Featuring a 50mm aperture achromatic refractor, a 1.25" double helical focuser for precise adjustments, and a versatile dovetail mounting system, it simplifies star finding and autoguiding. Its robust anodized aluminum build and adjustable weight make it an essential, durable companion for serious astro-imagers seeking sharp, long-exposure images with minimal setup hassle. ## Description This small Guidingscope handles all the tasks of a "classic" Leitfernrohrs - but it is lighter and much easier to use! Previously used to long and large Leitfernrohre to find a guiding star. Eliminate the need to! The sensitivity of modern astro imagers is on your side. The Mini-Guidesope set as a viewfinder on your telescope.The 50mm Guide Scope is a complete and compact guide scope solution designed for use with nearly each autoguider and CCD camera in the market. The Guide Scope is ideal for guiding long-exposure astrophotographs with imaging telescopes up to 1500mm in focal length. Consisting of a 50mm aperture, 190mm focal length achromatic refractor guide scope, an adjustable dovetail guide scope bracket, an 1.25" aluminum parfocal ring, a dovetail mounting base, and an adapter plate, the 50mm Guide Scope makes it easy for any astro-imager to enjoy the precision of autoguiding in their images. All this pint-sized setup requires is a StarShoot AutoGuider or similar small-chip CCD autoguider and it’s ready for night, camera, action! The guide scope bracket fits into the standard dovetail finder scope base found on most telescopes. If your imaging scope doesn’t feature a dovetail base or has one already occupied by an oft-used finder, the dovetail base（not include）and attachment hardware lets you attach the 50mm Guide Scope to any optical tube. Alternatively, the included adapter plate can be used to attach the dovetail base and 50mm Guide Scope to any standard dovetail plate or side-by-side plate if preferred. Review: Very good as imaging scope for astrophotography to get a wide field. Review: I have the 70mm version and found this to be good quality optical instrument and a great guide scope - for folks who have a long FL main scope. There are other (and cheaper) FLs available. I bought a 0.5 FL reducer just in case – but haven’t used it, yet. Good dew shield, great worm focuser, well-built at 2.5 lbs and only about $160. To my surprise, for beginners who don’t want to spend too much money before they know they truly love Astrophotography and can master and afford it, it also makes for a decent primary scope (which is why I bought it – replace “beginner” with not-so-sure “returner”). Before you stop me and ask: “What about chromatic aberration? What about distortions around the edge of the field-of-view?” Well, the answer is: surprisingly, there isn’t all that much of that. This is actually a great beginner’s main scope if attached to a good (perhaps used, low $$ automated mound), a steady tripod, and a decent camera. Below, I will discuss three images I have recently taken. All are on the ZWO TC40 tripod with the ZWO AM5 automated mount using the ASIAIR PLUS mini-computer interface, and with a ZWO ASI 585MC camera. Note of caution: in that configuration, make sure the scope sits high up on the mount and does not easily run into the tripod. I am using a triple Vixen extender of which I have sawed off one offending member – but even then in that configuration the scope needs to be high on the Vixen receptacle to not run into the tripod. I live in the SF Bay area, so there is a lot of light pollution. Often I cannot even see Polaris with my bare eyes (and yes, I know it's a variable star :). All images were taken at a gain of 301; 200 images taken total, processed with DeepSkyStacker, Graxpert, and GIMP. All without a guide scope (through which I obviously took these images). Inexpensive SvBONY IR and UV cut-off filter to reduce dispersion. M53: Here I was mainly testing this guide scope’s optics. And since w/o guide scope, I used only 3s exposures to avoid star trails due to wind and mount tracking errors. DeepSkyStacker does not like short exposures, especially if there is a bright object in the frame (here: the core of the cluster). I needed to reduce the percentage of max light that is used for detecting stars for stacking: 10% is normal (about 3-4 stars, here; 5% not enough (about 5 stars, here); and 2% gives 7-10 stars, with only about 50% of 200 stacked images acceptable – which I picked; with drizzle set to zero for crisp dim stars. I think you will agree the image is great for this type and price of telescope. Leo Triplet: 90% of 200 exposure at 20s (no guiding, of course). Looks good to me, given the 70 mm aperture and the limited exposure time. M101: 148 of the 200 exposures where deemed good enough. Here you can see the problem when not taking “darks” at high contrast settings in GIMP: hot pixels and striations – but I did not care, for the purpose at hand. Edit: M101, another version: Same as before but now with a Celestron X-Cel LX 3x Barlow (!), and a ZWO ASI533MC Pro USB 3.0 Color camera. Using the 26 "best" out of 70 3m (180s) light exposures, gain 101, T = 0°C, 20 3m (180s) dark exposures, gain 101, T = 0C = 1h . FL should be 3x400 = 1,200mm but ASIAIR says it's 1,370mm. That happens with Barlows and varying back focus... and it is a problem: it means the effective magnification is not 3x, but 1370/400 = 3.425; or a relative light loss of 3.42^2 -- almost 12 instead of the nine I expected. So, bear that in mind - there wasn't enough light to use DSS to stack, but ASTAP worked fine. ## Features - Mini guide tube for quickly finding objects and guide stars that are designed for visuals and astrophotographs; worm focus: fast focus and prevents camera and eyepiece rotation; use as comfortable, large viewfinder with less time to find visual objects - 200mm focal length Design for astrophotography telescope up to 1500mm. Focal length up to 1500mm Wide field optics puts so potential guiding star; a locking screw that stays in place; Hex screws built into holes tighten two hex screws with hex key to lock - Adjustable weight for an astrophotography setup and can be conveniently stored in an accessory case between uses; dovetail guide mount installs on virtually any astrophotography telescope quickly and easily; - Sturdy metal housing made of black anodized aluminum that is solid and robust; milled and knurled ring allows for easy and precise fine focus adjustments; Comes with matching tube clamps and a Synta-style mounting plate to make mounting and installation easily - Integrated helical focus with brass compression ring and 2 thumb screws; 40mm focus range means 10mm focusing range with micro-focus helical focus and 30mm fixable with scaled traction tube which is made possible by extremely precise focus adjustment ## Technical Specifications | Specification | Value | |---------------|-------| | Package Dimensions L x W x H | 28.2 x 15.5 x 14.2 centimetres | | Package Weight | 0.59 Kilograms | | Product Dimensions L x W x H | 20.6 x 7.1 x 8.9 centimetres | | Item Weight | 590 g | | Brand | Astromania | | Colour | black | | Included components | 1X 50mm Guide Scope | | Objective Lens Diameter | 40 Millimetres | | Part number | SKU_AM_GS50 | | Size | 50mm Compact Deluxe Finder & Guidescope Kit | | Telescope Mount Description | Equatorial Mount or Altazimuth Mount | | Focus type | Manual Focus | | Guaranteed software updates until | unknown | ## Product Details - **Brand:** Astromania - **Model name:** 50mm Compact Deluxe - **Optical tube length:** 50 Millimetres - **Eye piece lens description:** Barlow - **Objective lens diameter:** 40 Millimetres - **Telescope mount description:** Equatorial Mount or Altazimuth Mount - **Focus type:** Manual Focus - **Power source:** Battery Powered - **Finderscope:** Reflex - **Item weight:** 590 g ## Images ![Astromania 50mm Compact Deluxe Finder & Guidescope Kit with 1.25" Double Helical Focuser - Guiding with The Mini-Guide Scope: So Astrophotography is Easier and Less Equipment - Image 1](https://m.media-amazon.com/images/I/713Z0l1JvfL._AC_SL1500_.jpg) ![Astromania 50mm Compact Deluxe Finder & Guidescope Kit with 1.25" Double Helical Focuser - Guiding with The Mini-Guide Scope: So Astrophotography is Easier and Less Equipment - Image 2](https://m.media-amazon.com/images/I/713Z0l1JvfL._AC_SX679_.jpg) ![Astromania 50mm Compact Deluxe Finder & Guidescope Kit with 1.25" Double Helical Focuser - Guiding with The Mini-Guide Scope: So Astrophotography is Easier and Less Equipment - Image 3](https://m.media-amazon.com/images/I/71HcGQjOWcL._AC_SX679_.jpg) ![Astromania 50mm Compact Deluxe Finder & Guidescope Kit with 1.25" Double Helical Focuser - Guiding with The Mini-Guide Scope: So Astrophotography is Easier and Less Equipment - Image 4](https://m.media-amazon.com/images/I/71aaAk7MNZL._AC_SX679_.jpg) ![Astromania 50mm Compact Deluxe Finder & Guidescope Kit with 1.25" Double Helical Focuser - Guiding with The Mini-Guide Scope: So Astrophotography is Easier and Less Equipment - Image 5](https://m.media-amazon.com/images/I/71p1+hkIXfL._AC_SX679_.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***E on 18 December 2017* Very good as imaging scope for astrophotography to get a wide field. ### ⭐⭐⭐⭐⭐ Review *by J***E on 19 May 2024* I have the 70mm version and found this to be good quality optical instrument and a great guide scope - for folks who have a long FL main scope.
