Infinity 76 Quick Question

[Buckles]

Hi folks,

I have recently bought my son the Infinity 76 for his birthday. We took it out last night and got a gander at the moon and Jupiter - the latter of which was no more than a fuzzy white dot. To enhance the experience, and fuel my son's now abundant enthusiasm in astronomy is there any kind of lens I can buy to replace or enhance the 30x mag of the one that came with the Infinity 76?

Regards,

Buckles

Hi Buckles

I have the same scope for my children and the supplied eyepieces use a helical focus method. If you carefully remove the two plastic lugs in the focuser (they just slide out) then you can use standard 1.25" eps. I wouldn't attempt to get dramatically higher magnification but probably x50 or x60 would be ok so something like a 7mm or 8mm would be worth a go.

Cheers,

Stu

Hello,

Not unless they've changed the design!

Does it still have a screw thread to gain focus?

If so, then unfortunately not.

Sorry

Scratch that then, I stand corrected!

Cheers

The Infinity 76 is a difficult scope to upgrade by the look of it, I did a search and found an EP that can do 50x, but read the buyer reviews first here: http://www.telescopeplanet.co.uk/50x-eyepiece-for-infinity-76-youth-telescope

Just a note - I had one a few years ago and was never able to get a decent view of Saturn's Rings with it. 30x was not enough to resolve them and the 50x erecting eyepiece supplied with the scope was hopeless.

Thanks for all the feedback, now time to mull over the suggestions and peruse the links.

Maybe I was over optimistic with a 7mm. 10 or 15mm may work. Basic point is that the mirror isn't to bad, but the supplied eyepieces are a bit rubbish, so using better quality ones will. No need for anything too expensive obviously.

But isn't it a 10mm that's supplied with it if it's x30?

And the x50 would be a 6mm?

As always, I'm happy to be wrong.

Yes, it will be. The point is that a better quality ep will give better results. I thought the focal length was 380mm, but remembered wrong, it's 300mm isn't it. Maybe try a 7mm giving x42. To focus you will just have to slide the ep in and out, not ideal but it works.

Now I think about it, I tried a 7mm Nagler in mine and the results were quite good. No need for anything like that, a simple but decent quality Plossl is worth a go.
