Not as nice as Geoff's, but I thought I'd toss these up here anyway, as they were taken with the same model camera (little compact digital in an afocal approach), but a much smaller telescope.

Camera: Canon IXUS 70 compact digital (7MP)
Exposure: ISO 400, f 4.9, 1/15th sec.
Scope: 130mm simple Newtonian reflector, f/5
Flimsy end of the spectrum equatorial mount (EQ 2 or 3?)
Motor drive disabled
10mm eyepiece + 2x Barlow + neodymium filter

Seeing sucked, and not that the moon isn't bright enough, but it was within 15 degrees of a sodium streetlight 20 metres away.

I got a little carried away and labelled a few craters... :-)

Cheers,
Chris

P.S: Is there any chance of increasing the allowed image size to something a bit bigger than 200KB?

Nice work Chris, good images.

200kb is generally plenty for most shots, as long as you reduce the resolution before saving for web (which you've done).

Photoshop "Save to Web" or Irfanview or many others let you select the compression so you can avoid artifacts.

If you've really got a hi-res photo, you can just upload it somewhere and link to it.

Cheers

Well done Chris,
It is great to see your enthusiasm, going the extra step with the labeling at least shows that you have taken the time to research your subject, I like it.

Also, with these images, you have demonstrated to others that nice work can be done with basic equipment.

Congratulations
Regards
Trevor

Is there anywhere online with an absolutely definitive list/map of all named features on the near side of the moon, by the way?

I'm not holding out much hope that there's anything I can see that hasn't already been named, I'm just curious. :-)

Hi Chris,
Not sure about on the net but Antonin Rukl's "Atlas of the Moon" is the best reference that I know of. It is published by Sky Publishing Corp / Cambridge, Massachusetts 2004, ISBN 1-931559-07-4.

I purchased my copy through Australian Sky & Telescope, I think it would be at Bintel also.

Regards
Trevor
