<div class=""><p class="">Hi All,</p><p class="">I'm a retired software developer (mostly Java, C, and
some C++). I've been using KStars on a Raspberry Pi
(Ubuntu), since I got interested in AP, (around 2020).
Back in late 2021 I wrote an optimal exposure time
calculator (in Java), based on the work of Dr Glover. I
just got to thinking that it might be a nice addition to
KStars, and today I found a request for it:
<a href="https://indilib.org/forum/wish-list/5300-exposure-calulator.html?start=12" target="_blank" class="">https://indilib.org/forum/wish-list/5300-exposure-calulator.html?start=12</a></p><p class="">My current code is pretty simple but has no user
interface. It uses a few classes for configuration, a
table of sensor gain to read noise, observation site
location SQM value, optics F ratio data, and
(experimentally) a filter bandpass table. The code just
iterates through all the combinations of the inputs to
output tab delimited data to the console, that I copy into
a spreadsheet.</p><p class="">Keep in mind that the exposure time calculations are
optimal (per Dr Glover), but not necessarily practical.
I've seen a slow optic, with a filter, in very dark
skies, produce a optimal sub exposure time calculation
that exceeded 3 hours.<br class="">
</p><p class="">If this were integrated into KStars, we would obviously
need to provide a means for a user to input some of their
own configuration information.<br class="">
</p><p class="">Please let me know if you'd like to consider integrating
this into KStars, (I would need coaching/help if I were to
take this on). <br class="">
</p><p class="">Example output:<br class="">
</p><p class="">I have my code configured for the read noise for my main
imaging camera, (a ZWO ASI-071 Color), SQM data for four
observation sites. F ratios for four optics, and bandpass
info for two filters. And I'm using an allowable noise
increase of 5%.<br class="">
</p><p class="">A small section of the output provides this information
for a given site, optic, and sensor gain selection:<br class="">
