Dealing with a backlog of observations here: some nice sunspots imaged with a 5-inch SCT in IR 804nm. The image is not rectangular because I cut out a sensor dust mote. (Click to enlarge) … Continue reading

This is an image I took in March but have only just got round to processing. (Click to enlarge) … Continue reading
A lot of activity visible. Very spotty in white light as well, but didn’t get a white light image. … Continue reading
Here’s a classic object for this time of year, the ghostly Owl Nebula, in a false-colour image taken through H alpha and OIII filters. It gives the impression of two spherical shells of gas displaced from one another, but, unlike … Continue reading
It’s the time of year for solar observing again, and there was a nice active disk yesterday in both H alpha and white light. Here’s an image taken by the method I’ve been using for a couple of years now, … Continue reading
This is an LRGB image with the L from a light pollution filter, but it is rather undersaturated as the data is dominated by the luminance; true RGB from such a light-polluted environment as I work in is probably impossible. … Continue reading
The comet was slightly closer to M31, and now clear of the spiky tree. M31’s companion galaxies also show up here. You can see the atmospheric dispersion effect in the star images near the horizon. This image is oriented along … Continue reading
Here’s the comet in a spiky tree in a DSLR image, at the opposite end of the field from M31. … Continue reading
The seeing looked steady visually on this occasion, but on-screen it was rippling very fast at a small scale (not surprising for 27º altitude). Three sequences of RGB were captured, and all combined for a 14 minute run, interspersed with … Continue reading
Tonight I finally obtained an image of C/2011 L4 (PanSTARRS), after all these cloudy evenings. There was a gap in the cloud for about 30 minutes which I exploited. The comet is going behind a nearby fir tree during the … Continue reading
