Question 1

I was able to see Saturn's ring clearly with 4mm eyepiece .Can I buy one 2x barlow lens and that will magnify 200X. Is this supports 200x?

Accepted Answer

Saturn's rings are always a treat!  Glad you saw them.   A 2x barlow and 4mm eyepiece will give you 200x on this scope, which is about the theoretical maximum usable magnification for a 100mm aperture scope like this one (about 50x/25mm).  But in my experience with these smaller scopes, the image is rather poor at maximum magnification; you can see something, but very dim and very grainy, for instance. For my eyes, the max usable magnification is closer to 40x/25mm.....  I think it's fun to use the max magnification (esp. on the Moon!) But I usually get the most satisfactory viewing at a lower power.  Enjoy your telescope!

Question 2

What does it show for planets? Decent details? Or tiny bright circles?

Accepted Answer

With the eye pieces that come with it, we’ve seen 4 moons of Jupiter. The moon views are great too. It is best and easiest to see these details on a clear moonless, or next to moonless night. We added a 2x magnifier to the 10mm and it’s been a life changer.

Question 3

I can't see anything. Are you supposed to remove the black covers from the two ends of main tube?  Also don't see red light in the easy fixer device.

Accepted Answer

Yes, remove the 4" cover at the end with the eyepiece. Remove the entire 4" cover, not just the smaller 2" insert. The black cover at the mirror end should not be removed. On your easy finder, be sure you have clicked the rotary switch to fully on so the red dot is at maximum brightness. Try to line your eye up with the finder tube with your eye six to ten inches behind the finder tube. The red dot appears to hang in mid air and it is indeed not easy to see it at first. Keep trying - moving your eye around until you see the red dot. It's there, just keep at it. It gets much easier after you have found it a few times. It will all seem awkward at first, but gets much easier. Happy viewing!

Question 4

Hi what are the outside dimensions of the telescope without the tabletop base attached (so tube and viewfinder only)? Thanks!

Accepted Answer

The barrel length is 14.5 inches,   The outside diameter of the barrel is about 4.25 inches.   If you add the viewfinder &/or ocular holder, it adds about 2 inches to the diameter.    What is nice about this scope is that it can be put on a standard camera tripod.   But it should be a very sturdy, heavy-duty tripod.
