Nice job fiming this. Saturn is more than 800 times the volume of the Earth. Saturn is also more than 9.5 AU from the Sun and has at least 61 known moons.

What was the TouCam equivalent to (eyepiece). I have a Celestron Astromaster 114AZ. I saw ur most recent vid as well, great views!

I never know how to answer that. Basically, the image scale (in arc-minutes per millimetre, say) is a direct function of the focal length. Our eyes use a focal length of 17mm and this telescope has a focal length of 900mm, with a 2.5x Barlow that's 1800+450=2250 mm. That's 132 time greater.

This is a really good video
I am doing this with a webcam too
How did you manage to focus the planet through the Barlow Lens using the webcam?
What make is your telescope
The Barlow you used was good enough to help clarify and magnify the planet

Thanks! I focused by watching the preview screen on the laptop. More recently, I used moon craters to focus on and then moved back to Saturn. I now have a little motor drive that keeps me more or less pointed to Saturn, so focusing is a bit easier. It's a Celestron PowerSeeker 114EQ, FL=900mm. I used the 3x Barlow that came with the scope, a plastic bodied flimsy looking thing. This year I used a TeleVue 2.5x Barlow and I modded the webcam to RAW frames, giving a much better result.

No, no colour filter, just the cheap and nasty plastic Barlow 3x lens that was included with the scope.
