This is a question for Mike - Would it be at all poss to post anything taken from your D70 at various Headcorn Weekend's - I'm very close to parting with £500 for an EOS 300D & it would be good to see the type of things you managed to get using a regular tripod at a dark site. I'm interested to see the type of mag's you could record.

Cheers,  John

John,

Will post some up tonight if possible. The 300D is a good camera and has produced some excellent results. The Nikon D70 that I use is comparable in its results, but it is a better all round camera with far more control over exposure, etc.

OK John, here are 3 pics from the Feb 2004 DSC :-

These images have not been processed apart from having an equal exposure dark frame subtracted to remove the amp glow. They were all taken unguided from the top of the ETX125 on an approximate alignment.

I haven't tried to find out what mag they go down to but there is certainly lots of stars!

(p.s. the focus is slightly out as they were done visually and not through the laptop)

Thks Mike - I managed to take a look at a few of them (Very slow download for some reason even with my 1Meg BroadBand)- Like you said lots of stars. I'm convinced I need one. I'll go for the Canon though as I already have lenses & the pennies are less. I don't think lack of manual settings will effect ability to take Astro-photo's although might be of benefit for normal pics.

Cheers,  John

The pics are being served from my home server. As the bandwidth is also used for downloading stuff it won't be particularly fast.

there like really wide field!

Mike

Exactly - Even attached to a scope the image is wide field. Which is great if you want wide field, but it means you have to put some heck of a magnification to get close to anything.

Just ordered a 300D - Can't wait for delivery - should come Monday.

I did a quick calculation on FOV & I reckon that when I put it on my Tal-2m (1200mm F/L) I should get about 1deg X 43arcsecs & when I use the 135mm lens that I already have I should get a whopping 9deg X 6deg...!
