    Cassiopeia and surrounds

    From the album: Widefield Images

    A section of the Milky Way centred roughly on Cassiopeia. 14x 3 minutes exposures using a modded Canon 650D, Sigma 24-105 lens at 24mm, f/4.5. The Perseus Double Cluster is visible at the bottom with a whole string of DSO's right up to the Elephants Trunk area in Cepheus.

  2. hi all, thought I'd share a wide field of mine captured on Saturday night (13 Oct) It's another Cassiopeia widefield - is it me or are there loads of us imaging this constellation recently? Shot with my Sony Alpha 200, Sigma 28-70mm F2.8 lens @ 50mm wide open, ISO 800. IIRC it's total of 65 x 20 second lights, 60x 20sec darks and 20x 1/4000sec bias all stacked with DSS and post-processed in PhotoShop CS4. Solved by Astrometry with the following details: (RA, Dec) center:(19.3779150171, 61.1835725999) degrees (RA, Dec) center (H:M:S, D:M:S):(01:17:30.700, +61:11:0.861) Orientation:158.33 deg E of N Pixel scale:44.52 arcsec/pixel Parity:Reverse ("Left-handed") Field size :25.33 x 16.30 degrees Your field contains: The star Caph (bCas) The star Schedar (aCas) The star γCas The star Ruchbah (δCas) The star Navi (εCas) The star ηCas The star ζCas The star ηPer The star κCas The star θCas NGC 129 NGC 281 NGC 869 / Double cluster NGC 884 / Double cluster NGC 896 IC 1795 IC 1805 NGC 1027 IC 1848 Here's the annotated version: and the un-annotated version for the purists: If you think there's more data to pull out, or would like to have a go, I have the raw TIFF file saved from DSS uploaded to my DropBox and can post a link if you want to have a go with it.
  3. From the album: Slynxx Learning Curve

    First try with SW Star Adventurer. 20 x 60sec subs. No Darks. Edited in Photoshop.
  4. Came across this one by accident while moving the telescope around in CdC. A rather nice cluster don't you think? RC8 f/8 14x120s 350D modded More details here. Mark
  5. From the album: Starchasing

    Beautiful area of sky!

    Cassiopeia

    From the album: Constellations

    I did this image of Cassiopeia as I wanted some files to play with to get used to DSS, i'm both pleased with the result and disappointed, pleased because I snagged an aweful lot of stars and they are round pin points instead of blobs lol disappointed because I know that the milky way runs across this patch of sky and I have seen beautiful images full of colour, I failed to get any of the milkyway to show up even after stretching, and any colours I managed to capture in the stars are very subdued, this is only my second attempt with DSS though and i'm sure there is a learning curve to navigate. I'm sure the short exposure has a lot to do with my results though and much time will be spent experimenting ;-) Camera - Canon 5D Lens - Canon 70-200L @ 100mm f5.0 Exposure - Lights 20 X 5 secs Darks 10 X 5 secs Static tripod.
  8. Here's some images I shot yesterday morning at Valley of Rocks in Lynton, North Devon. All taken just with my tripod mounted dSLR, no tracking. I did take extra long exposures for the foreground which I intended to add to the images in post but it was so dark that by the time the foreground was exposed enough in camera it was very, very noisy so I left them out. You can make out the silhouette of the rocky hilltops just about though. All images were taken at ISO800 & were a stack using DSS of 3 frames of 15secs each apart from the Ursa Minor which was 40secs exposures.

  9. Last night seemed pretty dark and clear at about 10:30, due to ... A long story, no astro gear was accessable so I rested my HTC10 on the patio table , set it on manual mode 16 seconds at ISO 1600 and captured Cassiopeia, surprised to see (of you look hard enough) the double cluster and a very feint Andromeda.
