All Just had an hour with the 12x50 bins following AN magazines November binocular sky feature. Basicly a hunt for M's 36, 37 and 38. Found them fairly quickly Starting from Alnath to HIP25291. Just on the edge of the fov was M36 a sharpish fuzzie. Once located both M37 and M38 could both be located on the edge of fov above and below M36, both appearing as less distinct faint fuzzies. For all 3 M's i had to use averted vision Pleased as punch with that hour and 3 more M's chalked off and my first chance to scan Auriga. I also passed many rich star fields that i havent identified due to the initial hunt for M's
It was a lovely clear night tonight (23/11/14) and while the scope and DSLR were busy imaging I had a search around with my 10 x 50s. The region bounded by Capella, Almath and theta-Aur is rich with open clusters and I spent quite a bit of time soaking in the view. There is a neat triangle of clusters defined by M36, NGC 1893, and the pair NGC 1907 and the starfish cluster. They all neatly fit in the field of view of my bins.The open clusters NGC 1857, NGC 1778 and M37 are all close by and this region is well worth a visit.
A quick RGB set of data from late Nov - taken while waiting for Orion to clear a tree! 45:40:40 all in 5 min subs, ST2000XM through FLT110 at ~f5.6, all on the Titan. Reduction and processing in PI, with final small tweak in PS. Couple of interesting objects here aside from the cluster itself (which is 4100ly away itself). OW Aur is the deep red star in the lower left (varying between mag 12.3 and 13.6) - this is another example of a carbon star. Also visible (just!) is "Holoea" - this is part of a bipolar outflow from a Young Stellar Object, and can just be seen in the image below. More details from the paper linked up from my page here: https://www.chromosphere.co.uk/2017/02/09/m36-carbon-star-ow-aur-holoea/ Thanks for looking!
Hi folks, Another reprocess of old data (from last December) to see if my skills have improved. Here's one which includes the Flaming Star nebula, rather deeper than my previous effort: Flaming Star - includes M36, M37, M38, IC 405, IC 410 and IC 417 The full sized 4096 pixel square version is available here (6 MB download) - beware, horrors may await the avid pixel peeper! The challenges for this one were to separate out the faint Ha from some residual sensor noise and to decide how many stars were enough - there were a lot more in the RGB subs. At the image scale offered by the 165mm focal length lens the reflection nebulosity was difficult to extract. I decided where it was by doing a blink comparison of the 1000 second blue stack with the full RGB image (the version with all the stars plus some nebulosity) and then it was a matter of isolating it from the bright stars that were illuminating it. It was added to the Photoshop stack of Ha (no stars) plus RGB (just stars) and the final challenge was deciding how strongly to show it - the reflection nebulosity should certainly be weaker but then it risks geting lost in the artificially strong Ha signal. Something that I didn't find in the original processing of the data last year is the "sugar cage" just creeping in at the bottom of the image at about six-thirty. Has anyone got a shot of the full object? Bob. Shooting Information: 8 x 1000 seconds exposures of Ha 5 x 200 seconds through each of Red, Green and Blue 3 x 1000 seconds through the Blue filter for reflection nebulosity Camera: FLI ML16803 cooled to -25°C. Lens: 165mm focal length f/2.8 Pentax medium format Pointing at: 5h 25m, +34° 30'
