Your scope should have come with one or two eyepieces that are then inserted into the focuser. here is what an eyepiece looks like they come in 3 sizes, .965, 1.25, and 2 inch. MEASURE the hole in the focuser.

Unless you have a lens collimator and other equipment necessary to ensure proper alignment when you reassemble the lens, please don't try to open up the lens yourself. This is more than merely a "very good lens" and I would hate to see you ruin it. Instead, please take it to a good camera shop and have a qualified and trained technician do the work.

Missing parts to galaxsee tasco


eye pieces are interchangeable and you will want a few of them for different magnifications.
The previous owner probably got a new scope and kept them for that.
Here's where I go for lens' in Toronto Canada.

The rule of thumb is cheaper eyepieces are ok for the low magnification 35mm-20mm but as you get to higher magnification a better eyepiece will make more of a difference. How expensive is up to you and how serious you are into this. I think my better lens was a used tele-vue for $80

With a 12X lens, if you put a 1.5X converter on it, there will be very little visual difference in the magnefication.

With a teleconverter, the lens will lose some F stop, and the optical image will be a little less sharp.

What lens do i insert into scope to view the moon


The moon is big so use the 25mm. The Barlow will have a multiplication marking on it 2x 3x etc. A 2x Barlow lens will effectively double the power of the eyepiece you are using. Do not use the erecting eyepiece for anything other than land viewing. Erecting eyepieces generally reduce the amount of light reaching your eye and thus reduce brightness of the faint objects in the sky.
So basically just place the 25 mm lens in the focuser and point the scope at the moon and you will be amazed at what you can see and how bright it is.

Dropped Camera Zoom Problem


Afraid not a novice or even an expert can fix this one. It will have to be a repair of the zoom mechanism. It will almost certainly be costly. Check your Olympus support site to see what your local repair options are.
