  1. Thanks - it's useful to know there are other usability issues. I'm a longtime Canon user so I'm biased as well but the technical data is quite compelling on the lower noise and sharpness of Nikon images over Canon. iscit also the case that more of the third party software is for Canon and there is less support for Nikon?
  2. Hi - it used to be the case that astrophotographers using DSLRs generally preferred Canon technology to Nikon because of the lower noise Canon sensors. However benchmark tests with organisations like DSomark.com seem to favour many Nikon cameras over Canon and in some of the tests I've seen certainly some of the full frame Nikons appear to deliver images with a lot less noise. If we are focussed on recovering detail in the shadows in post production, much the same as "daylight" photographers, then is Nikon now leading Canon or are there other factors to take into account. Thanks in anticipation of your help.
  3. It just shows everything is a compromise; magnification, aperture, weight, cost, lens quality .... Most importantly though I guess it comes down to personal preference. All the comments here have been really useful - thanks everyone - and Gary Seronik's article gives an entirely different perspective on IS. From my perspective I know I shake and I don't expect to be investing in too many pairs of binos so I want a pair that will do the job well for me in most instances and if IS gives a significant advantage then I'd not be adverse to "investing". If I can see more with less additional equipment, tripods, neck pods etc, then that ticks my bang for buck box. Time to go and test out some binos I think. Many thanks. Markatw
  4. Many thanks Steve and Charic - that's a good point! I've just hit a birthday I'd rather forget and bet I'm not functioning at 7mm although I'll need to check. The video was really useful - in my naivety I thought the IS would deliver something more magically steady. I understood it was the high frequency buzz that the system damped but I thought it would deliver more. On that basis a mount would probably be money better spent? As I want the binos though to be able to be portable and just grab and use them, then the 7x and 8x options look like a better bet for me than 10x50 or the IS options if I've understood correctly? Thanks
  5. Charic Many thanks for the advice - I was thinking about 10x50s then saw the IS binocs which are expensive but I do seem to suffer from lots of shake so that option is attractive. However I am very much a beginner, so something smaller like a 7x50s might be just the job for learning the sky and also as they'll be lighter to handle and help reduce shake? Does that seem reasonable? Many thanks
  6. Hi - sorry for the 'beginner' question - I was just wondering how much narrower the field of view is on the 18x50s as opposed to the 15x50s. Can you still get the Pleiades in full view in the 18s for instance? Many thanks
  7. Many thanks - I'll start trying some out
  8. Hi does anyone have any experience using the Opticron HR WP Advanced Porroprism binoculars? I've heard that porroprisms can often out perform roof prisms in the same type of price range. These binocs seem to have the odd very positive general review but I wondered if anyone had any experience using them for stars gazing. Many thanks
  9. Dear all - many thanks for your replies - it was worth a try! I've seen in the threads that people recommend a fixed 300mm lens as opposed to a zoom to avoid instances where the zoom can creep on long exposures. I was keen to go for a zoom for its flexibility. Has anyone had any problems using zoom lenses?
  10. Oldpink - thanks that's very helpful. Maybe I'll just buy a cheaper lens and an astrotrac and have done? Thanks
  11. Hi - I'm looking at buying a secondhand 300mm lens for my Canon DSLR to start taking images. I've come across Canon lenses that have in built image stabilisation. I don't have a tracking mount. Does anyone know if, or by how much, the image stabilisation system can extend exposure times before stars start to create trails across the image? Many thanks.
  12. Hi -- has anyone got a decent view of the moon tonight - it's sitting behind low cloud in North Tyneside but it's a distinctly reddish blur - or is it just my eyes? Hoping you are having better luck
  13. Great view of the moon tonight in North Tyneside set against a similar very clear blue sky. Mars also looks very red tonight here set off perfectly against the blue background. I only view through binoculars but the contrast of the bright white moon against the deep blue sky makes for an excellent image. A really good night for us in contrast to the recent run of fairly cloudy and misty nights. Hope others are enjoying the view.
