269c sensor analysis
Posted: Sat Dec 12, 2020 10:36 pm
I'm really hoping someone can help with this.
I've been trying to run the sensor analysis for my Altair Astro 269c via my MiniX computer connected to the Dell laptop (W10) that controls my rig.
I have tried with natural light in a massive variety of brightness levels, a flat panel with varying layers of paper (printing paper and bleached greaseproof 'see through' paper) always with the same result. It starts off ok and then gets to the point where there is either too much light or too little light and aborts. The difference can be just one sheet of bleached greaseproof paper!! - It just will not work.
I have tried varying sizes of sample 'box' and always with the same result - failure.
Surely the whole idea of the sensor analysis is to make it easily useable, so either I am doing something wrong or....
Well, I can't think what!
Please help - all I want to do is analyse the sensor and then use that to judge the best exposures on any given night - if we see a clear night again sometime of course!
Thanks in advance
