Delite selection
I own a Tele Vue 102 refractor and and have a small selection of eyepieces and try to keep it that way. My scope is 8.6fl and I currently use a selection of Tele Vue Delites: 5, 7, 9 and 13mm with a Tele Vue 32mm Plossl at the other end. This gives me x27, x67, x97, x125 and x176mm. I like eyepieces with plenty of eye relief and use an eye guard extender with the plossl, which is very comfortable.
Can anyone see any obvious errors in my thinking.
Mount: Gibraltar HD4
Eyepieces: Nagler Zoom; Delite 7mm, 9mm, 13mm; Plossl 32mm
Filter: Nebustar UHC type 2, er… that’s it!

Re: Delite selection
Yeah the 18.2 mm are nice, I had one once, it was very good. As it happens I sold it to fund the 13mm, which is another excellent ep. There is however only a x40 jump between the 32mm and the 13mm. It’s not as big a leap as one might expect, perhaps I should think about that again

Re: Delite selection
I would recommend a APM/TMB 1.8x or a Vernonscope Dakin 2.4x.
With the offset power you will not double focal lengths.
Of course this all depends on what objects you enjoy viewing.

I have had 4 Barlows I reckon. I even bought one before Christmas and sold it in the New Year. I can never keep them, they always seem a good idea at the time and the views have always been solid. I just don’t like using them. I always try to keep my gear down to a minimum and avoid any kind of messing around or any jiggery poker involving electrical equipment. Mad thing is buying another still seems like a good idea.

Re: Delite selection
The big jump here is between 125x and 176x. When using high powers in a 4", you run up against seeing and field size considerations.Caldwell 14 wrote: ↑Thu Apr 11, 2024 4:10 pm Hello folks

I think 120-150-180 makes a great progression, and you have one already close to the 120x and 180x, so I'd pick one around 150x.
With a 880mm focal length, that would be a 6mm eyepiece. The question is, which 6mm?
You favor long eye reliefs, so these would be good options:
brand model FL AFoV e.r.
Tele Vue Optics Delos 6.0 72 20.0
Founder Optics Marvel 6.0 80 20.0
Long Perng 80° Series LER 6.0 80 20.0
Orion LHD 6.0 80 20.0
Stella Lyra (FLO) 80° LER UWA 6.0 80 20.0
All four of the last 4 are the same eyepiece with a different label on the outside.
All 5 of them are made in Taiwan. The ones made by Long Perng are Delite price or less.
Currently using a 12.5" dob and a 4" apo refractor

Re: Delite selection
Since all my other gear is Tele Vue I might as well stick with what I know and that probably makes a 6mm Delos.
I used to have a 6 mm Radian in the past that used to produce terrible ghosting. Apparently the light was bouncing back off my retina back into the eyepiece. Something to do with the eyepiece polish and the shape of my retina, apparently it is a thing in some people. It was a type 1 Radian btw.

Re: Delite selection
Very nice views and since you have experience using Plossl already this should not be a problem since the AFOV stays approximately 50°

Re: Delite selection
In all cases the TV 3-6 Nagler zoom is my go-to for high-power viewing. Image quality is excellent, it maintains its focus as you change power, and it enables you to find the 'sweet spot" for whatever the atmospheric conditions are. I highly recommend it.
I have run it at 3mm, or 272x with the Tak, on different manual push-to mounts, and apart from the fact that the Earth moves very quickly at that power I have never had problems keeping my target in the field.
All the best,
Dean
Binos: Steiner Wildlife XP 10x26, Swarovski 8x30 Habicht, Zeiss SFL 8x40, Vanguard Endeavour 10.5x45, Fuji FMTR-SX 10x50, Tak 22x60, Orion Resolux 15x70
Eyepieces: way too many (is that possible?), but I do like my TV 32mm plossl, 13mm Nagler T6, 27mm Panoptic and 3-6mm Nagler zoom, plus Fujiyama 18mm and 25mm orthos and Tak 7.5mm LE
