Is the Celestron C-6N Reflector a Good Choice?

AI Thread Summary
The Celestron C-6N reflector is noted for its affordability and decent optical performance, but it has significant drawbacks. Users report that the mount is undersized and unstable, often requiring upgrades like sturdier wooden legs for better stability. The optical tube exhibits coma at lower magnifications due to its F/5 focal ratio, and the high focuser position results in a larger secondary mirror, which can reduce contrast. While some users have had positive experiences, particularly with modifications, a longer focal length Newtonian may offer fewer issues. Overall, the C-6N is a viable option for those willing to invest in improvements.

I have owned 2 other types of telescopes previously and i am looking to buy a Celestron C-6N reflector. Does anyone have any comments on this scope? (+'s or -'s)

If you are buying the whole scope/mount package:

then I would say that the mount is undersized and very unstable without replacing the aluminum legs with sturdy wooden legs. I have owned this mount (different scope on it) and it just doesn't do the job, especially with a 6" Newt. Mine got a fair bit better by adding wood legs from Naturewatch in Canada at $129, plus adjusting the entire EQ head so that the bearings were tight and all the slack taken out of the worm gear engagement.

As far as the optical tube itself, at F/5 you will have a good bit of "coma" with all but high power eyepieces. Also, the focuser is quite high which means that the secondary mirror is larger than should be necessary. This leads to loss of contrast (= less detail). The pluses are that the price is right for an EQ mounted 6" scope, especially if you are willing to do some "rehab" after you get it. A longer focal length Newtonian will cause fewer image and collimation problems.

I have an Orion 6EQ which, from what I understand, is the same OTA as the C6-N (by Synta). All the reviews I've read are pretty favorable as well. Google will provide you with plenty I am certain.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
