Anybody out there?

Hi John,

I think there are still a couple of us left here.

Not sure what happened but it must have been major!

Cheers,

Acronyminous Bibles

Hi Lee,

My preference these days is for the NIV. At least it is a proper translation and not a paraphrase. Another good version is the RSV.

A couple of questions

Posted By Maurice Clark

Hi all,

Thanks for the responses. Looks like there are quite a few extras I need to get. I just hope I can get them past the family treasurer!! 8O I will need the "T" adapter. The one I have for my Canon film camera is too small in diameter. sad

Regards,

Maurice

NGC2736 Herschel's Ray

Posted By Maurice Clark

Hi Greg,

A very nice image of a very neglected object. I stumbled on this one 2 years ago and was surprised at just how easy it was visually. Probably the easiest section of the Vela SNR to observe. It deserves to be better known.

My own piccie of this object is here : http://www.montgomerycollege.edu/faculty/~mclark/public_html/2736oz.htm

Nowhere near as good as your excellent image, not enough exposure time. sad You did a very good job with yours.

Regards,

Maurice

Magnitude

Posted By Maurice Clark

Hi Darryl,

Interesting question! You already have some good answers, and it really is a case of your own eye sensitivity and the viewing conditions. It is also very important to preserve your night vision. Even when using a red torch, it should be as dim as possible as even a red light does interfere to some extent. In addition, dark adaption continues to improve over several hours as the chemical rapsodin (sp?) is removed from the eye. So you can see more after several hours in the dark.

M33 should not be all that difficult from a dark site for most people. Stephen O'Meara and Timo Kahula are 2 that I know of who have seen M81, which seems to be the most distant object visible to the naked eye from the northern hemisphere. From the southern hemisphere, myself and several of my friends (including Timo) have observed NGC 5128 with the naked eye, and this seems to be the most distant object for southern hemisphere observers.

One object that I have not found any naked eye observations for is NGC 253. I would have expected this one to be observable, but despite repeated attempts I have not been successful. I wonder if the problem is that it is close to the zodiac light and this brightens the background too much? Any thoughts anyone?

If anyone has observed anything more distant than M81 or NGC 5128 with the naked eye or knows of any confirmed reports, I would be interested to hear of them.

Regards,

Maurice

Hi August,

As was pointed out, it really is a bit too magenta. Not sure if that is a result of the processing or the scanning.

I took the liberty of playing around with it in Photoshop. The results are below. Mostly it came out quite well, except for the bright stars. Could not get them to be the correct blue.

Cheers,

Maurice

Omega Centauri

Hi Thomas,

Beautiful, sharp image. I especially like the way the background galaxies show up so well. NGC 5209 to the bottom left is very nice.

Well done.
