What EPs would be advisable to go for? Currently have a 6mm and a 20mm

Yes they are Huygens. After a look at Nipon Scope I could splash £50 on payday and get the diagonal/image converter and a few eyepieces to try out on next doors cat.........

Without knowing what specific eyepieces you have it's difficult to comment. There were some very good quality 0.925" eyepieces made, but there were an awful lot of basic, low quality eyepieces made as well. I know you mentioned that the ones you have are replacements, but the ones which originally came with my Prinz Astral 400 were rubbish. I upgraded to some 1.25 Plossl eyepieces and it made a big difference.

If you did want to upgrade your eyepieces, there is a vastly larger range of 1.25" eyepieces available, so an adapter/diagonal would give you that choice.

All I know is theres a 6mm, 20mm and 2X Barlow, possibly what came as standard I guess. Its just clicked what the diagonal is so I understand now. Diagonal is what the eyepiece sits in and connects to the scope.

I would go for the 0.925" to 1.25" diagonal rather than tbe adapter.

I bought an adapter for my Prinz Astral 400 but, owing to the short focus travel of the scope, I found that I couldn't focus on anything further away than the back of the garden. Despite getting some very nice views of next door's cat I had to saw an inch off the end of the telescope tube in order to focus on the heavens.

What advantages would this give me over what I have at the moment?

Bearing in mind that at the minute my knowledge of eyepieces extends to "its the bit you look through to see the shiney thing"

Toughest part was stopping the scope wandering, tends to drift slightly which makes it awkward. Couldn't make any detail on Jupiter out, just fuzzy which was a shame but great at the same time. The sun eyepieces are staying in the box. All in all a fun little session

Awesome! Finally a break in the clouds so set it up an aimed for the moon. Eldest son was suitably impressed with the detail in the craters.

Tried to lock on to Jupiter which was really difficult. After about 20 minutes got it in the eyepiece a day although blurry it appeared to have a black dot/shape/shadow in view. A moon or dust in the eyepiece?

Thanks all. Just set it up and it wasn't tricky at all. The only thing I need now is a clear sky and we all know the problems in that department.

Well just picked it up and it looks like I've got a Sunday afternoon of figuring out what goes where as it's disassembled.

At least I've got a picture for reference

To calculate what magification your lenses will give divide the focal length of the scope (700mm) by the focal length of the eyepieces (6mm or 20mm) so this will give 116x and 35x but the barlow will basically double these figures.....so in theory you can use the barlow with the 20mm eyepiece to give 70x magnification but it won be worth doing this with the 6mm lens as this would give 232x which is way above the limit for your scope.

Hope this helps, and enjoy your new toy.

Couldn't have asked for a better explanation. I tried to explain aperture to a friend once, smaller number bigger opening etc. Didn't go well.

I'll avoid looking directly into a nuclear furnace then, probably best.

The eyepieces are new on me so the 6mm too high/low is a mystery at the moment. Guess I'll be getting my head around that soon.

Picking it up tomorrow so I'll no doubt have a great view of the clouds for a few weeks

Part of it was impulse, part the wooden box and part tripod for stability as Im struggling to get the tripod sorted for the binoculars. Eyepieces are new on me so I guess I'll do my usual fiddle and see what they do.

I know its not going to give Hubble a run for its money but I won this on Ebay today

Vintage Greenkat Japanese Astronomical Telescope

Circa 1970's - a collectors item

Has a 60mm diameter lens and a focal length of 700mm

Comes with two replacement eyepieces in good order in plastic cases - 6mm, 20mm, two sun viewing lenses and 2X Barlow

In very good condition, complete with tripod and wooden case

all for the princely sum of just under £12.52.

Its just to get used to tinkering with a scope I guess. At worst if its rubbish its something for the kids to try out and I get a nice wooden box to put stuff in.

What could I expect to see with this in comparison with my 10x50 binoculars?

(Un?)fortunately its gone so Ive directed my attention to a vintage Greenkat on Ebay. I know Im not getting anything amazing but if I get something for £10 Im not really going to lose. Greenkat anyone? All I can find is 60's 70's and Japanese, doubt theres much more to know really for that price. Its in a nice wooden box with tripod and

Theres a Taco for sale near me, very cheap. Anyone shine any light on it?
