I had to replace the custom mechanism for the telescope to a dovetail connector base to make it fit, but most accessories use that standard dovetail, so I would have needed to do so anyway. Once I've replaced the base with the dovetail one, this fit perfectly. The image through this finder is clear, it is easy to align (although, you'll have to align it as perfectly as you can on as far of an object as you can). I've used it a few times for finding planets and stars and have had no issue with viewing the night sky in terms of brightness, and finding what I wanted to focus on. I've seen a few reviews indicating it would be nice to have crosshairs to make it easier to see the centre, but on the scopes I've seen those crosshairs, they're on the side of the eyepiece, so it should be possible to add your own, it's also better to be able to choose crosshairs that are visible at night, because quite a few have crosshairs that are effectively invisible at night on the dark sky. Just to note, this is not an all-in-one, the eyepiece adapter is a standard one that fits 1.25" eyepieces, so make sure you have an eyepiece of your own. This has the upside of making the magnification of the scope modifiable as desired. Review: Crystal clear sharp pinpoint stars - Have not used it yet as a guide scope but did add a 25mm eyepiece and tested it out during the day and at night on the moon and a couple of stars just looking through it . Sharp crystal clear images!!! Pin point star images , sharp clear craters on the moon. Daylight viewing just as sharp. Helical focuser very smooth. Holder bracket has a nice tight grip on the body. My only dislike was one of the screws to hold the tube in place was missing the Teflon cushion pad but I can deal with that minor issue. I have no doubt this will be an excellent guide scope. This was my first ever guide scope and I'm glad I bought it to compliment my Astromania diagonal astrophotagraphy flip mirror . ## Features - Miniguide tube to fastly find object and guiding star that designed for visual and astrophotography; worm-focuser: fast focusing and prevent rotation of camera and eyepiece; use as comfortable and large viewfinder with less time to find object in visual - 200 mm focal length: design for astrophotography telescope up to 1500 mm focal length; wide field optics put so potential guide star; an locking thumbscrew holding in place; built in hex screws in holes that tighten two hex screws with hex wrench to lock - Adjustable aim dovany weight to an astrophotography setup and can conveniently be stashed in an accessory case between uses; dovetail guide scope bracket installs on virtually any astrophotography telescope quickly and easily; - Sturdy metal housing made of black anodized aluminum that solid and robust; milled and knurled ring allow easy and precise fine focus adjustments; come with matching pipe clamps and a Synta-style mounting plate to make assembly and installation easily - Built in worm focuser with brass compression ring and 2 thumbscrews; 40mm focusing range means 10mm focusing range with micro focusing helical focuser and 30mm fixable with scaled drawtube that is made possible by extremely precise focus adjustment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0156ICXMI | | Additional Features | Helical Focuser | | Best Sellers Rank | #16 in Telescope Finder Scopes | | Brand | Astromania | | Built-In Media | 1X 50mm Guide Scope | | Coating | Fully Multi-Coated | | Compatible Devices | Astronomical Telescopes | | Customer Reviews | 4.0 out of 5 stars 58 Reviews | | Eye Piece Lens Description | Kellner | | Field Of View | 13.68 degrees | | Finderscope | Reflex | | Focal Length Description | 190 millimeters | | Focus Type | Manual Focus | | Item Weight | 1.3 pounds | | Manufacturer | Astromania | | Manufacturer Part Number | SKU_AM_GS50 | | Model Name | 50mm Compact Deluxe | | Model Number | SKU_AM_GS50 | | Mount | Equatorial Mount or Altazimuth Mount | | Objective Lens Diameter | 40 millimeters | | Optical Tube Length | 50 millimeters | | Optical-Tube Length | 50 millimeters | | Power Source | Battery Powered | | Telescope Mount Description | Equatorial Mount or Altazimuth Mount | ## Product Details - **Brand:** Astromania - **Eye Piece Lens Description:** Kellner - **Finderscope:** Reflex - **Focus Type:** Manual Focus - **Item Weight:** 1.3 pounds - **Model Name:** 50mm Compact Deluxe - **Objective Lens Diameter:** 40 millimeters - **Optical Tube Length:** 50 millimeters - **Power Source:** Battery Powered - **Telescope Mount Description:** Equatorial Mount or Altazimuth Mount ## Images ![Astromania Guide Scope Finder Scope 50mm FMC Multi-Use with Helical Focuser | Compatible with 1.25" Telescope Eyepiece, Fit Auto Guiding Camera for Astrophotography, Metal Optical Telescope Accessories - Image 1](https://m.media-amazon.com/images/I/71jXkJxutQL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great finder scope *by D***L on April 28, 2025* This finder scope was exactly what I was looking for, it was a significant upgrade over the scope I had previously.

Sharp crystal clear images!!! Pin point star images , sharp clear craters on the moon. Daylight viewing just as sharp. Helical focuser very smooth. Holder bracket has a nice tight grip on the body.

This was my first ever guide scope and I'm glad I bought it to compliment my Astromania diagonal astrophotagraphy flip mirror . ### ⭐⭐⭐⭐ Great Finder with Two If's *by R***H on July 9, 2019* The 50mm Astromania finder features great optics and the potential ability to use the finder as a telephoto lens and use the finder in a straight through mode, 45 degree prism mode, or 90 degree prism mode. You can loosen a set screw to adjust the draw tube that holds the eyepiece or prism diagonal. You get a wide range of focus options, but it will not work for all prism/eyepiece combinations. Also, because of the sliding draw tube, you don't have an internal baffle. When sighting on an object near the moon, you will get a lot of annoying stray light. It's a well made accessory with the caveats mentioned. ## Frequently Bought Together - Astromania Guide Scope 50mm Compact Deluxe Finder Guide Scope Kit with Double Helical Focuser Compatible with 1.25 inch Eyepiece for Astronomical Telescope & Auto Guiding Cameras for Astrophotography - Astromania Universal Dovetail Base for Finder Scope - Ideal for Installation of Finder Scope, Green Laser Pointer Bracket - Astromania Dual Finder Scope Mount, Finderscope Mounting Bracket with Double Finder Mount Bracket - Adjustable Metal Aluminum Telescope Finder Bracket Installation of Red Dot Finderscope for Telescope --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/22350332-astromania-guide-scope-finder-scope-50mm-fmc-multi-use-helical](https://www.desertcart.is/products/22350332-astromania-guide-scope-finder-scope-50mm-fmc-multi-use-helical) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-24*
