Marmot Posted February 18, 2022 Share Posted February 18, 2022 Whilst browsing the used market I recently came across the following EP: A Skywatcher UWA 58 degree 4mm. The most powerful EPs I have at the moment are a 6 and 5mm TMB clones. I was not particularly looking for a 4mm EP as I rarely use my 5 and 6mm, but I found the EP interesting for a few reasons: It seemed very similar to the TMB clones (with which I am very happy) and it was an unused EP being offered at less than half the price of a new one. Consequently I purchased the EP, probably more out of interest than actual need. The EP is indeed similar to the TMB clones that I already possess although it also has certain obvious differences: The EPs have the same 58deg FOV. The body of the EP is similar in shape and size although it utilises an undercut to secure it in the diagonal rather than a taper. The top of the EP has the same rotating, screw up and screw down housing to obtain a comfortable eye position, although the rubber eyecup is fixed whereas on the TMB clones it can be ‘flicked up’ or rolled back down. I also believe the rotation to be a little smoother on the Skywatcher. When the eyepiece was screwed all the way out/up there was a small amount of light grease on the exposed part of the barrel, something that I did not experience on the clones. The clones both came with a noticeable rattle which was easily resolved thanks to instructions supplied by ‘Nightspore’. The Skywatcher had the same rattle, although not quite as noticeable. I took the top of the EP apart in exactly the same way as the clones and found that the same retaining collar required fractionally tightening. So is the Skywatcher UWA actually another TMB clone or at least something very close? I would be interested to hear from anyone who can shed any light on this. As to its performance I can’t actually say due to poor weather. I have tried in daylight and on the moon in twilight, but due to poor conditions I can’t make a judgement on its Performance. Time will tell. 2 Quote Link to comment Share on other sites More sharing options...
