Other problems with the "Black List" are that price should be taken into account. Some of the small low focal ratio (f5/f6) refractors could be ideal starter scopes given their portability and presumably attractive price. Satisfactory Planetary views could be obtained with the addition of a barlow and filter.
The list is quite useful as a guide but would be improved if the criteria were better explained , eg What does "corrector mean?
