    This is the final animation made from 60 individual stacked images each made from 2 minutes of data taken duing the night of 13/14 March. The gap in the sequence was caused when my camera battery died. Recharging it took about 30 minutes. This took a lot of effort to process each image but it was well worth it. Strange to be converting the original video to a single frame, only to combine those frames to make a video... Scope: SW Skymax 150 F/D = 12 plus a 2x Televue Barlow giving an effective F/D ~ 24, I also used a Baader fringe killer. Camera: Canon 550D, 640X480 movie crop mode, ISO = 800, exposure = 1/60s. Processing: Each stacked image was made of 2 mins of video (7200 frames). The best 2000 frames were selected and decompressed in Pipp. These frames were sent to Registax where the were aligned using between 40 and 50 align points. The frames comprising the best 90% in quality were retained. The frames were stacked with 2x drizzle. RGB align corrected for residual CA, The first 3 wavelets were enhanced (interval = 1) and the gamma + colour balance were altered. Final gif frames were cropped and centred in Gimp and the gif was produced using the GNU/Linux convert command.

    From the album: Next Attempts at DSO's

    I have made a meandering 7-pane mosaic showing some of the many Sharpless objects in the area of Cepheus which stretches from the nebulosity near Mu Cephei to NGC 7822. Each pane involved 2 hours of 300s exposures taken with a modified Canon 700D DSLR, a clip in 12nm Astronomik Ha filter and 135mm Samyang lens at f/2. All the light frames were taken at ISO 400. Images were stacked in Deep Sky Stacker and further processed using StarTools. The images were taken over a period from May to September 2018.

    From the album: Beginnings

    Originally a test subject for my guiding issues, I collected about twelve hours of subs on this and thought I'd throw a few hours of the better ones together, total 3h 46m of 3m subs with 50 each of dark, flat and bias. My goal was to get both central stars noticeable to some degree and some detail in the ring, and this at least was accomplished.

    From the album: Deep Sky Imaging

    This is NGC 1097 which is a barred spiral galaxy about 45 million light years away in the constellation Fornax. This Galaxy is a interacting galaxy with obvious tidal debris and distortions caused by interaction with the companion galaxy NGC 1097A. This image was taken with a Canon 40D DSLR, using a 8" SCT telescope at 2032mm focal length on a CGEM mount. I imaged this across four nights, but unfortunately the last 3 imaging nights we had a bush fire about 50km away and the sky was a little smokey so the end results could be (and most likely was) effected by the smoke. There is no hint of any jets, and I was stretching the stacked data specifically looking for it, but nothing... it might have been blocked by the smoke or my 40D is simply not sensitive enough to pick it up, or both.

    From the album: Deep Sky II

    This image represents 18.5 hours of integration including 8 hours of Ha. It's quite an unusual image in the sense that the nebula and stars play an equally dominate role, particularly given the presence of some very bright stars. As a consequence I decided not to push the stars into the background. The Ha was mainly used to enhance the Luminance although I did add a little to the red channel. In an attempt to get accurate star colours I also attempted to blend RGB stars with the LblendRblendGB image. Colouring the nebula was the major challenge since some parts are quite bright (the "head") whilst other parts (eg the "legs") are quite faint.

    From the album: Deep Sky II

    I gave this quite a long exposure with the H alpha filter (c7.5 hours) since I wanted to capture the various hydrogen clouds. The image represents about 15 hours of integration. CCDstack used for calibration, stacking and error rejection. Pixinsight for DBE, BN and Colour Calibration, PS for everything else. The major challenge with this image is that it contained various scattered light "rainbows" that where generated by out of view bright stars, one of these "rainbows" passed straight through the galaxy. To eliminate the scattered light issue I followed the PS tutorial by Adam Block in his "cosmic canvas" series - this is an amazingly effective technique to eliminate/reduce the problem. LIGHTS: L:15, R:9, G:10, B: 12 x 600s; H: 15 x 1800s. DARKS:30; BIAS:100; FLATS:40 all at -20C.

    With 3 different sub lengths used on this object I thought I'd re-process to see if I could get more detail in the core region. Whichever way I blended the sets I always ended up with pretty similar results, so I reckon this is the definitive version, about the best that I can achieve with the data available. If nothing else I'm pleased to have been able to have made the just resolved Trapezium better defined. This image is comprised of 103 x 30s subs and 176 x 10s subs taken 28 Dec 2016, blended with 191 x 2s subs, taken 4 Jan 2017. Subs were stacked with AstroArt, and both sets processed in StarTools without using the colour module. Blending was carried out in PWPro and final tweaking in Lightroom. Equipment: Fuji X-T1 through an Altair 102mm f/7 Super ED with a TS Photoline 2" 0.79x reducer/flattener. Mounted on a Nexstar 6/8SE Alt-Az mount.

    Third attempt at M31 and my second reprocessing attempt. After watching Adam Block's excellent PS tutorial (Cosmic Canvas) I decided to incorporate two additional techniques into my PS workflow: Shadows and Highlights for increasing colour in the RGB image and HDR toning for increasing contrast in the synthetic luminance layer. LIGHTS: 42 x 300s + 23 x 600s; DARKS:30; BIAS: 100; FLATS:40. Taken with a Trius SX-26C and SW ED80.

    M42 - The Orion Nebula, plus top left M43 - De Marian's Nebula (aka "The Running Man Nebula"). This is 30 x 30 second exposures, plus 22 x 320 second exposures in an HDR composite, taken 11th Jan 2014. Again I was battling a nearly full Moon as we seem to get nothing but rain around here when the skies are fully dark! This image was processed entirely in PixInsight. I hope to get some longer exposures to try to capture more of the surrounding dust.

    Omega Centauri (NGC 5139) is a globular cluster in the constellation of Centaurus. Located at a distance of 15,800 light-years, it is the largest globular cluster in the Milky Way at a diameter of roughly 150 light-years. It is estimated to contain approximately 10 million stars and a total mass equivalent to 4 million solar masses. This photo was imaged using a 8" SCT and a Canon 40D DSLR at 2032mm focal length. The total exposure was 97 minutes, 17x60sec, 12x 150s and 10x300sec subs at ISO800.

    GIF made of two images taken about 13 mins apart (00:30 and 00:43 on 09/03/2017). I wanted to catch the Europa transit but cloud scuttled my plans. My best image of Jupiter yet...I will next see what happens when I add my Teleview 2x Barlow to the mix! I haven;t been that impressed with the Barlow in the past but that was before I realised the the telescope needed more than 1 hour to properly cool down. Telescope: SW Skymax 150 (F/D = 12) Focal length 1800mm. Camera and optical accessories: Canon 550D in 640X480 movie crop mode, ISO 200, exposure 1/100s. A Baader fringe killer was added to reduce any CA. Processing: Initial frame decompression and quality sorting was done in Pipp. I retain the best 3000 frames from about 3 mins of data (10800 frames in total) and disable the auto-centering function (this causes conflicts with Registax). In Registax, I use around 13 align points and stack using the registergraph. I stack only frames that make it past the best 90% in the registergraph. I then increased the first 3 wavelets to around 75% and the last wavelets to around 50%. I use RGB align estimate to remove residual CA and increased gamma to 1.2.

    My first bi-colour narrowband image of the Cresent Nebula, the total integration time is 14.5hours. Ha is mapped to red, OIII is mapped to blue and synthetic narrowband green was created from a combination of Ha and OIII via Noel's actions. I also decided to show a few subs of broadband data in order to create a more realistic starfield and decided to try out creating synthetic broadband green. The Ha, OIII and synthetic green where blended using the PS technique described by Don Goldman in Lessons from the Masters. Having created an RGB image I then created a synthetic narrowband luminance image on which I performed all sharpening and contrast enhancement. The star field was processed separately and blended into the narrowband image via a star mask. LIGHTS: L:5; B:12; x 600s; Ha:5; 16 x 1800s.; DARKS: 30; FLATS: 40; BIAS: 100 all at -20C.
