  1. As the title really. I don't count myself as a serious imager. In fact i'm a beginner. I have a 6D and 3 lenses. As well as my terrestrial stuff, i enjoy a bit of prime focus from time to time, mainly Lunar, occasional white light Solar, and a bit of wide field if i'm at a dark site. Before i got the Canon, i was a Sony A7 mirrorless user. The one thing i miss with the Sony is its focus peak feature when imaging the Sun or Moon through my scope. It made focusing a piece of cake and gave me some nice (if basic) images. But no one seems to like the Sonys sensor for astrophotography, and most images prefer the Canon sensor. Anyway, i'm in the market for a smaller sensor to use with a scope i have that won't illuminate a FF sensor. Rather than getting another DSLR i was thinking of purchasing a Canon mirrorless. Something like a M6. I just wondered how the APS sensor in that camera stacks up against those in the DSLR range ? Is anyone using them for imaging ? And can you modify them for astrophotography ? Thanks all.
  2. My binoviewers max out at 185x I know if the seeing supports that sort of power, i'm doing very well. With Mars, Jupiter and Saturn being poorly placed 125x is more the norm. Lunar for me, much the same. Solar i'm using around 40 to 50x which i find is plenty. With the Dob, mostly i'm working at 50 - 100x For me Low power, wide angle and rich field is best, with a binoviewer if i can.
  3. Lens Clear Out (Canon fit)

    I can recommend the 135F2 Reputed to be one of the sharpest primes Canon have ever made. Its certainly impressive to me.
  4. Comically bad session 14/11/17

    I went out on Monday morning with the intention of capturing the Venus / Jupiter conjunction ; just a simple prime focus image with the DSLR. As they were less than a third of a degree apart, they would sit nicely in my refractor. I went out early at 06:45, but had forgotten the clocks had gone back a couple of weeks ago : it was no longer dark and morning twilight was rapidly advancing. So i quickly set the mount up, and went into my shed to get my refractor. Uh-oh...its not there. Doh, i realised i'd left it in my garage overnight after making a few adjustments. In my 20 deg heated garage....!! The view of the 2 planets looked like 2 'Wifi' signals you get on your phone standing side by side !! Thermal equilibrium....no chance. I put the scope away and settled for a 135mm lens instead. But i saw the conjuncion anyway, it was a beautiful, clear morning, and Venus and Jupiter looked a treat.
  5. Eye Pieces you would like to try out

    Docter UWA 12.5 mm They have a bit of a cult following and i'd love to try a pair for bino-viewing. Same for the RKE 28s.
  6. Your best ever view through your bins

    M45 Pleiades through my Canon 15x50 from a dark site. Stunning, and i think this is one object that looks better through bins than it does through a scope.
  7. If its still available, i'll take it off your hands. Will PM you.
  8. Whats your dream telescope

    Not seen any scopes in this thread that will perform like my own...... On a night of decent seeing (half decent actually) i can easily detect subtle surface details on Saturns moon Mimas ; the Herschel crater being an obvious feature. Must be the 1/200th wave 60mm Flourite optics and 1.0 Strehl thingy....
  9. Nice capture Stuart Hypothermia ? In July............?
  10. Televue Powermate Choice

    I can recommend the Televue 2" x2 Powermate. Rock solid, and it sets a benchmark in performance. It has a 2" to 1.25" eyepiece adapter too.
  11. My mount lives tucked away in a corner of my garage. Its always attached to its tripod, so i narrow the legs in a little so it takes up a smaller footprint. There are no counterweights or any other add ons apart from the tripod tray. Although a bit unwieldy i can carry the whole thing carefully outside. I've found a gym membership a useful addition to this hobby. When i visit a dark site, i always separate the mount from the tripod for ease of travel. I don't want any accidents !!
  12. Equatorial platform

    That looks like Tom Osypowski's handywork !! A work of art indeed. Beautifully engineered. Good luck, and please share your thoughts after you've run it in.
  13. Curved spider vane

    Interested myself too with how this performs. Looks an innovative design. I have been thinking of modifying my own scope and purchasing my own curved vane. Theres a US company that supply them..... http://www.1800destiny.com
  14. ISS from 03.04.2017

    Hats off to you Pete. Got to be a picture of the month contender. Worth sending it in to Astronomy Now / BBC Sky at Night.
  15. I'm going to miss Jupiter

    The 13mm Naglers are i bet, similar to the 11s. The eye relief is a little tight, but its certainly no deal breaker.
