I recently discovered I needed new binoculars. My Celestron Nature 10x50, which I have had for appx 9 years, performed very well and in fact did an excellent job for astronomy purposes. Their cost was reasonable (under $100), they were nitrogen purged, had BK4 lens, and were fully MC. However with use there were some issues: Focussing was not smooth and often threw the views out of culminations, and they were not durable. One minor bump and there was a problem. However, until recently they served me well. Then, I noticed some problems with the views that I found were not economically repairable. . For my new binocs, preferable 10 x 50, I would have an limit of $100 US. So, I spent a week comparing various binocs by Coatings, BK, durability, until I narrowed brands to just a few. I like a Bushnell Legacy 10 x 5o for $96, a Nikon for $99, a Cannon for $99 a Simmons Pro for $68, and several Celestrons. And there were more. All had similar specs. It was difficult to find glaring differences. So, I checked in-depended reviews. Finally I went with Orion’ Scienex 10 x 50. I went with them because in almost all reviews and comments to the good they are mentioned. Not always on top, but always mentioned as good astronomy binocs. And that has been ongoing for years. There might be better, but I’m pretty sure these are a safe bet. So any rate they arrive next Wednesday and I’ll soon see. Later Lenny.
