I purchased this because of the price point. I was definitely impressed with the build quality. It really is a sturdy little scope. I liked it so much I got a 70mm version of it. Both have the zwo EAF focusers on them. The 70mm has an IMX183C and the 80mm has IMX571MC imaging cameras on them. I am considering getting a second 503 80mm and running a dual imaging system off the same mount. Attached are 2 images I've taken, M42 being the last image of 2023Scope 503 80mmRosetta and galaxies photo Altiar 183mc pro cooled / SVBony uv-ir cut filterM42 Risingcam IMX571MC cooled / SVBony uv-ir cut filterBortle 8-9 skies.

This is an excellent scope for the money. I've had mine for two years now, and learned a tremendous amount about astrophotography with it. The pictures I've included were taken with a ZWO ASI533MC Pro cooled camera under a Bortle 4 sky. You will need to add a filter to get the best results. The Orion shot was taken with an Antlia Triband filter, and the Rosette with an Astronomik L-3 UV/IR cut filter. The filters help with the doublet scope's chromatic aberration and the camera's near-ultraviolet sensitivity, which produce blue halos around bright stars, and with the sky glow I get with Albuquerque 20 miles west of me.For the money this scope is absolutely terrific. The workmanship on mine is flawless, and the only problem I had initially was that the objective was very dirty.The scope is only part of getting good pictures. You will still have to invest in the best mount you can afford, and a good camera.

I recently upgraded my entire astrophotography setup. I went big on the mount and decided to go for a mid-range option on the scope. I am incredibly happy with this scope. It's very easy to use and the optics are incredible. The attached shots of the moon were from my first night out with this scope.Shots of stars show great performance all the way to the edge. I've recently seen a few videos on YouTube with reviewers comparing this scope to ones costing 2-3x and there is barely any difference in the final images (usually limited to minor imperfections around the edge). I also have a higher-end triplet, and I confirm these findings.Unfortunately, it's been cloudy almost every weekend since I got this, but I look forward to testing more with DSOs.This is a shockingly good value. Pull the trigger! You won't be disappointed.
