Looking at Signatures on a parliament.uk Petition

In January 2017, a petition was created at the UK Parliament petitions site with the title Prevent Donald Trump from making a State Visit to the United Kingdom. The petition became very popular, and by the time I noticed, it had 1.3M signatures. I took at look at the petition and noticed that the signature count was changing. There is some Javascript in the page that polls a JSON file that returns the current signature count. The DOM is then updated with the new count.

Following up on my first article on photography through a telescope I will share some more observations on how I have improved my skills at taking pictures on my mobile phone through the eye piece of a telescope. The telescope is a small spotting scope with a 65mm objective lens and a 20x to 60x zoom eye piece. My mobile phone is a Motorola Moto G (2nd generation) with a 8M pixel camera and a 1 -to-4x digital zoom.

Photography through a Telescope

I have recently acquired a small telescope and have been experimenting with taking photographs through the eyepiece. The telescope is a small spotting scope with a 65mm objective lens and a 20x to 60x zoom eye piece. The main focus of my attention is a pair of peregrine falcons that look like they are going to nest on the St George's Church tower, at the University of Sheffield. You can read more about them on the Sheffield Peregrines blog.

Certus Technology have an office in the Innovation Centre, Portobello, in Sheffield across the road from The Diamond building, part of the University of Sheffield. The building was constructed on the site of the former Jessop Hospital between June 2013 and December 2015. My office block has a window that looks out over the site, and for 2½ years I took a photo from the same window.

The first draft of the time lapse is here.
