Small, red dot finder for daylight?


Recommended Posts

Hi,

I have never seen a red dot finder in the flesh. Let alone owned one.
So you may safely assume zero knowledge.
I need some quick advice from direct, hands-on experience.

I thought I'd get one to speed my aim without fitting a proper finder
Really don't want to fit one one right now.
[It means major dismantling, tailpiece and baffle removal, drilling main tubes and re-balancing.]

Do these things work well in bright sunlight? This is important to me.

How small do they go? This is also important to me.

Flash shoe fitting on a 4/3 mirrorless DSLR small?

How accurate are they? Moon's width or less?

Does quality vary much between makes and/or price?

Any strong recommendations from direct personal experience in the "bijou" category?

Grateful for any advice so I can put in an order ASAP.

Thanks.  :thumbsup:

I've always used red dot finders, on my dobs I've had the telrad and on the refractors the Baader Sky surfer V. They now sell a night and day variety but even the night time one still works in the day but the smallest red dot is very hard to see in the daytime.

The smallest setting is pretty small I could not tell you how small but it's a very small pin prick of light about the same width as a small star. As for quality you pay more you get better quality, I've always used Baader as the quality is excellent.

I only have two unbranded versions. One is just a plain red dot and the other I can change between a dot and a cross by turning a wheel.

Both can vary the brightness

In terms of visibility I always calibrate the finders in daylight as a first setup using the top of a tree which is about a kilometre away. I put a cross hair eyepiece in the telescope and position the cross hairs on the tree top. Using the left/right adjusters on the red dot finder I then position the dot onto the same part of the tree.

Further positioning calibration can be done at night on a star if required.

Depending on the quality of the shoe mount the repeatability from removal to reinstall is quite good

Thanks for your helpful advice. :thumbsup:

I was referring to the small size of the finder bodywork rather than the dot.

A green spot or cross sounded like a much better idea for daylight use.
Strapped to a spotting scope for digiscoping on featureless lakes.
Or homing in on planets in my 6" refractor once I have fitted a camera and/or a Barlow and completely lost focus. :rolleyes2:

More homework definitely required!

Thanks again.

I forgot to mention earlier that I made this handy 'bracket'...

from a spare TeleVue 'Qwik Point' mounting block; two 15mm pipe clips
and two short 5mm machine screws & two 'nyloc' nuts and clips to the
centre horizontal bar for use with my 20x80 binoculars and RDF.

I bought a cheap red dot finder off ebay for a small scope.  It is compact and can be made very bright for daytime usage.  After all, they started out as gun sights.  Make sure to get the correct foot/shoe for your mounting needs.

There's a vendor on CN Classifieds selling 3D printed camera flash shoe to Vixen finder mount adapters:
