I have a large dovetail bar on the top of my Ritchey that I connect accessories to, like guide scopes. My recommendation would be to not use a Celestron product unless it’s an eyepiece. πŸ€·πŸ»β€β™‚οΈ **Q: Will this guide scope work for a c8 ota at f6.3 (1250 mm fl) on an avx gem?** A: Most Astrophotography with C8 will use 60mm guide scope that is a starting point for guiding C8 with 6.3 reducer. **Q: Will the zwo asi120mm mini work ok with this scope?** A: Yes **Q: Would this scope be a good match with the skywatcher evostar 72ed focal length of 420mm?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Guide scope *by R***Y on December 6, 2024* Best bang for the Buck. works as advertised. ### ⭐⭐⭐⭐⭐ great design, high quality *by M***E on August 13, 2019* great guide scope for the money. works perfect with my ZWO ASI 120 camera. wish there was a better way to focus it. ### ⭐⭐⭐⭐⭐ If you're looking at cheaper guide scopes, hoping to get something that works, skip it and get this *by A***Y on June 15, 2023* Astrophotography is an expensive hobby. There. It's been said. Now that that's out of the way, I fully understand that we want to cut corners wherever we can and as someone who bought this after buying two other, cheaper scopes, can say that this isn't that corner to cut. Double that sentiment if you are tracking. It's not that the optics are that much better than the other, cheaper ones at some hugely measurable spec. It's that this one is well built and accurate. Example: two other spotting scopes that I purchased both had the same two issues: If you had the camera connected while you are focusing the scope, any of the stars in view will rotate around, showing that the camera mount to the focus threads, to the lens aren't square/parallel. Once you have it focused, it really isn't that big of a deal but something to think about. Tie that to the base on the others weren't exactly square to the tube and no matter how much you adjust them, it's pretty tricky to get them to align with where your main scope is pointing. Yes, you can make them work and yes, you can still track with the others. Both of those take more work than is necessary. With this one, it's just lined up and square. First setup for me was to connect it to the dovetail, focus it, make some lateral adjustments, and I was off to the races and haven't had to adjust it again. If you're just getting started in the astrophotography journey, this sounds like not a big deal. Trust, I thought the same thing when I started. Once you're at a point where you've got your routines, it starts to be one of those things that you don't want added to the huge list of other things you have to think about and adjust to do this hobby that we all hate except for the time we're looking at these pictures we are taking of things so far away that the objects in our pictures are from a time before any of us were born, some of which before people. ## Frequently Bought Together - ZWO 30mm f/4 Mini Guide Scope for ASI Cameras # 30120 - ZWO ASI120MM-Mini 1.2MP Monochrome Astronomy Camera, Compact, 1280x960 CMOS Sensor, USB2.0 Type-C, ST4 Port, Black - SVBONY Universal Dovetail Base, Finderscope Mount Bracket, for Installation of Finder Scope for Optical 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.co.th/products/72018928-zwo-30mm-f-4-mini-guide-scope](https://www.desertcart.co.th/products/72018928-zwo-30mm-f-4-mini-guide-scope) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-10*
