M17 - Rays Astrograph Designer Tool

[PKay (Peter)]

I found this Excel program hidden away whilst doing some house keeping.
Thought I would put it out there again, but don't know how to add an Excel file.

For calculating ideal exposure length.

Image attached is 42 * 180s @ Gain 140 (80mm EON).



Tight Focus!

Great colours . That 1600 chip really delivers in the right hands.

Google drive and share the file?

Thanks Gents for the kind words.

Ray: Good tip.
Here is a link to Google drive where I placed the file.
It is for Excel spreadsheet.
Let me know if it works or not.

Thanks Peter. Got it. Some of those units are a challenge and not really sure what i am aiming to get. Interesting to try though. I like the "test image and measure the histogram" system but this explains the result.
