Crescent Nebula in Ha and OIII

Posted By Maurice Clark
Great shot Ron!

Just one question. Does your OIII filter have a red leak? If so, how did you stop it? I tried some images with a lumicon OIII filter once but there was just too much red (infra-red?) light leaking through to be useful for colour.

Cheers,

Maurice

Binoscope vs. One Scope

Posted By Maurice Clark
Hi Chuck,

A binoscope shows fainter objects and more detail than a single scope, but not for the reason you might think. There is no increase in lightgathering ability, as each eye still only sees light from one telescope. However what does happen is that the brain now recieves 2 images of the sky. One from each eye. The brain then compares the 2 images and rejects anything that is not in both images. Therefore a lot of the "noise" that is in the view is rejected, allowing more of the image to be viewed. I am not sure of how much you gain, but as a guess it would probably be a couple of inches. "Sky & Telescope" magaziene ran an article on the advantages of a binocular scope many years back, so it might be worth trying to track it down.

Hope this helps.

Four Corners Leonid Report

Hi Charlie,

The International Meteor Organization and the American Meteor Society are 2 organizations that would be interested in observations. I do not have their Web addresses but a Google search should supply those without any problems.

Cheers,

Here in southern Mionnesota we had a good show. Skies were not good, bright moon and cirrus. Activity certainly picked up after 4.15 CST. I observed 181 between 4.30 and 5.30 (less about 15 minutes for camera breaks). The wife saw 121 between 4.50 and 5.25. Considerable 'bunching' with as many a 6 within a couple of seconds. Rates were dropping off after 5.15. Saw 'only' 23 in the final 15 minutes. Not a real storm, but after missing last year's show, it was the best display I have seen.

Quite a few of my students came out for a while and seemed to enjoy themselves. For most though the sight of Saturn and Jupiter through a telescope for the first time was the hit of their night!

Cheers,

tester for web deep sky planner needed

Posted By Maurice Clark
Hi tom,

I tried your planner but it would not let me set a latitude. Also when I entered central US it still gave me objects like the Magellanic clouds as being suitable for viewing. It also indicated a latitude of 95! So there are still some bugs in the system I am afraid.

Keep trying, it looks like it could be useful.

PS the NGC number for 47 tucanae is NGC 104.

You should also have a look at the "CCD University'" at the Apogee website. The URL is http://www.ccd.com. A lot of very useful information on choosing and using a CCD.

Hi Gary,

As a professional scientist (physics/astronomy PhD) and a Christian, I find your comments amazing! Obviously you have never given Christian beliefs a serious study. If you had, you would never make such an illogical statement.

PS Try a spell-checker next time you post!

The Poms finally have a win!!!

Posted By Maurice Clark
Of course!!!! Got to try and get some real sport in here!!! :^) (tongue very firmly in the cheek here!)

Actually I have tried watching the American football since coming over here, but I cannot get into it. They seem to spend most of their time standing around in a huddle having a chat! Even slower than cricket!!!!! (Ducking for cover!!!) :-)

Cheers,

Maurice
