I am so happy with this Omegon Red Dot Finder and wish I had had some more information before I tried to set it up and use it. It's very precise and everything is included in the envelope that one needs to get going. In fact there was even a spare battery and a bag of jelly babies for me to munch on while trying to figure it out.
Firstly, ignore the flimsy bit of paper that is included. It goes on about guns (which I abhor) and I couldn't even read it without getting annoyed! So, download the pdf instruction file from the Omegon web site. The instructions are not perfect but get a B rating from me. The rest I worked out for myself.
Second, learn how to install properly in a camera hotshoe. There are two Allen keys provided - the small one is for tightening the hotshoe adapter into the camera hotshoe; and the large one is for tightening the rail base. Both of these must be done in sequence to ensure a really tight and firm placement. The unit is rock-solid if attached correctly.
Third, wait until daylight to test and adjust the unit. I tried at night and had nothing but grief and was on the point of sending it back! You will need to remove the screw caps from the two adjusters and need a coin or small screw-driver to turn the screws (lots of fiddly things to lose in the dark). I haven't had it long enough to know but assume once set up on a camera with a specific lens it will maintain the adjustment until the lens changes and/or put it on a different camera. Then set the camera up on a tripod and pick a small distant stationary object. Using the tripod adjustment place the centre of the camera focussing screen exactly on top of the selected object. Use the two fine adjustment screws to also get the green (or red) dot exactly on top of the object. Now, you may remove the camera from the tripod and just use the red do to find your subject - magic.
Of course it makes your rig much heavier but think it would work equally well with a gimbal head and large lenses. I can't wait to try and pinpoint some astro with it but need to wait for clear skies.
So, thank you to astroshop.eu for the great service - it arrived here in Scotland in a few days. I just wish I had had better instructions.
