Message: <blockquote data-quote="FrankD" data-source="post: 1497624" data-attributes="member: 18544">FWIW, I received the 20x50 Yukon Firefall today.It came in a shrink-wrapped package.Positives:It is very small and very light.It is very inexpensive.The image at 20x is very wide....170-some feet by the listed specs.Negatives:Eye relief is short....and if I thought the 12-36x50 wasn't as sharp as I would like then the 20x50 definitely is not as well. In fact after comparing the 12-36 to the fixed 20x I would most certainly say the 12-36 is noticeably sharper at all magnifications. It also appears to be marginally brighter at an approximate 20x setting. Fit and finish seem about equal with the focusing tension and overall feel going to the 12-36x.I also received the 15-45x65 Promaster Elite ELX ED spotting scope as well. This is an interesting scope in that it does accept the standard 1.25 inch astro eyepieces just like the Pentax. However, there isn't a locking collar with the Promaster. The eyepieces just slide into the scope body with no way to lock them in place (maybe some type of external adaptor?). This wouldn't be an issue if you are just keeping the scope stationary but if you plan to pick up and move it around then you are going to have problems.Color fringing seems well enough controlled though there seems to be more field curvature with both the provided 15-45x eyepiece and the Pentax XW 20. The latter I find interesting as I was under the impression that the eyepiece pretty much determined this type of image characteristic....?More to follow.</blockquote>
