  1. You can get 12v USB chargers for Ipods, phones etc.
  2. I was searching through E-Bay at the ccd cameras and found these.... http://cgi.ebay.co.uk/Sony-Chipset-1-3-CCD-CCTV-Color-CAMERA-True-480L-8Lux_W0QQitemZ160131710431QQihZ006QQcategoryZ48632QQrdZ1QQcmdZViewItem http://cgi.ebay.co.uk/NEW-1-3-SUPER-HAD-SONY-CCD-CCTV-CAMERA-480TV-0-01-LUX_W0QQitemZ180132484764QQihZ008QQcategoryZ48632QQrdZ1QQcmdZViewItem http://cgi.ebay.co.uk/New-Wired-CCD-Vidicon-Sony-Color-Spy-Camera_W0QQitemZ140133352969QQihZ004QQcategoryZ48632QQrdZ1QQcmdZViewItem http://cgi.ebay.co.uk/402C-CCD-spy-Color-video-wireless-Pinhole-Camera-UK79_W0QQitemZ290131084896QQihZ019QQcategoryZ48632QQtcZphotoQQcmdZViewItem http://cgi.ebay.co.uk/Wired-Color-CCD-3-6mm-420L-Bullet-Camera-12V-UK326_W0QQitemZ290131075221QQihZ019QQcategoryZ48632QQrdZ1QQcmdZViewItem Just out of curiosity would these be any good for astrophotography. They are all Ccd cameras that can be hooked up to a monitor or TV. They are pretty cheap and I was just wondering. Mick

    HI From West Sussex

    Hi Ed welcome to SGL and enjoy your stay.
  7. Same here. 11.30 and the sky's clear of cloud but I counted 12 stars.
  8. Wow this is an inspiration to me. I thought you needed mega equipment to do this. Unguided shot you did very well.
  9. Excellent shot. Really sharp with great colour. Thats one fine scope considering it's size.
  10. Good question Ant which I would ike to add another to..... If like Ant said he had to do 50 dark frames why can't he just do one master and copy an extra 49 in photoshop. Is the same as covering your telescope lens 50 times. One more question. Are the 50 lights and 50 darks added together into one photo then subtracted?
  11. Maybe some really knowledgeable person could write up an idiots guide to dark frames
  12. Hi Gren hope you enjoy your stay..
  13. I'm finding it hard to get my head around dark frame subtraction. To get dark frames I just block light coming into the telescope is this correct? And the total exposure of dark frames must equal the total exposing time for the given object? I understand the theory behind noise etc but isn't dark frame subtraction essentially like using your in camera noise reduction or a third party software such as noise ninja Also when are the dark frames subtracted? Mick
  14. Hi Steve. The Canon shot definately looks better. Stars are sharper, there's better colour and overall the Canon is alot better to look at then the Meade. I have read a few articles saying that ccd chip are a lot better than a cmos chip. I believe that the Canon has a cmos chip, which is confusing as lots of people rate it and it does take excellent photo's. Is it that cmos chips are very good for short exposures that require stacking while ccd chips are expensive but great for longer exposures. Steve how do you guide your DSI is it with the meade software or some third party make such as guidedog?
  15. Cheers guy's loads of great ideas. This is definately going to be a learning curve So I'm definetly going to go for an EQ6. It seems the norm for photography. Scope is a toss up between Orion ED80, Skywatcher ED80 or my favorite WO Megrez 80 APO. The last only for the build quality. Any of these should do a brilliant job. Has anyone any feedback on the Meade DSI camera? Kaptain which Webcam do you use. I've been reading about the Toucam 840K Pro 11, it seems really good. Do you use Guidedog when you use your webcam to autoguide? And also would a IR block filter have to be used on this webcam? So many questions.... Mick
  16. Thanks Phillip. Why do people rate the Canon 350D so much is there a special reason?
  17. Doc


    Great capture....
  18. Sounds like great fun. Really looking forward to trying this one day. Mick
  19. I have spent the last three days reading about astrophotography, the more I read the more I think this could be for me. I would like your opinions on this set up that I have in mind. I will have a budget of approx 2200 pounds. EQ6 Pro Synscan. Either a WO Megrez 80 Apo or a WO Megrez 90 As for a camera I need help. Can anyone advise on a good camera about 200 pounds. What can I expect in the way of exposures with the above set up. Also do I require anything else. Btw I have an old laptop that I can dedicate to the set up. I did think about the WO Zenith 66 as a guide scope piggybacked on the 80 or 90 but that can come later. Cheers Mick
  20. As far as I now the 3000 series have 4 elements, the 4000 series have 5 elements and lastly the 5000 series have 6 elements. Also I think the more expensive you go the wider the field of view is. This is only off the top of my head as it's something I have read in the past.
  21. Starhopper I know where you mean very well. Thats only about 2 miles from me. If you need any help just ask, quite new myself but two heads are better then one.
  22. Welcome Fern. Enjoy your stay at SGL
  23. Another vote towards the ED80 from me. For the money seems like a little cracker.
  24. Well done Martin... It's a lovely shot. You can really see the colour and bands. Mick
