## Overview

The Astromania 50mm Compact Deluxe Finder & Guidescope Kit is a meticulously engineered guiding solution featuring a 50mm aperture, 190mm focal length achromatic refractor, and a 1.25" double helical focuser that eliminates slop for ultra-precise focusing. Its adjustable dovetail mount and robust anodized aluminum build ensure compatibility and durability across most astrophotography telescopes up to 1500mm focal length. Designed to streamline star finding and autoguiding, this compact kit enhances long-exposure imaging with wide-field optics and secure locking mechanisms, making it a must-have for serious astro-imagers seeking reliable, professional-grade performance.

## 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: Edited review.....after some time witht his scope I decided to add some more info....see the additions at the bottom. First....the reviews here are for a combination of all models....50mm, 60mm, 70mm. Mine is the 70mm. I already have a 50mm home made autoguide scope that works fantastic...but needed a longer focal length scope to maintain the right ratio for one of my longer focal length scopes. The most important thing for an autoguide scope is it must have absolutely 0 slop....if it has even the slightest amount of slop it will never give good results. I was pleased that they addressed this issue and have a rock solid setup. While it has a long coarse draw tube, that would be problematic if it couldn't be locked down....there are three screws to lock it in. place...one thumb screw and two set screws. I never liked using Allen screw wrenches in the dark so replaced those two set screws with thumb screws. The double heclical focuser has no slop and works smoothly. Once focuse it has a thumb screw brake to keep the focuser from moving. Finally 1 1/4" focuser has a brass compression ring but goes one extra step by including two thumb screws to really lock the camera down. The scope rings have nice larger thumb screws for adjustment and have plastic tip inserts so you won't scratch the scope barrel. In the picture at desertcart it looked like the lens was very close to the front of the scope and I was concered I might have to make s dew shield. Turns out it has a decent dew shield that slides out to about 1 1/2" from the lens. That is just OK....my future project it to make a much longer one to cut down the chance of dewing. I have much longer dew shields on my main 6" APO refractor and also my old 50mm guider scope and surprisingly have NEVER had to deal with dew with either scope. But if necessary I do have dew heaters. Overall the scope looks very solid and is well engineered and at a good price. The only possible CON is that it is a much larger/heavier scope than the 50mm and 60mm versions. If you have a mount that is at its limit weight wise this may be the thing that puts it over the top and you may not get good results with your overtaxed mount. I have a Astro Physics 1100 so no problem. The old maxim that a guide scope should be around 1/3 of the focal length of the main scope is based on visual guideing. With todays guiding cameras the recommendation is to keep the ratio to a max of about 1/6th of the main scope focal length to as much as 1/10th of the ratio depending on the pixel size of your guide camera. The 70mm scope has a 400mm focal length so that should easily guide up to a 2400mm focal length with an average camera and as much as 4000 mm with a small pixel sized camera....but that would be pushing it. Todays software and cameras are so good that once setup you should have no problem getting rock solid guiding as long as you have a good mount. For short focal length refractors though this 70mm - 400mm focal length scope may be overkill....one of the cheaper, lighter guide scopes (50 or 60mm) will work just fine as they have around 165mm to 240mm focal length. ================================ Additional input from my original review.....I continue to be very impressed with this scope as a a guiding scope....so much so I bought the 60mm version for use with my travel scope and mount which is a ZWO AM5 mount with 80mm APO refractor. The 70mm worked fine with that setup but i was overkill....the guide scope was narely as lartge a the main scope ;-) Since Ilready had a 50mm home made guide scope I decided to go with the 60mm that has ad 240mm focal length. I definitely like the new scope as much as the 70mm and construction is idential on both. I used the larger 7omm version with my AP 1100 mount supporting either a 6" APO refractor or a 11" Celestron SCT HD. Guiding using Maxim DL was flawless and I never had any problem finding stars to guide on anywhere I aimed my telescope. I also removed the two hex screws that the stock setup had and replaced them with thumb screws identical to the one already existing holding the sliding rough focus barrel in place. That is probably the only con on both scopes. It would have been nice if they had thumb screws on all three of those positions....I HATE the idea of using allen wrenches in the dark and chancing droping them. I also read through some of the other reviews....there were a couple of bits of misinformation. This is an air spaced Achromat NOT a cheap cemented lens. For that reason this is a better optic. You can tell it is air spaced as you can see the three rectangula spacers around the lens.....this is NOT a defect but a good and normal design that most high end refractors use and do not show up in photos. Both of my scopes give nice stars although one person said they had weird stars and another mentioned their lens was placed backwards. In that case they were able to easiy reverse the optics and it works fine. Of course that should not have happened and signals a QC issue....but in my case the two scopes were well assembled and no glitches in the optics and the stars were nice and round. It is not an APO scope of course and not expected or needed at this price or as a guide scope The newer 60mm version has already seen use and like its 70mm brother works great....in fact unless you have a very long focal lengh scope it may be the better choice as long as you have a guide scope with pixels on the smaller side. But with my longer focal length scopes I like that precision. I use both with either a ASI 290 MINI or a much older SBIG STL 237 gjide camera that is slaved from my full frame SBIG camera. No issues with either camera/guide scope combination. In both cases i did fabricate longer dew shields as I refer that to having to use dew heaters. So my review is still very positive and I highly recommend the 60 or 70mm versions. Not having the 50mm version I can't comment on that one but have no reason to believe it wouldn't also be fine. In any case it is so much better than the cheaper toy-like guide scopes that are being pushed today.
Review: Very good as imaging scope for astrophotography to get a wide field.
