  1. From the album: Deep Sky III

    I was interested to see if I could get more detail from my M31 4 panel mosaic acquired with my SW ED80 by applying new lum data acquired from my Esprit 150. With the same camera, the FoV of the Esprit is only about 1/4 that of the ED80, so I decided just to enhance only the core with the higher resolution data. I used RegiStar to overlay the existing mosaic with the Esprit 150 lum data and then blended the two images together using PS and PI. The details of the subs are below: ED 80 1 2 3 4 L 16 16 18 12 600 s R 19 12 15 13 600 s G 16 18 9 10 600 s B 18 19 13 16 600 s H 5 8 6 6 1800 s Esprit 150 (M31 core) L 27 300 s

    M31 (Mosaic)

    From the album: Deep Sky II

    My first attempt at a mosaic image. I choose M31 since it required only 4 panels to achieve a reasonable framing. After calibration and stacking in CCDstack, I decided to combine the mosaic panels using a combination of RegiStar and PS. After a little experimentation I was able to achieve an invisible join between the panels. This was also my first application of Pixinsight's DBE, Background Neutralization and Colour Calibration functions on an image. I was particularly impressed by the DBE function which gives superior results than the PS equivalent. The image is a H alpha red blend LRGB image and for those that might be interested, consists of the following sub frames for each of the four panels: 1 2 3 4 L 16 16 18 12 R 19 12 15 13 G 16 18 9 10 B 18 19 13 16 H 5 8 6 6 The LRGB subs are 600s and the H 1800s. The H was blended with the red channel using the PS screen function after black clipping the H image. I think this might be my last mosaic for a little while since it took about 5 weeks from start to finish, mainly due to the UK weather and the fact that I wanted quite a long exposure per panel (c 13 hours) in order to capture faint detail. I took it as a good sign that you can see the faint dust clouds in the companion galaxy (M110) reasonably clearly.
  7. From the album: Photos from Bury

    Andromeda galaxy group (M31, M32, M110). Taken with a SW Evostar 120 mounted on an auto guided EQ5. The image is stacked from 10 lights and corrected using 2 darks, 20 bias and 1 flat image. The calibration is not correct, probably because of the unequal numbers of darks, bias and flats.

  10. From the album: Canon EOS 1100D Images

    M31, reprocessed, 5 and 10m exposures 18 frames (don't know the integration time anymore, neither the no. of flats and bias I messed around with this so much). I decided to keep it real on this one (I'm won't to overprocessing in my light-polluted area, so I don't even lose one filament of detail). After changing the file name on the subs,(RAW to Tif), resizing and cropping, I made a gradient removing flat for each of them, and processed them normally after flat application / subtraction. I forewent chasing details in favor of nice values, such as RGB 23/23/23, or as near as I could come to when processing, to find a blend between detail and a pleasing view.

  14. After a first attempt at M31 a couple of weeks ago, Mrs WaveSoarer and I had another go this evening with her SLR at prime focus. I managed to focus the camera really poorly at our first go this evening and the stars were all polo mint shaped. We then followed advice from our attempt on the ring nebula and we took a long exposure and then checked the focusing on the screen on the back of the camera body. All seemed well and I even remembered to lock the focus to avoid it slipping. We reduced the ISO this time from 1600 to 800 to help reduce the noise and Mrs WaveSoarer stacked 25 of the 30s exposures in photoshop. The scope was tracking with a reasonably good polar alignment. We're quite happy with the result and I rotated the camera to align the galaxy with the diagonal of the frame. We just missed M32, though, which you can just see as the glow at the bottom right of the frame. There are no dark images used and we'll have a go at that some day soon. You can see a purple artifact at top left which comes from the sensor, this appears on all the images we've taken so far, and we'll need to use darks to correct this out. We could have used far fewer subs to produce a similar result but we used all the data we had.

  16. Messier 31 Andromeda Galaxy Distance from Earth - approx 2.5 million light years After spending ages getting a decent polar alignment, the clouds were on their way in so I only had a small window of opportunity remaining. This was my first real run with the new setup (minus the ST80 and ZWO ASI120 as i was having issues there) and I almost gave up. SO glad I didn't!!

  18. The Andromeda Galaxy (M31). This shot was taken over a couple of nights (28th July and 1st August 2017). It's a shot I've been wanting to try for ages but M31 appears so large that I had to wait until I had a scope with a shorter focal length in order to capture this much of it (and it still doesn't fit in the frame). Previous attempts were made with a 400mm lens on a DSLR which although quite reasonable didn't really capture the true majesty of this object. 81 x 75 second exposures at 400 ISO (approximately one hour and 41 minutes integration time). 60 x dark frames 100 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity and Photoshop Equipment: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  19. Part of Andromeda Galaxy (M31) with companion galaxy M110. This is a bit of an experiment really. The Andromeda Galaxy is too big and too close to us to be able to fit it all in one frame with my 1500mm focal length scope (it appears about the size of six full moons side by side to us), and using a normal lens to capture it inevitably means a loss of detail. So the aim here is to capture some of the galaxy with its core and outer edges along its most noticeable satellite galaxy. So far its had just 48 minutes of exposure time and from a darker location than usual (Kelvedon Common in Essex). The results are encouraging - some more exposure and it could look quite nice, and maybe inspire me to put together a mosaic at some point so all of the galaxy is shown. Unfortunately we ran out of battery power before getting sufficient frames to finish this shot so it's one to return to later - hopefully on a clear night with no full moon. 6 x 8 minute exposures at 400 ISO (48 minutes) 27 x dark frames 20 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with digiCamControl Guided with PHD2 Processed in Nebulosity, Maxim DL and Photoshop Equipment: Celestron NexStar 127 SLT Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  20. First completed image in over a year and a half. I've started a couple of other projects but with work and the UK weather I've not been able to complete them. Anyway 90mins in Luminance and 30mins each in RGB taken with my AG12 and H35 starlight xpress. Conditions were windy while capturing the RGB frames so not a perfect set of colour subs. Any comments welcome Worth taking a look at the full res....don't look too closely though as I have a very slight tilt on the camera Thanks for looking BTW just going off topic anyone off to the IAS next week?
  21. his is a quick 1hr 30 mins or 18 x 300 secs at ISO 800 with the cooled DSLR. I have reprocessed this so many times i have actually lost count, my eyes hurt from staring at the screen and as such i turn it over to you guys. It was windy too, seeing wasn't great and there was some high level clouds plus, as always, RH was very high. Kit used HEQ5 Pro, SWED80 0.8 FF/FR, Canon 550D full spec and cooled, IDAS MFA D1 Filter. I tried not to use too much NR and as Paddy recommended better star control, i paid attention and tried to control them better. I may have overdone the star colours though. I wish i could have had more time on target, but we get what we can take. It's not pretty but i am happy given the limited time.
  22. Good evening all. Well the SA arrived this morning and following an early evening of what looked to be perpetual cloud, I stepped outside at 9:30 to find clear skies. I pratted about rolling around on the floor for 20 minutes trying to get PA before finally starting shooting. I used the optional counterweight etc so that I could still see through the polar scope. Nikon D810 with Nikkor 70-200F4, at F4 with 2 minute exposures @ ISO800. Also took 10 darks and 20 bias. out of 11 lights, 7 frames were of reasonable quality, I used DSS to stack the best 5 of these and then did some (admittedly poor) post processing in PS CC and Lightroom. Considering ive only spent 20 mins or so stretching this (and in all honesty I can do no better), and then using a mask to underexpose some of the surrounding area to rid the noise from the LP, I am made up with the result. In order to make the stacking quick I also cropped heavily before any stacking (1900 x 1200 pixels approx). Would love to post the data somewhere to see if anyone of you wizards can pull any more from it, any takers? Comments always welcome :-)

  24. Hello world, When I first got into Astronomy in August last year, one of the very first DSO that I looked at was M31. I was a bit disappointed in what I saw at the eyepiece, especially when I compared it to the images that I had of the galaxy. I decided to take the family on a holiday to a dark sight in Brittany on a holiday, to see if I could get some pictures. When I plugged my old 350d onto the back of my 127 Mak at the time and took some exposures, I was expecting to stack them and see something amazing. What I saw was not that much better than what I had seen from the eyepiece. At this point I almost packed in the whole gig and put all my kit on ebay. I sold my camera, and my alt az mount, so all that I had left was the Mak (which I later used to some good effect on planetary) Anyway, over the last year, I have given a renewed vigour into Astro and purchased a EQ5 mount and a 80ED. So when M31 cleared the trees last weekend, I thought that it was time to take on my Nemesis. Not wanting to take any chances, I did exposures at multiple lengths, from 30sec, 60sec, 120s, 180s and 300s. This way I had a variety of exposures to play with to control noise versus the luminosity. The final recipe has been to use the 180s and 300s exposures for the lum and the 60 sec for the stars and the core. This has been a bit of a processing marathon as the combinations available are numerous. I have downloaded some new processing actions and been doing research on the net. This is what I have achieved to date on the processing, with some real noise issues (summer temps still high for the UK.) I have seen better, but this is pretty special to me as it has been a massive learning curve over the last year. Let me know your thoughts, experiences and advice, tips tricks etc. Or post your images of the subject, especially if you have been through the pain of using a DSLR. Thanks for looking, dark skies ahead!
