ISS, Limits of Current Equipment
September 18th, 2009
I had another go at the ISS last night, this time with the 2x barlow in place in an attempt to achieve higher magnification :
- Exposure 1/1500
- Gain 50
- Brightness 60
I think that’s gone a bit above the limit of the webcam. I can’t increase the exposure any further without getting blurring, which means I have to increase the gain which in turn produces to much noise. Still it has been a very production week for imaging for me.
The next experiment now I have the UV/IR cut filter is to look at using EOS movie record to capture the AVI through the barlow and see what magnification I get with that combination. The better chip and better control should allow for a better image, but I think any targets will be to small. I may need to keep an eye out for a higher magnification barlow for this option.
I also want to try the webcam, through the barlow but with my 0.6 reducer attached as well. I may well be getting carried away there though. The ideal would be an imaging source camera, add yet another item to the shopping list!
