A close up from Saturday. Looks like I am getting some banding with the 2x Barlow so may need to start taking flats.

In this post, I will explain how to build a dual-purpose laptop shade / dew shield for a cost of approximately £20 (GBP). As explained in Dew Formation and Prevention, the simplest way to prevent dew forming on equipment is to shield it from direct exposure to the night sky. Using this shield will help to …
A week on, AR2529 is still going strong, but about to disappear behind the solar limb. (Click image for full-sized version).

Sun, Full Disk Hydrogen Alpha. (click images for full size). Scope: Lunt LS60THa/B1200CPT Camera: ZWO ASI174MM, FireCapture Mount: Sky-Watcher NEQ6, EQMod Processing: AutoStakkert! 2, PixInsight 1.8, Gimp 2.8 Date: 17th April 2016, 08:44BST (07:44UT) Frames: Best 10% of 1,000 Frames
Another animation of AR2529 (a sunspot), taken in Hydrogen Alpha. This is a different set of images from the previous post and shown in the normal (not inverted) colour scheme. Click the image below for the full-sized view (you might have to wait a few moments for it to load). Scope: Lunt LS60THa/B1200CPT, Meade 2x Barlow …

Animation of AR2529 (a sunspot), taken in Hydrogen Alpha. The image is inverted so the sunspot appears white against a dark background, as this allows much more of the image detail to be seen. Scope: Lunt LS60THa/B1200CPT, Meade 2x Barlow Camera: ZWO ASI174MM, FireCapture Mount: Sky-Watcher NEQ6, EQMod Processing: AutoStakkert! 2, IMPPG, PixInsight 1.8, Gimp 2.8 Date: 3rd April …
A solar prominence animation in Hydrogen Alpha (with the Earth shown approximately to scale). This is my first attempt, as a bit challenging to create as there were a lot of high clouds drifting through. This has created some long gaps between frames and a few odd artefacts around the prominences and disk where I …

In this third post explaining my PixInsight workflow, we’ll be taking a look at dealing with Dark Current by creating and applying dark frames using a Canon EOS 500D. I think it is fair to say that creating a good master dark in order to calibrate flat and light frames is one of the more …
This is the second in a series of posts explaining the general workflow I follow when using PixInsight. We’re going to take a quick look at improving our bias frames still further, using PixInsight’s SuperBias module. Read on for more on about creating a good super bias. (If you’ve arrived part way through, start the series …
