    With what seems like weeks of cloudy nights even when it's supposed to be clear, I decided to reprocess my photo of M45 the Pleiades star cluster.

    Thank you Seanelly.
  5. +1 for Stellarium mobile. I find it extremely useful indeed!
  6. Though I haven't used the exact lens you're thinking of buying, I have used a Sigma 120-400 mm F4.5-5.6 zoom lens with a Canon 60D APS-C camera and gotten some pretty useful results. See below for an example image.

    The Sun 2.jpg

    The black dot is almost certainly debris in your image train. A careful but deep clean is the only way to get rid of it. It runs in my mind that on the day you took your image, the solar disk was devoid of any sunspots.

    I use a Seymour type 2 glass filter that I purchased from Rother Valley Optics. https://www.rothervalleyoptics.co.uk/seymour-solar-sf525-525-type-2-glass-solar-filter.html

    The Sun 2.jpg

    The Sun taken through my solar filter this morning 22/6/18 at 11.30am. After a couple of weeks with no sunspots visible due to the solar minimum, it's nice to see a couple of sunspot groups. The central group is designated as 2115 and the group upper right is designated as 2013. This is a stack of 28 images stacked in Sequator and processed in Photoshop.
  11. I have the EQ3 Pro Synscan mount on the lightweight tripod. With my ES ED80 and my Canon 60D, I haven't noticed any issues thus far. Obviously, the HEQ5 will be more stable and able to take a significantly greater weight. However, portability was of primary concern to me and that's why I went with the EQ3 pro.
  12. My EQ3 submission is the Elephant's Trunk nebula. Shot using my ES ED80 triplet APO and my Canon 60D 69x90sec light frames 29x dark frames 25x flat frames 50x bias frames Stacked in DSS and processed in PS.
  13. The Elephant's Trunk nebula(IC1396). 69x90sec light frames unguided 29x dark frames 25x flat frames 50x bias frames Stacked in DSS and processed in PS. I honestly think that up to now, this is probably the best deep sky image I've ever shot. Needless to say, I'm rather pleased with it. Any constructive tips or criticism will be more than welcome.
