Thanks to the generosity of one of our members (Dave221), I recently came into possession of a Vixen SkyScope D 60L. This scope a typical 60mm beginner’s refractor and its type and ilk have been the subject of much criticism (see "Gift of a hobby killer" ) https://www.iceinspace.com.au/forum/showthread.php?t=207831 in astronomy forums.
So after a few repairs I decided to test it out.
The tripod extends to a good height and makes the eyepiece reasonably accessible. The finder I lined up by day, and shows only the bright stars in the field which I estimate to be around 7 degrees wide. Once near the centre of the crosshairs, the object was then in the field of the 12mm eyepiece. I only used the 12mm .965” eyepiece which yielded 67x.
The mount is fitted with slow motion controls on both axis that worked very well.
First object was Jupiter, high in the north. Three moons easily visible, the fourth was no doubt transiting and I could not detect it. Four bands were easily seen and good contrast against the pale yellow of the disc. Focusing was not easy as every time I touched the focuser, the image shook. But at F13.3, there is plenty of depth of focus so the image was sharp and clear.
Next up a couple of double stars. Rigel is often thought difficult, but I have seen its fainter companion many times in a quality 60mm. And to my surprise I could see it also in this scope. Then pointed the scope at Achernar to view a nearby double P Eridani – sure enough the snake eyes pair was clear and split.
Finally onto M42, and despite the full moon rising . a good bit of the nebula was easily seen and to my surprise I could see the four stars of the trapezium – theta Orion!
These were just a few of the observations I made. A determined young beginner could easily do the same or better – it is only my years of observing experience that keeps me in the game.
In summary, I feel this type of scope has received too much bad press over the years. Sure my example was a “quality” 60mm – probably much better than the $60 to $100 items that appear on ebay, but the observations showed that with a bit of perseverance a 60mm can show many objects and hopefully lead to further interest in seeing more with a better instrument.
This scope is bound for a family with a young daughter - I am hoping it sparks that interest.
