![]() I've read reviews that complain about a blurry field stop. I'm fortunate to have eyes that are astigmatism free, so I can remove my glasses to observe and correct my near sightedness by using the scopes focuser. I did not have older TV Plossl smoothie 32mm at that time, which is the best 32mm Plossl IMO.ĮR is clearly important to you. Here is my shootout between Meade, BCP and modern TV Plossl I would either pay a bit more and get older TV Plossl smoothie, or go with Meade 32mm. Have you tried the BCO 32mm?ģ2mm BCP is a nice EP, but for $65 I don't see the value there. Now thinking about getting the BCO 32mm to replace my Meade 32mm plossl that has a few thin chips in the coatings. Great info to know, but I will still not buy the BCO 18mm due to the short eye relief. I would bet that the BCO 18mm has a clearer image due to less glass and better contrast, but not a wow factor or even very noticeable difference.ĭirect comparison of the internal contrast in the Pleaiades nebulosity among these eyepieces: BCO 18, Panoptic 19mm, TV 20mm Plossl, Vixen NPL 20mm Plossl caused me to go "Wow!" over the BCO! YMMV of course. Also the SWA 20mm and SV 20mm have a 25 percent or greater field of view. ![]() The BCO 18mm has an eye relief of 14.7mm. The BCO 18mm is a good eyepiece, but not great in what I like in an eyepiece. I've kept 2 complete sets of the BCOs and the 3rd set is gifted to my grandson. This is the EP I would pick over $47 SWA 20mm or $45 SV 20mm any day (or night ). The GSO SVs aren't as good as the TV Panopics or the Takahashi LEs or the BCO and KK orthoscopics. It's been a while since I used the GSO SVs but last time I had them they weren't as bad as the ES100s that way (nor the Nagler 11mm T6 which I loathed for the same reason). That's why I finally got rid of the ES100s I had. In the SWA I had the stars looked cleaner and I picked a quite few galaxies with it, so the transmittance was not too bad. It could be QC issues, but that put me off trying more of SV line. To the point that it was somewhat annoying. In two SV EPs I had the brighter stars were always spikier than in other EPs of similar FL. But let's see if we can find some middle ground. ![]() Yes, I would not use them for doubles splitting now, but there was a time when I had just one EP set. I was surprised that you saw a difference in the SVs and SWAs with regard to scattered light though. Not interested in a CN style jihad either. I don't use my GSO SVs for situation when freedom from scatter is critical. SV and SWA are not the worst, but definitely not the best, somewhere in the middle. Well executed orthos have the least amount of light scatter and some badly executed EPs tons of it. You try couple of EPs on Jupiter or a tight double and difference in light scatter control become quite obvious. Not to start CN style war, but EP performance is always relative, and all EPs have light scatter, just different amount of it.
