 52000 light years from Earth, lies the globular cluster NGC 5466. It is designated as a class XII cluster, meaning that it has relatively non-concentrated stars towards the core compared to a class I cluster. This last fact starting me wondering if my scope would be able to resolve the "gaps" in the central core...... note also the various background galaxies. The LRGB image below was taken with my Esprit 150 and represents just over 9 hours integration time.

  21. From the album: Photos from Bury

    Date taken: 21 and 23 March 2020. Camera: Astro-Modified Canon 600D. Telescope: SW Esprit 100 with Field Flattener and Baader U-HCS filter. Mount: AZ-AQ6 mount Image: 60 light subs (3 minute with 15 sec interval) with master dark, Flat and bias each made from 80 subs. Comments: The Pinwheel Galaxy is a favourite goto object for me. There is good detail here but not quite beating my image obtained in Salisbury a few years ago. There is no substitute for a dark sky. The larger FoV of the Esprit 100 does capture the smaller galaxies in the background well though. I may try to add more subs to t

  24. From the album: Deep Sky III

    A second attempt at the Witch’s Broom Nebula (NGC6960), this time in narrowband. It took me 3.5 months to acquire the data, which was caused by a combination of poor UK weather and the partial obstruction by trees at my location. Although imaged in narrowband, I tried to go for realistic looking colours so started with Ha mapped to red and OIII mapped to blue with a synthetic green generated from a Ha/OIII mix. After a few hue adjustments, I ended up with a colour image which mainly gave blue/reddish stars and nebula. I found that detail could be boosted by creating a super luminance ima

    LBN 438 is a dusty nebula located in the Lacerta constellation which is also known as the sand worm (from the Dune science fiction series) or the shark nebula. It doesn’t appear very often on SGL, probably because it is so faint ! It is illuminated by interstellar radiation known as Extended Red Emission (ERE). ERE is a relatively recent discovery (1975) and is a photo-luminescence process whereby hydrogenated amorphous carbon is illuminated by interstellar photons in the 500 to 1000nm spectral range. Although the nebula also contains ionized hydrogen, it only emits a relatively weak

    It's by no means a prize winning image, but it's my first one except photos of the moon. I even got andromeda in there and that makes my tummy tingle! Unprocessed of course.

  32. From the album: Deep Sky III

    M94 is approximately 17 million light years distant and contains both inner and outer rings. Star formation occurs in both rings but is mainly concentrated in the inner ring which is also known as a starburst ring, within this region, the rate of star formation is occurring so fast that it will exhaust the available interstellar gas supply well before the death of the galaxy. The extensive outer ring contains about 20% of the galaxies mass and consists of spiral arms when viewed in IR/UV, however, in visible light it appears as a halo. Exactly how the outer ring formed is subject to debat

    This is a center crop of Sh2-308, AKA The Dolphin Head Nebula in the constellation "Canis Major". This was imaged through Baader 7.5nm HAlpha & OIII narrowband filters using my full spectrum modded and cooled Canon 40D DSLR and the Bosma 80mm refractor at 500mm focal length. This photo consists of 46x1200s of HII, 35x1200s and 2x600s of OIII and 36x60s, 32x150s and 21x210s of RGB subs @ ISO1600 for a total exposure time of 30.5 hours. This object is very weak in HAlpha signal but very strong in OIII. The benefit of a color camera is that I captured two spectra lines in one exposure, I ha
