Just thought i would let every1 know that its too cold to look at the
telescope and that i miss the moon. Well when it gets warm i am going to go moon gazing again and i wish i could see jupiter and saturn. I got a big telescope with those computer control box things and im going to learn how to use that. Not that anyone cares i know. One question is how do you look at the sun ? I mean how do you look at the sun through a te;lescope without going blind ? Because i could probly do that from inside the house. Holly |

There is 2 ways to use a telescope to look at the sun.
1. Mount a sheet of white cardstock above the eyepiece and PROJECT the suns image on the cardstock. I do this with my 8inch Dob and it's the safest way to do it. 2. But a full apature solar filter that goes over the front end of the telescope. -- "In this universe the night was falling,the shadows were lengthening towards an east that would not know another dawn.

My exciting image of the sun grew hazy as smoke started to pour out of my eyepiece holder. 2. But a full apature solar filter that goes over the front end of the telescope. This is a much better choice. It allow you to observe the sun directly. Glenn Yes. Projection, is fine, _provided_ you really know what everything in the light path is made of, _and_ you keep it aimed well. In the case of a Dobsonian, provided you don't have eyepieces with plastic mounting rings (becoming rarer rapidly...), it is OK. If you aim slightly 'off' with the Newtonian scope, the image misses the secondary, and is safely formed in front of the body of the scope. On an SCT. it can damage the bottom of the baffle tube, if the scope is not kept well aimed, and there have been reports of cracking the corrector plate, if the heat is allowed to build up.... Normally refractors again work OK, but will heat rapidly, if aimed 'off target'. The full aperture filter, is very cheap to make now (with the Baader astro-film), and works well. The general rule, is be very careful, and know what you are doing, before starting. If in any doubt about safety, _don't_... Remember to cover the viewfinder scope. Best Wishes |

There is a caution concerning solar film usage that should also be
mentioned. Yes it is cheaper, but you must check it every time before use for pin holes. "CLT" not@thisaddress wrote in message ... "Holly" wrote in message ...

I've been told about that buring bit, BUT in the many MANY hours that I've spent
looking at the sun's image with my Babylon 8DOB with it's OTA turned upside down and the ONLY thing that has happen was when I left my moon filter on an EP and it broke. But otherwise nothing has happened, no melting, no burning, zip,zerro,nadda. And I also have used my Stargazer Steve 4.25in F9 Dob to do the same thing and once more nothing has happened. So if yours melted, you must have had an awefull cheap one. -- "In this universe the night was falling,the shadows were lengthening towards an east that would not know another dawn.

Hi Holly,
It's never too cold to observe. You simply need the proper clothing. I have an illustration of what the well-dressed observer wears at http://home.att.net/~dpersyk/new.htm Not very chic, but it does keep me warm in 0 F, -18 C weather.

Hi Holly, There is actually a third way, which is to use a hydrogen alpha filter. One of the best companies making these today is Coronado. I had without question the most fantastic views I've ever seen of the sun though one of these. http://www.coronadofilters.com/ |
