Anyone tried a oversized Lumicon finderscope?

[g__day]

I am thinking of getting one of these - for their superior light reach and the fact you can put a CCD or a standard 1.25" eye piece in them.

The 50mm is MSRP $US130

The Lumicon 50mm Super Finder Body is the 50mm Super Finder System without eyepiece and diagonal, for custom configuration. Switches from straight to right-angle in seconds. Sharp optics. Easy to use. Wide field-of-view.

Lumicon 50mm Super Finder Body Specifications

Objective Lens: Fully Multi-Coated 50mm Achromatic Lens
Focal length: 200mm
Weight: 1 lb.
Eyepiece/diagonal holder: 1.25"


The 80mm finderscope is USD $250

Lumicons new 80mm Super Finder Body is for those who already have a suitable 1.25" star-diagonal and eyepiece. It features the same high-quality components and construction as the Lumicon LS2020, without the correct-image diagonal, eyepiece or carrying-case. As always, your Lumicon Super Finder may be configured in either Straight Through or Right Angle mode, and switching between takes only a minute.

The Deluxe 80mm Super Finder Body is also popular as a digital guide-scope, and for wide-field astrophotography. It may be used with Digital Imagers and Web-cams in its Straight Through configuration, or with SLRs by removing the straight-through adapter (T-ring Adapter & T-ring required).

80mm Deluxe Super Finder Body Specifications:

Objective Lens: Fully Multi-Coated 82mm Achromatic Lens
Clear aperture: 79.8mm
Focal length: 300mm
Focal-Ratio: f/3.7
Focuser: 1.25" with 1" travel

Anyone tried these and have favourable or cautionary advice?

Thanks,

Got one. The 50mm version.

Mine is the straight version.

They are pretty basic but OK. No focusor on them , you simply adjust the eyepiece and clamp and test until you get a good enough focus. The eyepiece comes with an barrel extender that screws in.
Haven't tried it with a star-diagonal, don't think mine will reach focus that way with the existing crosshair eyepiece as there is insufficient back focus.

I'd rather have an 80mm finderscope , better for finding faint fuzzies. I knew someone who got a 80mm version and it was "super" , I would happily toss one of them in handluggage when travelling as grab and go scope if I didn't already have a pair of 20x80 Unitron binoculars which travel with me on holidays (great for checking out the beach from a headland or high sand dunes to spy on who is fishing and spotting where fish are feeding in the surf , and oh , also for stargazing . : :) :


You are probably looking at 40-50 USD postage to to get one over by USPS airmail.
