You mean like this? linky thingy

Stu, thanks for the link. Francis

Will we be able to blow up Nibiru before it hits earth? If they ask that I making them all placards and A boards to wear saying "The End is Nigh" :D

Are all astronomers far-sighted?

I got into photography through an interest in astronomy and have been doing astrophotography for 20 years. It's possible to get good pictures with fairly simple gear, your Canon should be very well suited to it. Manual exposures are what you'll be needing almost all the time, as cameras find it difficult to meter such things as the Moon. A full Moon can often be captured well with an exposure o...

LAF: I can't say I agee with everything you wrote, but I did love your last quip and oh how true. I do think JohnHorne is correct, I think it was his little brother Jeb. LOL

This instrument is designed for visual use, rather than photographic. Long exposures would not be feasible as it's an alt-azimuth mount. You could probably get reasonable lunar shots in prime focus mode (camera attached with t-mount) but watch out as I don't see any way of attaching a couterweight. You could also probably get reasonable shots of planets by simply photographing handheld through...

LOL Steven! ;) My aunt was the one who got me hooked into astronomy - still fascinated. Didn't have binoculars or telescope but used to stargaze and read and read and read ... Wish I'd thanked her for that .. 8-D

Check This out Bri, it might give you some idea of what you are looking for.

You are obviously going to attach your camera to an astro telescope. This can introduce major complications - and is something few DSLR owners do. If your telescope does not track star movement you will get significant blurring due to the earths rotation during a 30 second exposure. It is unlikely that a beginners level DSLR will function normally with an astro telescope as there are no elect...

The last in the series tonight... 8pm on 5 :)

"CO2 Science" is funded by Exxon. The move to unleaded petrol was delayed for years by scientiests sponsored by the petrochemical industry. Just hope history is not repeating.

Hmm the biggest i dnt got a mere 500mm but as for best lens//// MY EYES :D for without them id see nowt.

I bought a telescope at the beginning of this year - I can recommend the Skywatcher 127 on a computerised 'GoTo' mount. I've struggled with imaging though. Mainly down to focusing issues. It's more involved than you might think. This is a good site with a lot if useful info and a bunch of friendly contributors. Dave

Stuart, reciprocity failure is caused when films are exposed for long exposure times, the effects being: (1) an effective decrease in film speed, so for example if a correct exposure is 1/15sec at f1.4, you would expect 16sec at f22 to give the same exposure, but you would actually need a longer exposure time. (2) and this is the bit relevant here, the colour balance also falls to pieces,...
