Indeed! I actually probably started with the WORST telescope - a 40mm reflector that had a PLASTIC SQUARE secondary that had some reflective tape for a mirror on it. But like you, that showed me the moons of Jupiter, the rings of Saturn, many craters on the Moon and it ignited a passion for astronomy in me that burns 40 years later.
Rick, I had the Skilcraft Satellite version of this 40mm mutant Newtonian (mu-tonian?). I didn't even KNOW there was a 100x version with a rack-&-pinion focuser! Yours was obviously a rare "premium-grade" version. Mine (late '70s) had a twist/push/pull "focuser" lined with green felt. Secondary, if I'm recalling correctly, was a second-surface rectangular glass mirror. I've seen another Satellite with a FIRST-surface rectangular secondary. -And yours had a plastic silver-tape surfaced secondary?! Wow. The mind wobbles. Mine had a "steel" tripod with a ball-&-socket "head." After the wee steel pin holding the head to the tripod finally gave up, I built an equatorial fork-on-pedestal mount for it, using scrap 2x4s, 2x2s, and box nails. With the 40x & 80x eyepieces (one Ramsden, one Huygens), I managed ultra-low-contrast views of the SEB on Jupiter (almost imaginary, it was so subtle), a single-ringed Saturn, the core of M42, and a barely-there wisp of the Great Cluster. Luna, however, was much "easier" and provided countless kicks in the pants.
I was lucky to have spent MANY hours on the roof of our house, with a pair of Bell & Howell 8x40s, for a few years prior to receiving the Skilcraft (as a birthday gift), and likely just as many hours in bed or a chair, devouring the original Petersen's Field Guide by Menzel. When I got the tiny long-focus Newt, I knew it wouldn't rival an Edmund 6-incher, or a Celestron 8, but I was determined to squeeze as much satisfaction out of the mu-tonian as I possibly could.
And I did.
Hobby killer? Heck no. A kid's first (and last) night with a poor telescope can't kill what isn't yet alive. "Hobbies" are borne of knowledge, practice, and experience. The worst things a poor scope can do is provide a learning experience and perhaps trigger some regret at spending some money. If there's more "damage," perhaps it's not quite the scope's fault.
I still have a Skilcraft Satellite - a strictly nostalgic purchase many years after my first one was dissected (I just HAD to see that primary up close!) and discarded.
My views through my Jason 307 Explorer, on the other hand, are quite nice (even when stopped down to 40mm). That's another story, though.
Cheers and good seeing.
