I was just viewing Mirach's Ghost ( for the Moore winter Marathon) when my wife came outside to tell me the sad news. Been a fan since the eighties and feel a little like the universe is now a much smaller place. Rest in Peace Sir Patrick.

Hi Luke(?)

It was quite simple really, Have a look at the previous picture and now look at this one. There was a inner tube which had been pushed in for transit, when I picked it up at the boot fair. I was trying to remove the ineer ring to bodge a 9" extension tube when the ring twisted out with a brass extension tube attached!!

Ok, do I measure the focal length from the ojective lens to the point of focus and add on a bit for the diagonal?

Hi John

Just measured the diameters and it will take both but with an adaptor for the 0.965" but the 1.25" needs no adaptor. So going for a Plossl What size would you suggest to get a bit more magnification?

Thanks John & Luke,

I will need to measure the diameter tomorrow and post it up for further advice. BTW I paid £35 for the lot!!!

Speak tomorrow,

Cheers,

Chris

Here is a picture. No names on it at all!!

Hi John,

OK not sure what make it is. Have al ook at my first thread "newbie and refractor advice needed." (or something like that) posted last Friday.

A ha the lower the number the greater the magnification,. I use an adaptor ring which fits lenses in the focus tube.

..Just wondered about this. I have been observing Jupiter and moons and can just about make out faint bands on Jupiter. I have some naff lenses, an H20 and a K12.5. oddly enough the k12.5 gives a more magnified view. I thought a 20 mm would increase magnification??? It doesn't appear to.

Pretty dissapointed with Andromeda as very faint so I am not expecting anything deep space as it seems too slow. What lenses would suit a slow old 60's refractor to make things more worthwhile?
