2020 hasn’t been a great year for anyone, but we’ve had a good comet, and some clear nights. I haven’t been the most productive, or even a very good imager this year, but I’m quite pleased with what I’ve learnt, narrowband has been a revelation . So I thought I would share a few of my images, and a video I put together or them. Thanks for all the great images and tips that have been posted. Wishing you all a happy Christmas and a great 2021.

From the album: Deep Sky III
I decided to try to maximize detail by collecting a large quantity of Luminescence data and then applying strong deconvolution to the areas of high signal to noise. I also decided to try out Mure denoise, a Pixinsight routine that reduces camera noise. The final result is an LRGB and represents just over 17 hours integration time. I hadn't noticed before the rather strangely shaped fuzzies in the backgroud - have a look at the annotated version for IC4278 and the triangular shaped galaxy PC2292105. -

M51 (the Whirlpool Galaxy). I spent a good portion of the night on this one. Hardware details: Camera: Nikon D200 Telescope: SW Evostar 120 with Baader contrast booster. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 35 x 3min at ISO 800 Lights (and darks) were taken with 1 minute intervals (to let the camera cool down) Darks: 30 x 3min at ISO 800 Flats: 30 x 1/40s at ISO 800 Bias: 30 x 1/8000 at ISO 100 Date of capture 14/01/2016 Conditions: Very clear sky with no cloud. Seeing was good, the guiding was not as stable, the wind w© DH Elijah

From the album: Marci’s Astropix
2hrs with EOS650D at 18Mp shooting visual colour range (240s subs @ ISO800), 1.5hrs with EOS1000D Full-spectrum-modified (no narrowband filters) at 10Mp (120s subs @ ISO800 as core blows out VERY easily in full spectrum). 5x dark frames and 20x bias frames for the EOS1000D session. No flats. Stacked in DSS 64bit with 2x drizzle, processed in Photoshop CC 2018 (very little needed doing to it to be honest, just pull the saturation up a bit to bring the colour out). This is a heavy crop hence the apparent low resolution of the final image. This was the last outing for the EOS650D© M Coyles

M51 The Whirlpool Galaxy 21.04.18 My first proper attempt at RGB imaging with the monochrome CCD Imaged using William Optics FLT-110 and Atik 314L monochrome camera. 10 x 300 seconds R, 10 x 300 seconds G, 2 x 300 seconds B (as I had to delete the other 8 due to technical issues). 10 x 300 seconds Luminence. I will have another look at this data once I have done more reading up on combining my Luminence data with the RGB data as it was a case of having a play around this morning. However, I'm very happy with my© vicky050373

M51 over several nights over February and March 2017.

I took this image over several nights in February and March 2017 using SGPro control software and ATIK 4120EX OSC on a Celestron C11 with 6.3 focal reducer and a NEQ6 Pro mount in my garden. 30 x 300s Lights 30 Darks, Flats and Bias. Processed using PixInsight. Cropped. -

A reprocess of the data captured in Feb/March 2016 (my original attempt is also in this album). This is an LRGB image with about 6 hours integration time. The main difference between this and the earlier image is that I concentrated on correcting the starfield colours and sharpening the galaxy. -

From the album: Deep Sky II
My second image with my new camera (Trius 814) and my first attempt at M51. Since the galaxy is relatively small in the field of view and stars can get relatively large when stretched, I decided to process the star layer separately from the galaxy. The Luminescence layer was sharped by a combination of deconvolution (CCDstack) and smart sharpen/HDR toning (PS). LIGHTS: L:11; R:10:G:9:B:8 at 600s + Ha: 3 x 1200s. BIAS:100; DARKS: 30; FLATS: 40. -
From the album: Deep Sky III
In 2017 I went through a major upgrade of my imaging equipment and moved from a SW NEQ6/SW ED 80 to a SW Esprit 150/10micron GM1000HPS combination. In the course of testing my new mount in unguided mode I took some M51 Lum test shots at 600 and 1800s with the Esprit 150. Rather than waste this data I decided to see if I could use it to try to improve an Ha + LRGB image that I had acquired in 2016 with my NEQ6/ED 80 combination. Since I've never tried to blend data from two difference telescopes, I decided to take the lower resolution post processed Ha + LRGB image and to treat it as "RGB" -

M51 - Taken as a quick test of polar alignment and only an hours worth of data with a full moon, so I did not expect much. However it came out better than I thought. I will have another go at this one when conditions are more favourable and aim for 2.5 - 3 Hours worth of data. If you want more detail the astrobin link is: http://www.astrobin.com/250229/ -

First attempt at any DSO other than the brighter stuff like M42 or Andromeda. Learning to use the AZ-Gti /Sharpcap polar align / windows synscan app / APT platesolving ... And guiding ! all in one night ? all went well so had a quick 30 mins on M51 (first time I'd ever managed to actually frame it ... Plate solving is amazing) 90 second subs gain 420 and 5 darks and synthetic flat for dust bunnies / gradients Wish I'd have gone longer now as tried a 5 minute sub once guiding was working which looked good . Very noisy but only 30 mins .

Hi All, once again it's been a great pleasure to share this passion with SGL friends so I'd like to say a small thanks to everyone by posting a link to some data we shot here this year. It's all yours to have a play with - just try not to show me up! It's from the TEC140 Triplet Apo/Mesu 200/Atik 460 mono rig working at about 0.9 arcseconds per pixel, cropped to reduce file sizes and aligned to fit together in Registar. You'll find LRGB and Ha in the link, though the Ha is a bit of a token gesture at 2X40 minutes. However, I found I could use it to give a hint of the star forming regions

This time, I decided to try to maximize detail by collecting a large quantity of Luminescence data and then applying strong deconvolution to the areas of high signal to noise.

This is my first ever M51. 50s subs 20Lx15Dx10B (still not flats). Taken with a Nikon D7200 at ISO 1600 on a SWED80+0.8FR. Processed with PI and a little PS. I quite pleased with the results and wanted to share although I know it can be better :-) Thanks for watching!

Freinds, I have run out of data to reprocess and no clear sky in sight until Thursday (hopefully), so I started to dig into the Liverpool Telescope archive again to see what data they have gathered since last summer (when Wim and I vacuum cleaned their treasure chest of unprocessed data). This is a remotely controlled 2 metre RC scope on La Palma (Canary Islands). So, here are two finds. A well known one (M51) and an rarely image smaller one (NGC 5248). M51: here I found the following decent subs to process: 55 x Bessell B (blue), 29 x Bessell V (green), 59 x sdss-r (red), and 3

Here is another M51, not in high res close up or majestic wide field, but something in the middle as imaged with an AA 102mm APO, G2-8300 and Mesu 200. 90 mins integration made up of 6 x 300 s L, and 4 x 300 s each of RGB. Calibrated and stacked in APP, processed in Star Tools and PS. So, it has my signature noise due to too little data and pushed too hard I think on colour saturation, but I was trying to achieve the characteristic blue stars in the spiral arms as usually seen on this subject. Will try to get some more data tomorrow night, if the forecast holds out and the moon is not

A rare clear evening so had to have another go with my Fujifilm XT-1, swapped thing around, accompanied by the usual "why doesn't this work now?" so only had time for one target. M51 was well placed, so this is the result of 17x5mins iso 1600 Meade 127 scope with reducer (should have taken that off) no calibration frames I'm quite pleased with he image for a quick session. It does mean I can get a colour image in a short time even though the ccd would be better.

This is my first image with a Canon 500D, modified for astro. Seems to be a big improvement on my unmodded NikonD5300. I guess its not the best subject for increased sensitivity though. I think some of the tidal structures are showing? And this shows what else is present....
