A short while ago I posted about the problems when combining Xcode’s -Wall and -Werror flags with pkg-config to get include directory flags. I’ve just been through my configure script doing the necessary work to replace the -I flags with … Continue reading →

Posted on April 23, 2017 by james

Planetary imaging on a MacBook/OSX

Posted on August 13, 2014 by james

Well, ok, so I’ve not actually done it, but it should at least now be possible using oaCapture. Using a bundle of bits from the macports repository I now have oaCapture building on 64-bit OSX and it appears to work … Continue reading →

Posted on August 13, 2014 by james

Posted on August 13, 2014 by james

Support for the QHY cameras is somewhat tricky.  There are all sorts of different versions of firmware floating about, not to mention various different versions of the open source interface library.  Even more awkwardly, whilst many other manufacturers have perhaps … Continue reading →

Colour histogram and reticle for Linux capture app

Posted on October 18, 2013 by james

Progress, progress… Here’s my reticle and the colour version of the histogram. I may add some options for changing the style of the reticle and splitting the histogram into three, but those are for later. I also killed a few … Continue reading →
