This scope will make your astrophotography a real joy
I have the svbony 503 80ED and the sv550 122mm, I started astrophotography seriously at the end of last year.I'm a real fan of the Svbony brand.
Best choice for both visually observing and astrophotography
The SV503 telescopes are awesome for this price-range. And especially the 102mm is the best choice for both visually observing and astrophotography.
Excellent ED doublet refractor
I own this 102ED myself, and I am planning to add a mono camera and filters ouch instead of getting a triplet/APO
Suitable for beginner astrophotography
I purchased the 503 80ED last year after having entered into AP and had no idea what a doublet was. I found that the quality was great considering it was my first refractor.
The performance for visual astronomy has been great.
I bought the 102 version last month. I'm under Bortle 8 skies, so even my C6 has contrast issues . Yet, the Svbony, under full magnification 200x (using your favorite Baader Zoom and barlow set) at Jupiter and Saturn worked very well.
SV503 Package Deal
As someone new to astrophotography, I'm quite pleased with my choice of the SV503 80mm scope package from SvBony.
Here's my current setup:
SV503 Scope
SV193 Reducer/Flattener
SV165 Guide Scope
Sky-Watcher AZ-GTi Mount
Canon T3/1100D DSLR
ZWO ASI120MM-S Monochrome CCD
MacBook Pro (16-inch, 2019)
KDE Kstars/Ekos
The SV503 is pushing the load limit on the AZ-GTi mount, but everything is working together smoothly. Last night, with active guiding in Ekos using the ZWO CCD, I was able to capture 120-second exposures of the Horsehead Nebula and get perfect pinpoint stars in the field one after another. I'm excited, and looking forward to many productive sessions while I explore and learn the heavens.
