Choosing among astrophotography cameras & adapters comes down to a practical fork: do you want a modified camera body with a listed Canon EF mount, or a dedicated planetary-and-guiding camera? The Canon EOS Rebel XSi and SVBONY SV305C Pro sit close together in price, but they serve different workflows. Here is the useful split: Canon suits shoppers who want a full-spectrum camera body, while SVBONY is the more focused choice for planetary imaging and guiding.
Quick verdict
Choose the Canon EOS Rebel XSi when a modified camera-body workflow and LiveView focusing fit your setup. Choose the SVBONY SV305C Pro when planetary imaging and guiding are the main tasks. Their prices are relatively close, but the more important difference is the kind of camera each one is designed to be.

Where each camera wins
Canon EOS Rebel XSi
Canon is the stronger fit for a camera-body workflow that includes a Canon EF mount and full-spectrum astrophotography modification. The description also places it in outdoor photography, with custom white balances and filters named as part of that use. That gives the Canon a broader photography brief than a camera positioned specifically around planetary capture. It also suits shoppers who are comfortable using LiveView, because accurate autofocus or manual focus is specified there after the IR-UV filter removal.
SVBONY SV305C Pro
SVBONY is the clearer choice when planetary capture and telescope guiding are central. Its listed 1920×1080 capture rate of 107FPS provides a specific planetary-imaging workflow, while the ST4 guiding interface and stated PHD2/ASCOM support address guiding directly. USB 3.0 transmission, Any Area ROI, 12-bit output, and HDR are also part of the camera's listed imaging controls. These details describe a dedicated astronomy-camera approach rather than a conventional interchangeable-lens body.
Product notes
Canon EOS Rebel XSi modified for astrophotography ( full spectrum ) body only
The Canon EOS Rebel XSi modified for astrophotography is the more fitting pick for a camera-body workflow built around a full-spectrum conversion and a Canon EF mount. Removing the IR-UV cut filter is the defining change, and the description also supports outdoor photography with custom white balances and filters. LiveView is important here: after the modification, accurate AF or MF is tied to LiveView rather than the eye-level optical viewfinder. The practical limitation is the package condition and scope: it is used, the rear screen has scuffs, and the body-only listing excludes a lens, SD card, cables or cords. At $160.00, the Canon also carries the lower listed price, but the missing accessories mean the setup requires camera-body essentials beyond the box.
SVBONY SV305C Pro Planetary Camera CMOS Sony IMX662 Sensor for Astrophotography
SVBONY SV305C Pro makes the clearer case for a dedicated planetary astronomy camera with a stated guide-camera role. The Sony IMX662 CMOS sensor and 1920×1080 capture at 107FPS are aimed at the planetary workflow described for the camera, while the 12-bit ADC and HDR are listed as part of its imaging design. The 2m USB 3.0 cable and 128MB DDR buffer add concrete capture hardware to the package. The limitation is specialization: the title and description center on planetary imaging and guiding, so it is less natural for someone seeking a Canon EF camera body for outdoor photography with custom white balances and filters. At $179.99, it is $19.99 above the Canon.
Final choice by use case
- Choose Canon EOS Rebel XSi for a Canon EF-mounted camera-body setup, full-spectrum modification, or outdoor photography with custom white balances and filters. LiveView focusing needs to suit your workflow.
- Choose SVBONY SV305C Pro for planetary astronomy and a dedicated guiding path. The ST4 interface and PHD2/ASCOM support make its intended role clear.
- If the deciding factor is the camera type, Canon is the modified body, while SVBONY is the purpose-specific planetary and guide camera.
