Stellarvue F50M2 - 9 x 50 Deluxe Finder with Reticle Eyepiece - Matte Black

The F50M2 Deluxe 9X50 Finder Scope  with 50 mm (1.97-Inches)  Aperture by Stellarvue:


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 50 mm (1.97-inches) aperture consisting of a fully multi-coated doublet object. At the other end is an image correct 90-degree erecting prism backed up by a 1.25-inch helical focuser with rubber grip, and a high quality fully coated eyepiece with large eye lens and cross-hair reticle. Both the eyepiece and the reticle may be focused and other conventional 1.25-inch eyepieces may be used. The finder will accommodate various standard 1.25-inch 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, 23 mm wide field eyepiece with 22 mm of eye relief and a large eye lens. This eyepiece features a fine-focusing cross hair reticle, 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 50 mm finder!

Stellarvue F50M2 Deluxe 9X50 Finder Scope Features:

  • Rubber-grip helical focusing ring.
  • Accepts alternative 1.25-inch eyepieces.
  • Compatible with a huge array of mounts.
  • Included 23 mm eyepiece has outstanding eye relief!

Ask a Question
  • I have a spare Orion bracket for a 9X50 finder. Will it work with the Stellarvue finder?

    Probably not, as the StellarVue finderscopes are around 56mm in diameter- wider than the Orion finders - so it will have an issue in the Orion bracket.

  • I read a review on CN which said that Barlow's will not work o this finder? Is this true? What about Powermate's?

    I have used a barlow with a autoguider camera to turn this finder into a guidescope, but I was never able to get an eyepiece into focus with the barlow. I doubt that a Powermate would work, but it is possible with a Plossl type eyepiece as Powermates are

  • What bracket/rings are needed to bolt this to an Orion XT10i?

    Tom, The SV-R50SCT will work for you. It has a vixen style base which is designed for a Schmidt Cassegrain Telescope but you can drill holes to fit onto the tube. You could also go to a Telrad which has adhesive strips.

  • Can you use this for Celestron 9.25" Schmidt-Cassegrain OTA?

    Marcelo, Yes, that Stellarvue finder will work on the Celestron 9.25 OTA. You just need the Stellarvue SV-R50SCT bracket and the Vixen style dovetail base. If you don't have one, then the OS-VFS will fit. A simpler alternative would be the Celestron Ri

  • Can you use this for a guide camera setup?

    It will work without accessories if you are using a QHY5 variant, SX-Lodestar/X2/Superstar, or SBIG STi , but other guide cameras cannot be moved inward far enough. You will need to add a barlow of some sort to reach infinity focus with other models of au

  • Question 1. Does the image shift when the diagonal is rotated.? Question 2 Can you lock the focuser ?

    1. Yes, the finder will need to be re-aligned whenever the diagonal is rotated. 2. Not at this time, although StellarVue is working on a modification.
