  1. The latest edition of the Binocular Sky Newsletter is ready. As well as the usual overview of DSOs, variable and double stars, this month we have: Several lunar occultations, including one of AldebaranComet Catalina now visible in the morning skyMeteors from Asteroid 3200 PhaethonA mini-review of Vixen's SG 2.1x42 binocularI hope you find it useful. To get your (free!) copy, go to http://binocularsky.com and click on the newsletter tab.
  2. You can exploit the changing perspective of the view of a comet from Earth to construct a 3D image. This is my effort using 2 images of the comet taken 24 hours apart - the comet moved over 2 degrees against the background sky allowing the ion tail/dust tail angle to decrease by ~ 5 degrees. Its this change that provides the information your brain needs to see the ion tail stretch away into the distance If you can stereo "free view" with relaxed eyes - use this image - - click this image If you can stereo "free view" with crossed eyes - use this image - - click this image If you have an optical stereo viewer that can be used to view a computer/notebook screen then use the relaxed eyes image pair. Something like an OWL viewer works. The technical cards of both images give details of the comet registration method used to create the 3D effect. Thanks for looking
  3. This is my first light image using my new observatory dome installed last October - thanks to the weather! So the image was taking on the morning of 15th January exactly 3 months after installation. - click image Thanks for looking

    Comet Catalina

    From the album: The next step.

    Was really chuffed to catch this comet, especially with the two tails. This i believe is the 5th comet i've caught 'on film' as it were. Along with Panstarrs - ISON - Jacques, and Lovejoy (forgot the numerical names). Equipment: ED80 - / 350D -/ EQ6 -/ CLS clip
  5. What a thing to wake up to. I had no idea it just showed up in this morning's mail. Thank you so very much ASTRONOMY magazine and everyone on this fine site for all the help and advice over the years that helped me obtain this image of Catalina. Look up!
  6. While I wait to capture some star field shots to merge all my comet data with here's a single 300 second frame of the convergence at 5.a.m. here over the coast. Hope you had a chance to at least view it. Amazing thing looking through my 800mm Newt. Look up!

  8. From the album: David Newbury

    I took some images of Catalina last year. I was working on PixInsight and came across BLINK. That put me on the road to creating .GIF movies images. Taken using ATIK 4120EX on my C11 using NEQ6 mount from my garden in UK.

  11. Some images of Catalina as it progressed from northern Virgo to mid Bootes. All imaged from outside my caravan 21st December 2015 - 1st January 2016 - 8th January 2016 -
  12. Another attempt at Catalina from early Friday morning. This time I used star adventurer with canon 70d and my tamron 150-600 at about 250mm. Must say this lens is so difficult to focus and I'm not sure of its quality for this type of work. I'm not sure if I should invest in a canon 300 f4 prime as thats a cracking lens for my wildlife photography as well or go for a small scope such as an altair astro 70 purely for astro imaging. Then I'm not sure if the star adventurer would cope with the weight? Decisions decisions!! I also had problems with DSS with this one as well. I'm not sure if I've mucked up the comet settings as it kept getting right to the end and less than one second to producing the final image before locking up! I did get something out in the end but again not sure how many it stacked, I think about 14, 35 second exposures. As always my photoshop skills are suspect!!!
  13. Spent the morning from 3:30 till almost 7 a.m. and managed to image 12 keepers after it cleared some trees. Not as large a comet in my 560mm SV80ED as Lovejoy from the beginning of the year but still a thrill to capture.The moon washed it out some. I wish they would come around like this more often. Like this comet the year really flew by. Gonna give it a go again in the morning. I really needed more frames but a pesky tree is blocking the view for half and hour. I should also have added some bias frames to this but was in a hurry so it is what it is. Let me know what you think and Best of New Years to everyone! 12-300 second lights @ ISO 800 15 darks. One set stacked on just the comet head and one set on the stars using sigma kappa method. The 2 tiffs where then blended in PS and tweeked in LR.
