by on Nov.30, 2016, under Astronomy Blog

My Sky Diary for December 2016 is now available for free download from my Web site.
This includes details of two comets just starting to make an appearance, COMET 45P Honda-MrkosPajdusakova and COMET 2016 U1 NEOWISE. This last comet starts the month very close to the spiral galaxy M51 in Canes Venatici. I’ll post more details about both comets during the Christmas holiday.

Apollo 11 landing site and other lunar treasures.

by on Nov.19, 2016, under Astronomy Blog

On the morning of the 19th of November 2016, I got up at half 2 in the morning. It was clear night, but a bright gibbous Moon was visible, having risen late the previous evening. So out I went to capture some images. First of all a full disk using the DSLR. moon-20161119-tifsmergedsatflat-ws

Once safely captured I got out my trusty DMK41 camera and a 1.5 Barlow Lens, to capture some detailed shots of craters and other features.

Below is the area around Mare Tranquillitatis, the landing site of Apollo 11, close to the 30 km wide twin cratres, Sabine & Ritter. I have marked the landing site, as well as the sites that Ranger 8 and Surveyor 5 “landed”. I also just managed to capture the small craters, Collins (2.4km), Aldrin (3.4km) and Armstrong (4.6km), named after the three astronauts.
The circular feature Lamont made up of wrinkle ridges, is visible towards the top.

Below is a detailed view of the 100km wide crater Posidonius, showing some of the fractures within the floor of the crater.

Below is a montage of 3 panels showing a wider area around the crater, with wrinkle ridges across Mare Serenitatis.

Below is a three panel montage of the area below Theophillus, Cyrillus and Catherina, with Rupes Altai mountain range towards the bottom.

Below is the area around Clavius, with many craterlets  on its floor, and Moretus in the southern lunar highlands.

Below are the craters Arsitoteles and Eudoxus in Mare Frigoris, located much further north.

Below is the crater Bűrg nestled within Lactus Mortis (The Lake of Death), which contains some a number of clefts and furrows.lacusmortis

And finally to finish off with a favourite, Tycho, shown at a very different angle of illumination as it was when I last took it on the 10th of November.

NNHS & Rose WI Group – 14th November 2016

by on Nov.12, 2016, under Astronomy Blog

On Monday the 14th of November I will be bringing my Tim Peake Celebration multi-media, audience participation presentation to Northampton Natural History Society (NNHS) Astronomy Section.
CelebrateTimOn that evening NNHS are being visited by The Northampton Town Roses Women’s Institute.

Our very own @Flightsuit_Tim will also be joining us. Here he is inspecting an observatory at The International Astronomy Show last month.

flattimdomeOnce I’ve finished speaking, we might, given clear skies, be able to show them some sights through our telescopes.

It should be a very enjoyable evening.

by on Nov.05, 2016, under Astronomy Blog

The evening of the 4th bought crystal clear skies. So as I had recovered from my man-flu it was time to get out and do some imaging. Boy was it cold. It finally clouded over about half 2.

The double cluster known as The Sword Handle in Perseus.
Some nice orange stars showing up really well, showing these are really old clusters.

The Open cluster M35 in Gemini and the more remote open cluster NGC 2158.
