ASI120MM capture support

Posted on October 16, 2013 by james

Here’s capture support working in my new application for the ASI120MM, together with binning. I’m really not sure what use binning is for high frame rate image capture, but it works anyhow.

Troubles with the ASI120MC

Posted on October 16, 2013 by james

I started getting some problems with data from the ASI120MC in my capture application, with the image “tearing” or undebayered data appearing in what ought to be debayered frames as in these two examples: It turns out that the problem … Continue reading →

ASI120MC capture support

Posted on October 15, 2013 by james

I’m now able to get an image from my ASI120MC: The colour is all wrong. It turns out that whilst the header file gives the image format define as “RGB24”, it’s actually BGR24. I can probably write them to an … Continue reading →

A new Linux planetary capture application

Posted on October 15, 2013 by james

Astronomy-wise it’s been a fairly rubbish last month and a half. Here in the back end of beyond it’s been nearly permanently cloudy and there have been periods of several days where there’s been no hint of blue sky. In … Continue reading →

A 127 Mak Galaxy

Posted on October 15, 2013 by james

I’d tried and failed before, but I had to have another pop at M33. I wasn’t expecting too much as this is the sort of target for which the Mak is very poorly suited. This is 80 minutes of RGB … Continue reading →

A first visit to M71

Posted on October 15, 2013 by james

I wasn’t sure I had this cluster in the field of view initially. It’s quite diffuse compared with the Messier clusters I’ve spent the summer imaging and against a fairly dense star field it wasn’t entirely obvious. It looks lovely … Continue reading →

A stunning globular cluster

Posted on October 15, 2013 by james

I’ve not even got close to doing this justice, and it didn’t help that I lost my guide star after 30 subs or so thanks to the sky becoming hazy. I am going to have to come back and have … Continue reading →

Back into the ring

Posted on October 15, 2013 by james

I had to revisit this before it disappeared from view for the winter. Sadly dew had other ideas (time to make some dew heaters…), but not before I’d managed almost two hours worth of subs. Only 90 seconds this time. … Continue reading →

Final M27 of the season

Posted on October 15, 2013 by james

After starting to get to grips with guided imaging I had to give this planetary nebula one more crack before I move on to pastures new. So this is two and a half hours of RGB in two minute subs. … Continue reading →

Guiding for Boys

Posted on October 15, 2013 by james

And girls, and indeed astroimagers of any other persuasion. I’ve finally assembled all the bits I need to start guided imaging. Whilst I have an ST80 that I plan to use eventually, for the moment I have a Skywatcher 50mm … Continue reading →
