IMHO,blackouts are not an issue at all if the adjustable eyecup is set properly.

Yep, The Antares adapters work great! Markus (Scanning4Comets) pointed them out in one of his posts last year, and I had to pick up a few. I currently go 48,27,10,4.5 for my 2" "wide field" set

Nice James! Another cool thing with those adapters is that you can screw the bottom of the 2" GSO barlow element right onto it !!!

Per Tele Vue, the way to do this is:

1. Put eyeguard in full up position
2. View through eyepiece (all FOV will NOT be visible)
3. Slowly lower eyeguard until you can just see the entire AFOV
4. Lock eyeguard in that position

I just acquired my first Radian eyepiece, a 4mm. Terrible blackouts unless you position your eye correctly. Worse than the old Orion Epic ED-2's! Now that's saying something. But it's not a real problem to set the Instadjust for the eyepiece. Sounds similar to what's on the Delos. No big deal. Just takes a little experience, a little trial and error. I'm not sure if I like that gizmo or think it's really necessary, but it's not a biggie.

Of course Radians and Delos are TeleVue , so I suppose they are not criticized for blackouts to the extreme extent that Orion Epics were ... even though, in my experience the blackouts in the Radians are much worse than they were in the Epics.

I have a few of the twist-lock adapters, also, Antares as well as other brands, and I use them often. But I do not have them permanently connected to my 1.25" eyepieces.

There are several negative aspects to having all your 1.25" eyepieces permanently in adapters. First and maybe foremost for me, is that they will take up more space in the eyepiece case. Also, if you have an eyepiece rack on your mount which has holes for 1.25" and 2" eyepieces, the 1.25" holes will be wasted. Another problem is that you will have to take the adapter off to fit the 1.25" eyepieces in a filter wheel or binoviewer.

For me, these inconveniences do not make up for the small amount of time needed to take a 1.25"-2" adapter on and off an eyepiece. Personally, in my experience, there would be no real advantage in transforming all my 1.25" eyepieces into ersatz 2" eyepieces. I don't get that. YMMV To each their own!

But Mike, when you don't have any of those constraints it works pretty well! LOL!

Seriously, I wouldn't do it otherwise, but the ethos SX's have the 1.25 adapters on them, so I would be switching from 2"-1.25"-2" more often. If I took them off the SX's, them there would be two of those adapters, plus the adapters from the diagonal and telescope all kicking around. For me, it's less loose parts the dark. :-)

My dark site, where these are going to get used the most, is in a small railed platform on top of my parents house near the seashore. If I drop something, it bounces down the roof over the gutter, usually, and into the landscaping. Losing an ethos SX adapter sounds expensive to replace if I can't find it.

Negative aspects? There are ZERO. They don't take up space at all....Eyepiece racks are useless in the winter or when it's really cold out because the eyepieces just fog up after exposure, this is why mine is removable and has all 2" holes for when it is a bit warmer. Not everybody has a filter wheel or binoviewer, so that's a moot point. There is a HUGE advantage to having all of your eyepieces in 2" mode as opposed to fiddling in the dark with your adapters.....with them all on there, they stay on there and just go into the 2" part of your focuser, etc.

Why mess with adapters when you can just leave them all on and use them that way.

Happy New years!
