How good is a Questar telescope?
There are a few niggles, but overall the Questar is a design that has survived because it offers what few other systems (perhaps no other system) does – a complete high-quality observing system in a carry-on case. Yes, it’s a smart astro’ status-symbol, but a very useful tool as well.
What magnification telescope is good?
For most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×. And even then, you’d need to wait for a night when the observing conditions are perfect.
What type of telescopes do professionals use?

Are Questar telescopes still made?
Questar was founded in 1950 by Lawrence Braymer, who set up Questar to develop and market Maksutov telescopes and other optical devices for the consumer, industrial, and government customers. The Questar Standard telescope has been in production since 1954.
How big of a telescope do I need to see galaxies?
If you want to observe galaxies — and I mean really get something out of the time you put in at the eyepiece — you have to use a telescope with an aperture of 8 inches or more. Bode’s Galaxy (M81) glows brightly enough to show up through binoculars, but the larger the telescope you can point at it, the better.

Is Vixen a good telescope?
4.0 out of 5 stars A good quality telescope. This is a well made, nice looking scope that can deliver interesting views for the beginning stargazer,or one who has limited time,budget,or strength. You do need a mount and tripod or other support. The included eyepieces give about 45 and 142 magnification.
Is the Tele Vue np127 a good scope?
The Tele Vue NP127 is a f5.2 flat field four element apochronatic Nagler-Petzval design five inch refractor. It’s touted as a multi purpose scope which can show you from low power wide flat fields of DSO to high power planetary views. A jack of all trades, master of none?
Is the Televue 101 the best scope for You?
Anyway, the unit on the Televue 101 is well known as being an excellent focuser, and it works well with everything from my 31mm Nagler to my 4mm Ortho. While Televue calls this scope the “101”, it actually is more like 101.9mm. I am SO happy to have that extra .9mm.
Is the Televue focusmate worth it?
For telescopes that have a greater depth of field it works wonderfully. On the faster scopes however (like the NP series) a two speed focuser is definitely appreciated. Enter the Focusmate. The Focusmate is an add on fine focuser for, well, nearly any of the telescopes sold by TeleVue in recent history.
How good is the Televue 102 compared to the Genesis?
If anything, the 102-Gibraltar combo was even more stable than with the Genesis, the longer tube of the 102 contributing to easier leverage of the scope in altitude. My assessment of the optical performance of the Televue 102 was carried out over a period of six months.
