Remarkable deep image from ESO

Posted By Maurice Clark
Hi all,

Thought this image was worth linking to. It is an incredibly deep image taken at the ESO. 40 HOURS!!!! 8O of exposure at UV plus blue and red. Apparently it is the deepest ground-based image obtained yet.

You should download the full resolution version of the image (warning 32MB!) The detail is amazing and the number of galaxies in the image is insane!

The link below takes you to the information about the image. To get to the actual image, click on the thumbnail.

Cheers,

Maurice

refractor suggestions

Posted By Maurice Clark
Hi all,

I have a problem. I just received an email from the mother of a former student who will be graduating as an astronomy major in May and wants to get him a telescope as a graduation present. I know he has been having fun up at mecca (AKA Mauna Kea.... lucky $#$#@$# studying at UH!) using the refractor at the visitor's centre for astrophotography, so my thoughts would be for a compact refractor, about 4". Only one problem... the mother is wanting to keep the cost down to around $1000 - $1500, and from looking around here, a reasonable 4" plus mount would be well over $2000. :-(

Does anyone have any suggestions?

Cheers,

Maurice

Hi all,

Do not know who this person is, but he had me cracking up! Not only because what he said was so funny, but because it was so true!

Alan Stern piece in NY Times

Posted By Maurice Clark
Hi all,

Here is a link to a very interesting piece by former NASA associate administrator Alan Stern concerning the cost increases in NASA missions and their effect on other missions.

Quite interesting.

Re: Out of gas

Hi Jim,

Interesting question. In Australia the govt offers a $3000 rebate for anyone converting a car from petrol to LPG (from a cost of about $3500). Petrol is currently around $1.40 per litre against LPG around $0.45. So many people are converting their cars. I have just bought a car already converted for this reason.

So what happens if you run out of LPG? (assuming you did not bother to watch the fuel guage) You just flick a switch and you can run on petrol. So I always keep the petrol tank about half full as my emergency. Half a tank will get me about 350km which should be enough to reach a fuel station! grin

Hi David,

Frank Borman was the one who chose the reading after a suggestion from
Joe Laitin, a friend of one of Borman's friends.

All three astronauts took turns in reading a section as part of their christmas message to Earth.

A couple of questions

Posted By Maurice Clark
Hi all,

I have finally given in to the dark side and joined the 21st century! Turning pensioning off my old faithful Olympus and Canon film cameras and going digital.

I have purchased a Canon Rebel XT modified for astro use. I believe I will need an adapter to connect it to my scopes as I understand that a "T" adapter for a film camera will not work, but what other items will I need for long exposure astrophotography? Cable release? And how long will the batteries last? Any information would be most appreciated.

Regards,

Maurice
