oaCapture QHY5L-II support

Posted on August 13, 2014 by james

Note quite there, but very nearly (for the mono camera, at least).  The splitting of the frame clearly means there’s an issue somewhere, but it can’t be too hard to get sorted.

oaCapture on Raspberry Pi

Posted on August 13, 2014 by james

I’ve finally done the (small amount of) work to get oaCapture working on the Raspberry Pi.  There genuinely wasn’t that much to do.  I was surprised how easily it all worked.  It does struggle to keep up with high frame … Continue reading →

A second attempt at Jupiter

Posted on August 13, 2014 by james

A week after the first, I managed another session on Jupiter.  I feel exceptionally out of practice this year, though I’m happier with the detail this time around. And another animation.  Watch the seeing completely go to pieces just after … Continue reading →

Jupiter at last!

Posted on August 13, 2014 by james

DIY dew controller

Posted on August 13, 2014 by james

Time for a new white light solar filter

Posted on August 13, 2014 by james

I’ve had a white light solar filter made from Baader ND5.0 film (two, in fact) for several years and one of them was starting to look rather tatty so I decided it was time to make another.  Baader’s instructions suggest … Continue reading →

Collecting meteorites from rainwater

Posted on August 13, 2014 by james

Allegedly it is possible to collect tiny fragments of meteorites from rainwater.  The story goes that they can drift in the atmosphere until they get caught in the rain and end up falling to the ground.  By trapping the flow … Continue reading →

QHY5 support in oacapture

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 →

Time for a catch-up

Posted on August 13, 2014 by james

Quite how half a year has passed since I last wrote anything is beyond me.  Work, life, family and all that jazz seem to have taken over from the little box in the corner of my office. Time to start … Continue reading →
