Hello, I am about to purchase my first real binocular telescope. Currently I own a 25x100 Celestron but I am not very satisfied with (the only advantage was it was quite cheap).
I narrowed my options down to those two:
1) APM 100 mm 45° ED-Apo
2) APM 120 mm 45° SD-Apo
I would like to ask any people who have first hand experience with both telescopes, to help me decide.
What I need to observe?
Mainly low-light terrestrial objects (evening) but sometimes also galaxies and planets.
What is the main thing I am looking for?
First and foremost: sharpness and fidelity.
What magnification will I usually use?
Anything in the 50x-65x range.
Let me point out that I do know that the 120 mm BT is going to be a lot brighter than 100 mm.
My main question now is: Is there any noticeable difference in sharpness and fidelity between the two BTs when the magnification is in the 50x-65x range?
If not, one should probably go for the 120 mm to get a brighter image, which is always good to have. Am I right?
Weight or mobility is not a problem. It is going to stay in the same place.
I read that ED APO is higher quality (sharper?) than SD APO. If that is true, it might make the 100mm a better choice, mightn't it?
Also, do you know any better binocular telescopes than those that allow for 65x magnification and cost about the same?
