	~~This is my current~~ telescope setup:		Current telescope setup:



			The main scope is a 71mm diameter Petzval-style 4-element refractor with a focal length of 490mm.

			The red box at the end is an automatic focuser and is attached to the scope's focusing knob.

			Using an off-axis guider, the blue Touptec camera is at a 90-degree angle of the image train.

			After that, at the end of the optical path is the main camera, an SV505C (resolution 2712 x 1538 pixels)

			On top is a small computer which allows me to fully operate this rig remotely.

			The white contraption underneath is a SkyWatcher HEQ-5 Pro mount. This helps to counteract the earth's rotation so that objects remain fixed in the camera.

			Previous scope:


			Until 2024 I used this scope, but I have since sold it. The details are still here for reference.

This is my current telescope setup:

The main scope is a 6" diameter (15cm) Schmidt-Cassegrain with a focal length of 1524mm.

Just visible at the back is a much smaller 4cm diameter guide scope with a focal length of 160mm.

The red box at the end is an automatic focuser and is attached to the scope's focusing knob.

Underneath that, at the end of the optical path is the main camera, an SV505C (resolution 2712 x 1538 pixels)

Underneath that, with the round cable, is a small computer which allows me to fully operate this rig remotely.

The white contraption underneath is a SkyWatcher HEQ-5 Pro mount. This helps to counteract the earth's rotation so that objects remain fixed in the camera.
