  1. From the album: First Images

    © AMG Walles

  2. One of the largest and brightest globular clusters, M3 is about 33,900 light-years away from Earth and contains around 500,000 stars. 26 x 30 second exposures at 6400 ISO plus 10 dark frames and eight flat frames. Processed in Deep Sky Stacker and Photoshop CS6.
  3. The bright, almost fully illuminated moon doesn't interfere as drastically with bright objects like globular clusters as with fainter, less condensed targets. This is an RGB image of M3 - I never bother to make L exposures with globulars these days, the signal is generally strong enough in the colour channels not to need it. Minimal processing - just stretching and a little sharpening in PI. 12" TS/GSO RC at F/8 on a Mesu 200. Atik 383l+, AtikEFW2, ATIK OAG, Lodestar X2, Baader 36mm filters R=G=B = 5 x600s binned 2x2. Click on the image and then select "Full Size" if you want more detail :-) Comments welcome Derrick

    M3, 7 x 1m

    From the album: 20170402 EAA

  5. Hi, Came back home late this evening and noticed that the sky was clear - kind of, some high clouds from time to time. Waited for a while and it seemed that it could stay clear. I had some issues last time I tried my 130PDS, tilt/misscolimated/idk so I thought to try the 90/900 binned 2x2 unguided, short subs as it needed no adjustments. Put the scope, put the camera, focused and set up a plan of 6s. I was aiming for 30 minutes. Drank some beers and some so I thought that 6 is easier to divide with, rather than 5. Nevertheless, I didn't finish the plan of 300 subs, some clouds rolled in. I got scared of them and I decided to park the scope and take flats and darks and I was too lazy to resume captures again for M13, even though it seemed clear again. But I'll have more time next months. And I also didn't have the RGB filters in the FW, I had only LSHO. Enough writing, here's the result (~160 subs of 6s, L filter, 300gain, -15C, bin 2x2 @900mm, F/10):

    From the album: Deep Sky Objects

    M3 - Globular Cluster My first attempt at a globular cluster. I had a feeling that this would be a tricky target and I was right. But not bad for a first go. Globular clusters, often referred to as Jewels in the Sky and it's easy to see why. These amazing clusters of stars are orbiting our galaxy and so are actually part of it. This one was discovered in 1764 and is estimated to contain 500,000 stars and around 8 billion years old. It is approximately 33,900 light-years away from Earth.

    M3

    From the album: Photos from Bury

    M3. Processed using DSS. Hardware details: Camera: Nikon D200. Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 57 x 3min at ISO 800 taken over 4 days of imaging, Darks: 20 x 3min at ISO 800, Lights and darks separated by 1 min intervals. Flats: 40 x 1/40s at ISO 800, Bias: 30 x 1/8000 at ISO 100 Dates of capture 17/03/2016. Conditions: Clear sky. Seeing was good, moon was strong. The guiding was stable and unguided, I could get 1 min subs. . The wind was very light. I increased the saturation by 25% and aligned the colour channel histograms until the dark signal at the edge of the image was the same as in the original photos.

  14. Hello! First time posting here - it's been a while since I have imaged (are the Astronomy Forum servers down indefinitely?). Anyway, tonight was the first time in a year and a half that I imaged anything. Here we are, M3 with 90s subs on a C8 and a Canon Rebel XS/1000D (no focal reducer)!
  15. M3 From the other night, naff conditions, so I was surprised it came out this way. Very short exposures, but being so bright I could get away with it. Equipment used was a skywatcher MN190, an Atik 314L plus mono. Plenty of exposures though at 40 x 10 seconds.
  16. A quick shot of the M3 globular cluster taken on 10th January. 18 x 15 second exposures at 6400 ISO. Processed in DSS with x3 Drizzle. Final tweaking was done in Photoshop.
