TipswithSVbony
Q: only buy the SVBONY SV503 ED telescope is enough for doing astronomy photography?
A: No, this is just a beginning.Only the Telescope Tube, you can do nothing. You need to prepare some accessories for it. Then set up all the accessories with the telescope tube, then do the observation or astrophotography.
Q:Only using the SV503 do Moon observation?
A:I don’t recommend you start astronomy with SV503, you can start to buy a small telescope. That is enough.e.g. sv501p telescope 。
If you really want to start doing Moon observation or solar observation (you need a solar filter) with the SVBONY sv503, then here are the accessories you need.
Diagonal
Eyepiece
Finder scope (if you want one)
