My experience with Unitron is limited to that of my 114. The optics are nothing shy of fantastic, and on a good night, will allow insanely high levels of magnification without any hint of image breakdown. This is not to say that it will outperform the theoretical limits of a 60mm objective, but I have no doubt it pushes those limits with ease.
When Jupiter and Saturn made their close approach, I set up my Questar to enjoy the show. The Pastor from the church down the street saw me and asked if I would let a his congregation take a look. I was a bit paranoid about being around the twenty or so people due to the raging pandemic, so I told him to wait a couple of minutes while I ran back inside the house. I grabbed the 114 since I knew it was so easy to use and should give him no problems. Also, the image of the two planets together would easily be displayed in all their glory. When I came back out with the Unitron, I told him to have fun and bring it back when they were done. They were all thrilled with the show (and I didn't catch covid).
Awhile back, my wife's sister mentioned that she would like to purchase a telescope. My wife took this as an opportunity to free up some space, so I was on the hook to come up with something. My first thought was my C8 or my C90 Astro, but I decided both would most-likely end up being more work than she's willing to put into the hobby at this time, so I decided the Unitron would be perfect. Ease of use, and she could leave it setup for use on a moment's notice.
So, do I need a Unitron? Probably not. Then again, I have other refractors that perform at least as well, so I'm sure I won't miss it too much when it's gone. Then again, if it were my only scope, I'm sure I would do my best to wear it out.
