Stellarvue F50M2 Deluxe 9X50 Finder Scope

Are you looking for one of the best finder scopes on the market? Then take a look at all the features the Stellarvue F50M2 Deluxe 9X50 Finder Scope has to offer. Let's begin with a generous 50mm aperture consisting of a fully multi-coated doublet object. At the other end is an image correct 90º erecting prism backed up by a 1 1/4" helical focuser with rubber grip, and a high quality fully coated eyepiece with large eye lens and cross-hair reticule. Both the eyepiece and the reticule may be focused and other conventional 1.25" eyepieces may be used. The finder will accommodate various standard 1 1/4" eyepieces. Most Naglers, Panoptics, Plossls and Kellners will come to focus. Certain eyepieces that are not parfocal with standard designs may not come to focus but this is the exception, not the rule. Unlike many finders that use inexpensive slide tube focusers or require screwing and unscrewing the objective to reach focus, the Stellarvue can be focused to accommodate different people thanks to its helical focuser. Merely turn the rubber grip to attain focus.

The eyepiece supplied with the Stellarvue F50M2 Deluxe 9X50 Finder Scope is a high quality, fully multi-coated, 23mm wide field eyepiece with 22mm of eye relief and a large eye lens. This eyepiece features a fine-focusing cross hair reticule, and accepts the Rigel PulseGuide Illuminator (sold separately under Accessories). In addition, several mounting ring systems are now available for the F50 finders. This allows many different brand telescopes to accommodate the Stellarvue F50M2 Deluxe 9X50 Finder Scope using standard dovetails. Our mounting rings use a dovetail rail with a safety stop. This rail slides into a dovetail base or a stalk for many different mounting combinations. Choose the proper mounting ring system from those listed in the Accessories, or add to your existing bracket for a 50mm finder!

A cure for zenith neck

I like the finderscope Meade includes on the LX200, but my neck and back disagree. Not only disagree, they finally rebelled a couple weeks ago while I was zeroing in on the Pleiades almost directly above my head.

So I ordered the Stellarvue F50-2 9x50mm Deluxe Finder scope from Oceanside Photo & Telescope (OPT because it has a diagonal with a rotating back, so you can easily look through the eyepiece, whether your telescope is aimed at objects near the horizon or straight up, simply by loosening the rotator locking screw to adjust the eyepiece to the angle you want. All that stops it from rotating a full 360 degrees is my optical tube.

Support staff at OPT said my current Meade mounting rings will work with the Stellarvue finder. They were right, saving that expense. That doesn't happen often.

Also, the Stellarvue finder comes with a 1.25 23mm eyepiece with reticle, but no illuminator. You have to buy the illuminator seperately... or not.

I have had a Meade 9mm eyepiece with illuminate reticle for a couple of years, but don't use it much due to its narrow true field of view in my telescope. I was happy to find that its illuminator screwed into the new Stellarvue reticle eyepiece and works perfectly.

So now I have two reticle eyepieces with different powers and fields of view that can share an illuminator. And, because the Stellarvue finder accepts other 1.25 eyepieces, I can use its 23mm reticle eyepiece on my telescope as well.

Here are my first impressions based on two nights of observations.

The Stellarvue finder scope appears to be solidly built. It looks good, feels good, and the moving parts work smoothly. The eyepiece has a focuser for the reticle crosshairs. The finder has a helical focusing ring which moves very smoothly.

There is a learning curve involved in using this finder, because it has so many moving parts grouped together in such a small area. My Meade finder scope has only one moving part, the focuser. The Stellarvue has six (once you add an illuminator. But you get the hang of it quickly.

Here's a rundown of those moving parts, starting where the scope ends and the diagonal begins: (1 Locking rotator screw to hold the diagonal at the angle you want for comfortable viewing (2 rotator (this is done by turning the diagonal (3 helical focuser (4 screw to lock the eyepiece in place (5 focuser for the reticle crosshairs, and (6 on/off brightness knob for the illuminator.

It does take an hour or so to get used to all of these and to find them easily in the dark without looking. That's particularly the case for the helical focuser and the reticle focuser, because they are so close together. But they are spaced almost an inch apart, and the knobs have a very different texture.

This is not a complaint. It is exactly because of all of these moving parts that the Stellarvue finder scope is so versatile. And more moving parts on the Stellarvue means fewer moving parts in my neck and back.

Excellent Finder
As one reviewer mentioned, you can see Jupiter and its moons through it. There are two focus adjustments, one for the cross-hairs and one for the eyepiece. There is a screw so you can rotate the diagonal to a comfortable position. The quality of all the components feels very high. It's pricey, but an extremely nice finder. Two thumbs up.

well made very impressed with the construction a true solid piece well packaged i have not mounted yet but have hand held and focused on a target with ease by hand the rotaing back will be a big blessing when mounted won't have to stren my neck are get on my knees when looking up can't wait until i add a rigel pulsguider to the kit a true asset to my 6 sct i'm sure that i will enjoy for many years to come and will be able to transfer to a new scope when i up grade my only concern is the double focusing while targeting my target star and that may be the olny draw but not a draw back and not sure about that until i mount and use other than that it is a great piece of gear as for as i can tell i'm very impressed well done stellarvue clear skies

Best finder ever!
I have had most all the finders out there,Orion,Antares,Celestron,Vixen but have not owned Taks or Lumicon yet and this finder is just perfect. It replaced a finder that came with my M603 mak which was like ones used on russian rifle scopes. Optics were good on the russian finder but needed a RA job. This is so good its almost like a second scope and I think maybe the 60mm would be just like that. Looking ar jupiter you see the planet and its moons, no comet tails, star feilds are excellent and the focusing is perfect. At $120 this is one excellent finder and you can use your other ep's on it to. The fit and finish is first rate,great stuff!!!
