  1. Hi, I have taken mono LRGB images of M51 with my new ASI1600mm-PRO. I have a mix of 30s, 60s, 120s subs. 100 darks, and 100 flats for each filter. About 4 hours total. I Used DSS for alignment and stacking, then Pixinsight for LRGB combination. My issue is that i'm not happy with the colours, the stars all appear white and the background is strange. I have attached the Aligned LRGB images. Can anyone point me in the right direction? Thanks! Green.TIF red.TIF Lum.TIF B.TIF

  4. After having a crack at the moon I thought why not give it a go, so took about 30 subs and 5 darks, ISO 1250, 2 min subs. Put it through DSS and had 11 frames for 20 mins. Wernt even sure if anything would come out as I couldnt see anything on liveview. Well I wernt expecting that for a first attempt, I did tweak it in lightroom and prob went to far with it but got to say I am chuffed to bits with it
  5. Evening folks, This is my first attempt at M51 and probably my best at post processing, having some trouble getting rid of the blueish hue from the Astronomik cls clip filter but got rid most of it. this was taken with the following: SW 200p and eq5 pro Finder Guider QHY5v Canon 550D unmodded 15 x 300s lums 9 x 300s darks 9 x 300s Flats Any advice in processing would be greatly appreciated Thanks http://www.flickr.co...tream/lightbox/

    From the album: My quest for DSOs

    First go at the Whirlpool. There was some thin upper cloud.
  7. my first DSO pic in aaaages, since October last year in fact, large doses of real life have been getting in the way. A very common target, but my best take of it by a long way: 18x 420s lights at ISO1600, bias darks and flats, 1.5x barlow, equipment as per sig, developed in Pixinsight. And just for a laugh, here is my previous effort:
  8. Messier 51 - The Whirlpool Galaxy by Chris Kennedy, on Flickr Happy to get this one in, as it's now snowing here in Mansfield, England! Friday night/Saturday morning was the first clear night I've seen in over a month, and thankfully the 11mph wind was coming in from the North, so the gear was sheltered. My garden is less garden and more swamp currently, indeed expecting Yoda to come out of a hole and point out the first temple of the Jedi. So I pre-sank the tripod a few inches in to the ground and then leveled it - was a pain to pull it from the frosty hard ground the next morning! I originally got my ATIK414ex for narrow band imaging, as light pollution in suburban Mansfield is awful and rather limiting, but I can't resist some of the more iconic galaxies! Even if processing can be tricky! As there's a Moon rising - will probably spend my next session going over M51 in H-alpha, really to bring out the star forming regions, perhaps also a few really long exposures to add background stars. Imaging Details: RGB Sets: R x 30 | G x 30 | B x 30 - 6 hours initially, but re-shot 15 of the R set as M51 was higher in the sky, so sky background levels where better. Optics: Meade LX90 8" SCT, f6.3 Focal Reducer, Baader RGB filters. Camera: ATIK 414ex, -17c, bin 2x2, 240s Guiding: ASI120mm, ATIK OAG, error 0.7 - 0.9", PHD (Also used for drift align) Datasets: R 30x, G 30x, B 30x, Per channel flats Processing: DSS, Photoshop Conditions: Ground saturated, pre-sunk tripod, 1c/-1c, Wind 11mph (sheltered), occasional cloud cover (10%), Suburban light pollution.
  9. Hi all, Novice here, 2nd attempt at imaging DSO. Aimed to capture M51 last night but think I might have been off target. I thought my polar and synscan alignment was pretty good and synscan seemed to be on target for other objects. Can anyone tell me if I was off target or just didn't get enough data? I have tried matching the surrounding stars to other images of the area but can't seem to figure it out. I have attached the .tif output from DSS. I have played with levels and curves but can't reveal anything yet. If it's bad news, can anyone at least identify the faint fuzzy for me? Thanks in advance Details: Skywatcher 200PDS + HEQ5Pro mount Lights 60x60sec ISO 800 10 darks, 10 bias Autosave.tif
  10. I'm reasonably pleased with this but there's lots to improve. Needs to be less noisy for one. Unguided Canon 50D, 20x43s subs 5xdarks, ISO800, used DSS and Photoshop CS3. Thanks to @carastro for her guide - it was very useful indeed.
  11. Hi everyone, This is the 2nd ever DSO I have captured (the first being Pleaides). I have very limited experience processing images after stacking. I have attached some of my efforts to draw detail out of M51. There is only around 30mins of data in the TIF file (30x60sec @ ISO800, Skywatcher 200DPS), 10 darks and 10 bias. This is all I could capture before the clouds rolled in. I have tried following some youtube tutorials but am struggling to get rid of the grey-ish tinge to the image and reduce the noise. There also seems to be a dark horizontal band across the image which I think might be a stacking artifact ? I am using Photoshop and have mainly been adjusting levels and curves but not quite sure where to go next. If anyone could give some advice on processing M51, what processing steps they normally take etc.....or even have a quick go at processing it that would be amazing. Thanks in advance Autosave001.tif
  12. Hi everyone, I'm slowly adapting my knowledge of Astronomy and Astrophysics and have purchased a 'Sky-watcher Explorer Diameter=130mm Focal Length=900mm' (see image) . I would just like to know what kind of eyepiece to buy to get a good view of Mars because my current view with a 'Super 25mm' eyepiece is very disappointing . Thanks, ajc0502
