Hi Cliff, I too get odd colour with the MX5-C but I usually just fiddle with the colour balance controls to get the pointer at the same point on the histogram for each colour, R, G and B. As long as the stars are white then I can't have it too far out! I think the comet's colour is real (ie not gene...

Here's a picture taken 31 Dec using the MX5-C and a 50 mm focal length lens. The fan-shaped tail is now becoming easier to see. Curiously, the cyan colour is very strong when photographed with this camera, but virtually absent as photographed with my Canon 10D digital SLR. Robin http://homepage.ntlw...

Thanks Neale -- sounds less painful than completely reformatting the drive (and hence having to reinstal every bit of software). I'll keep you posted!

Cheers

I only wish I could get my Toucam (740) to work again! It has been checked on a friend's computer and works OK, but on my own laptop it refuses to work -- I just get a black image. Something in the software is wrong -- probably nothing to do with the Toucam software itself, which thinks the thing is...

As I have mentioned in the other post on this topic, full details of the 2029 NEO approach are given at http://neo.jpl.nasa.gov/news/news148.html However, the conspiracy brigade will no doubt say that that this is a whitewash anyway, so there's not a lot of point in even mentioning these stories or ...

The 130M is excellent value. The eyepieces are Kellners, and actually aren't all that bad. It's the Barlow that is poor, but even with that I got good views with a test model I tried -- rather too much false colour, but I could still use it. I only wish I had a telescope as good as this to start wit...

Err... T & S? Don't recognise the abbreviation. I'd have expected a 10" to be the full 10", though if the manufacturer advertises it as a 10" they could argue that it's a nominal figure and they should then give specifications that quote the exact mirror diameter, in which case I ...

I've just been looking at the comet and taking a few more photos. For anyone unsure how to find this comet, it really is quite easy: just find Rigel in binoculars and look to its southwest. It is quite large and easily visible even though it's not particularly high and tonight there was moonlight. I...

Here's a picture I took with a Canon 10D and LX90 Schmidt-Cass (200 mm) this evening at 23.08. Two 20 sec exposures combined. Sorry about the copyright line but I don't want it pinched!

We do have a Computing Adviser but he says he gets very few questions. What 'Stella' means by computing is possibly more to do with calculating the orbits of astronomical bodies than the general application of computers. If there is a demand for any of these sections, then please everybody YELL! Oh,...

Back numbers of S & T, Astronomy, Astronomy Now

This message is also posted in the Classified section but I thought I'd put it here for maximum coverage as well. I've been told that the London Planetarium have back numbers of these magazines going back to about 2000, though not every issue, which they have to get rid of because they need the spac...

Back numbers of S & T, Astronomy, Astronomy Now

I've been told that the London Planetarium have back numbers of these magazines going back to about 2000, though not every issue, which they have to get rid of because they need the space. They are keeping the 2004 issue for the time being, though. If anyone wants them (free) and can go and collect ...

>Really stupid question, but do you attach them to the scope, tripod or hand?? You attach them to the scope, and adjust them to point exactly where the telescope is pointing. Then when you switch it on you see a beam pointing up into the sky which is exactly where the telescope is pointing. Here's a...
