Re: Laser pointers

Hello All. I have owned a 1 mw and 2 X 5 mw. THe latter seem a lot better. In reading Brian's comments of shining the laser down the focuser, I have shone it down the finderscope and it does appear in the sky. And the comments about the cold are very true. The last one I purchased on ebay for a few ...

Colin. I would suggest you need to unbolt the rigel finder and what ever is left on the telescope is the bit you need to buy another of. The other job you will need to do is align the finder each time you swap it over, and the shoe/foot will not be in exactly the same position on each scope. Is it n...

If you google you will find people have been putting telescopes into lofts here and there, even though mounts are bolted to solid beams they seem to complain about vibration when imaging. If you are just going to use a telescope for visual use, then what you are going will be fine. If you are going ...

I have to say one of the issues you will come up with is having to have a column of some sort through the ground floor to the first floor. People have done it, but the longer the pole the more the flex for the telescope on top of it. And I suppose the existing building would not lend itself to modif...

You did not say, or I did not see, what the damage is, if it is limited to either the mount or the telescope you could put the money towards just replacing that part. If you are going to replace it all, my comments would be buy secondhand. Astronomy is a hobby which only seems to attract honest peop...

Barry. I have not used one, but tried making one. I would have to say I think it would make sense if you had a big dobsonian and the cost of buying a GEM mount would be very expensive due to the weight. If asked, for a 10" dob I would go down the GEM route, which would give you the option of GOTO, u...

Hello David. I have found this link http://geogdata.csun.edu/~voltaire/classics/ which will no doubt be of interest to many but it does not have the right year for me. I think both scopes would have been very expensive. I go back on Monday night, so pictures after. And they have an old C14 in a clas...

David. Thank you for the reply and sorry for not being detailed enough. I suppose the question is does it make much difference being in doors rather than outside? I know the view would be limited, but if we took this to its furthest option, if you had a glass dome, could you sit outside but in the w...

David. Thank you for your very detailed report on the binoculars you have purchased. I understand why you are observing from inside your house but are you able to explain the effect the window glass has on this? I think with two sides of a pair of binoculars you can establish the features you list a...

Fullerscopes

Dear All. I have found a book on the internet written by Douglas Fuller about (i assume) fullerscope telescopes. The book is from 1972. Has anyone out there ever seen it?

Brian. In an uneducated reply to you, I would think the cost of recoating a mirror with the conventional covering is so cheap and lasts such a time that unless what you have is more reflective, there would be no benefit to it. Now I will have to google "dialectrically-coated " to see how far off the...
