  1. 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.
