  1. I've been trying to spot Lulin with 10x50 binos, handheld - with no joy. Does anyone know if it is visible thru binos at the moment at what is its magnitude?? Thanks Mand
  2. Yep. that's awesome alright. last time I saw a photo like that it was from then Hubble. Get some sleep and then let us see what you can do! Well done mand
  3. Thanks for that Kaptain. just wanted to check that the orangy cast is from street lights rather than my camera being faulty. I'm going to have another go out in the countryside to see what I can get there. Thanks again Mand
  4. Tonight I had a first attempt at star trails, with a D50 and various shutter open times - longest was 30 mins. Managed to get some short trails but the whole image was bathed in orange. Would this be caused by the near by street lights, and if so is there anything I can do to avoid it - apart from moving to a better dark sky location? Much harder than I was expecting - any ideas on what F number to use and exposure times? Makes me more in awe of the images you guys can get. Thanks Mand

    Perseids

    Think so -last week saw one that left a trial. Last night saw 3 very fast and brief bright flashes - Persieds or not? Unfortunately it's cloudy here in the North Mand
  6. ......ok,get the message, stick to easier targets for now! Ta,Mand
  7. Does anyone know if Pluto is visible through binos? From my garden I can see Jupiter by 12.30am to 1am, so may be able to try to find Pluto, but don't know what i'm looking for exactly.The bright nights don't helpof course. Does it look any particular colour or show its phase, etc? Mand
  8. Yep, congrats and well done Annette. Good to hear both are doing well. Mand 8)
  9. Well it was reasonably clear for the second night running, so I had a go at part of the monthly targets. Set the OMC140 out at 10.30, then started observing at 11.30pm. Gentle wind in the garden, usual street lights but I was in the corner so conifers became my screen. Overhead was clear but even at 1.30am it wasn't very dark. Found M13 and M92 easier than expected for my first attempt with 32mm meade sr4000 plossl-62x. M13 showed up initially as a blob, but then a few individual stars became visible with a hint of blueness. More magnification didn't show much more. M92 was only seen as a fuzz
  10. Glad you got to see the comet. Was it easy to find ? That's an area of sky I can see from my garden so hope to have a go soon, if the clouds clear.... Were you out with the big dob? I've only got smaller scopes so don't know whether I would make it out. Here's to next time.. Mand
  11. Good luck for later Kain. Here is a link for comet lovejoy, if it works http://www.skyhound.com/sh/comets/2007_E2.gif
  12. Hi. yes, astigmatism will affect your sight without specs on. It causes two points of focus, so you may notice a ghost image type effect without specs. This is not too much of a problem for low amounts. If you have a copy of your spec prescription, look at the number in the 'cyl' column : a number of 1.00 or less is not too bad, especially if the 'axis' is 90 or 180. Robin, the 'older' eye (sorry), often has smaller pupils that take longer to dilate, so give yourself plenty of time to dark adapt. Glad to have helped, Mand.
  13. Well, I am an optician (optometrist), but an astronomy newbie. This is what I think: I assume the light rays exiting an eyepiece are parallel, so then distance correction is needed. A target shooter needs to be able to see the foresight reticule, reasonably clearly, superimposed on the target. Astronomers don't have this requirement, except for the polar scope or finder where you can sometimes adjust the reticule to look sharp when looking into space. The pupil size at night has no effect on specs performance, but can allow some aberrations of our eyes optics to come into play, and has a bear
  14. Can anyone suggest some objects for a beginner to observe during these coming months. I have a 4" refractor and 140mm mak, and have views from south to west above about 30 degrees upwards and south east -same height. Straight up is pretty good! I am aware if won't be getting very dark at all, but 11.30pm ish is latest during the week. Already done Venus and Saturn, but fancy trying to locate dso and using setting circles. Look forward to suggestions. Would software like Starry Night help me to decide what to see? I have 'Turn Left At Orion' on order. Mand
  15. Excellent Martin!, that's just what I've been trying to find after I came in. Many thanks for that link. Mand
