Remote RGB filter wheel.

文章 Chanlunlun » 週三 09 3月, 2016 10:06

It takes a few days to fabricate the RGB filter wheel for Jupiter ( and, of course, for other planets) shooting.

There are lots of theory on how to make great Jupiter shot. The RGB method may be the most commended one and so I ‘ll just to give it a try.

But Jupiter rotates so fast that the change of filters must be taken place very quickly. I use a ZWO manual filter wheel + ZWO LRGB filters + DIY motor + DIY remote control software to hopefully solve this problem. Field test shows that it takes only 2 seconds to change filter.

Of course everything is not yet proved. Only when Jupiter reappears do we see whether it is worth the effort or not. I am waiting.

This is what we see on the PC mon. When click onto ”+” and “-” button the drive motor will rotate clockwise or anti-clockwise. The webcam attached onto the filter wheel will show which filter is in place. Now it’s the red filter at work.

DIY motor driver. The little bronze spur gear attached to the motor drives the filter wheel in a fast manner. It takes only 2 seconds to change from one filter to another.

Our RGB planetary camera. It is a ZWO 174mm + ZWO filter wheel + ZWO filters + DIY motor mechanics + DIY remote controlling software. The motor at RHS is for focusing. The motor at lower left is for filter changing.

This filter wheel only holds 1.25" filters. Are they sufficient to cover whole CCD area of your ATIK?

By the way this filter wheel is economic and could readily be modified.

Yes, the ICX825 sensor inside is small.
