Celestron PowerSeeker 127EQ Renovation

"We’ve had it for months, couldn’t ever say anything through it."
"Might as well have thrown the money out the window."
"You'll never be able to collimate the primary mirror even if you are a magician..."
What might be greater than a magician? Ah, I know, a wizard...

I had read all of the reviews on Amazon.com, but only after having received the kit...
My own arrived mis-collimated; Polaris...
But after its renovation, I saw Jupiter's Great Red Spot, and for the very first time in my life; with any of my telescopes. I can also attest that the bundled 4mm eyepiece, a symmetrical-Ramsden I think, is a treasure in its own right...
...the 20mm erect-image, not so much; nor the barlow. To make use of the finder-scope, its yoke should be shimmed...
...not too tightly, nor too loosely, just right rather. It will then align nigh perfectly. True, it's only a 5x24, but not bad.
The kit also came with aCG -2(EQ -1) equatorial mount...
I had renovated that, too, with thin bronze-sheet and needle-thrust bearings, but for my smaller telescopes. The mount will never be used with this 127mm telescope, as it's much too small to support it properly. This thread, however, deals with the telescope itself, theOTA only...
I got this kit on purpose, rather than unwittingly, for theOTA mainly, and the mount for those smaller. If this is to be your first, or your only telescope, get or have a separate, supportive mount for it; no ifs, ands, or buts.
Regrettably, this kit is most attractive to those first starting out. It's got the short tube -- easy to handle, store and travel with -- but most importantly, it's got that low, low price -- perfect all round, no?
Truth be told, I cannot and will not recommend nor suggest this kit for those first starting out, not ever. The telescope is a veritable Chinese finger-puzzle, and one that I have successfully unravelled. It is an economical alternative to a Celestron C5 Schmidt-Cassegrain. It is also, albeit incognito, a 127mmf/ 4 Newtonian, and all that that entails.
