Simple to set up and very easy to use, makes star hopping a breeze, most useful accessory I've bought in some time. As always excellent service from FLO.

Having tried simple cardboard models of both the Telrad and Rigel finders I found that the smaller footprint of the upright Rigel fitted this scope much better (but I did need to move the finderscope base away from the focuser to make room).
It is high enough off the body of the scope with the supplied mount to allow for comfortable viewing.
It was easy to install (the sticky pads hold very well) and simple to adjust to centre the image.
It is very light so hasn't changed the balance of the scope much.
In action it works really well. It will centre a star in all but the highest magnification eyepieces and the circles really help when star-hopping.
The ability to turn the brightness down makes centering dimmer targets much easier. (I haven't used the blinking option much yet.)

Overall this has been a really worthwhile addition to the scope.
It has made finding visible targets very fast, accurate and easy (and has also encouraged me to develop my star-hopping skills for less visible targets). Don't hesitate, get one!

Have just purchased another one of these, as my first one has packed up, after many years of good service I might add. Good old FLO. Needed to get a replacement quickly. Could not imagine an evening session without one.
I have bolted the baseplate to a small 2" long dovetail bar, so I can swap between scopes and mount using the finder scope bracket because with one of these you don't need a finder scope.

Needed to upgrade the finderscope on my 4.5" newt. The one that came with it wasn't very good quality at all. After some deliberation I've decided to go for a twin set up of this rigel and a 9x50 RACI finder. As pennies are tight will be buying them as and when I can afford. Thought I'd give the rigel a go 1st. Super easy to fit and align and works perfectly. Definitely aids with star hopping with the 0.5 and 2 degree circles. This was my first time buying from FLO but certainly won't be the last as I've already been eyeing up the RACI lol. My only complaint would be that FLO when they packed up the item seemed to have packed a few too many clouds as it has been about 2 weeks since it arrived and tonight is the first night I've had clear skies. Other than that really pleased with my purchase.

I had a basic straight through 6x30 finder which was frustrating to use on it's own with my long refractor. Getting the correct initial star lined up for star-hopping could be difficult, but the Rigel Quikfinder has solved that problem. You have to be looking through it at the correct angle to see the reticle, but once aligned and you've got the hang of the viewing angle it's so easy to get that initial star found.

I've mounted one of these on my 20x80 binoculars to help me navigate the night sky. Before using this, it was a bit of a hit and miss approach, what with the field of view provided by the binoculars. That FOV is fantastic when actually looking at what you want to see, but can make it a bit tricky finding that target. The Rigel has solved all of that for me. I can now aim my bins at my target using the Rigel and it's bang on centre in the binoculars. The whole process takes mere seconds. It removes most of the frustration and provides more observing time, so a win-win.

I had some fun trying to mount these on the binoculars. They are designed for telescopes after all. But after some experimenting, I manage to keep the base plate nice and stable with the use of a couple of long cable ties. This keeps the base stable enough for me to be able to detach the main unit so I can store the binoculars in their case to keep them in good order without requiring realignment of the Rigel once re-mounted.

I do often forget to switch the Rigel off, so not sure how long the battery will last, but that's an issue with my memory rather than the device itself.

I also ordered some extra base plates so I can easily move this between my binoculars and telescope as and when needed.

I'm happy to recommend these to anyone who wants to have an easier time of pointing their observing tools in the right direction.

The finder presents you with a bulls eye arrangement, very dim so cannot be aligned during daylight however at night can be adjusted to provide the required level of brightness. As the base is held on by sticky pads, I was concerned that by removing the finder from the base, this would loosen the base, proves not to be the case. I like it.

Luckily I haven't had any such issues though. It's a nice finder, and allows sufficient dimming to be able to track to the faintest target. It is easy to mount with the included sticky tabs

I was at the end of my wits with the Meade RDF fitted on a 90mm StarNavigator. It only has 2 brightness settings and alignment to anything but exceptionally bright was challenging! It seemed the Manufacturer left me with limited options to change it. However, thanks to a few enquiries I managed to find an alternate solution and this is it. The adjustable Telrad finder makes finding objects a breeze and is so much better than what was fitted. The box comes with everything you need to get started with exception of the CR2032 battery, which to be fair is fairly common and can be bought almost anywhere. The included double sided adhesive pads seem to do the job once you have fixed it to the OTA and no problems since. I would agree that you will need to do alignment when conditions are pretty much dark, otherwise you probably wont see it. I would suggest one of the bright stars (I used Arcturus) and once this was completed all was good. Id like to thank the FLO team for their recommendations on this item and for a speedy delivery. Would definitely purchase from them again.

Excellent upgrade for the RDF on a Heritage 130p. Highly recommended.
