I didn't see it live myself and only found about it due to posts on social media. I then remembered it might have been caught on my camera so quickly downloaded images to make a short video!!

Venus and Mercury on 9th March from Oxfordshire, UK. I've been clouded out the last two evenings so this is the closest I'll be able to get them. The star top right is Algenib in Pegasus. A 6s exposure on an Omegon clockwork mount with a Cinesoft Subtle filter. #astrophotography #astronomy πŸ”­

Jupiter, Ganymede and Io

My latest attempt at Jupiter from last night. Ganymede (top left) has just emerged from behind Jupiter and Io (bottom right) has just transited Jupiter and is casting its shadow. 300mm F/4 Newtonian with 2.5x PowerMate and ASI662 camera with contrast filter. #astronomy #astrophotography πŸ”­

I love mine as a quick and easy option for some imaging and to practice processing. Great for holidays and day trips πŸ˜€

Could say that about any imaging. I’ve imaged M42 with all sorts of cameras and set ups, some more automated than others. Processing the gathered data is always different and where the skill lies. The DWARF II gives satisfying results for beginners in a portable package.

Messier M42, Orion Nebula, taken with a DWARF II smart telescope.

The DWARF II smart telescope is a surprisingly capable little thing. Here is an image of M42 taken a couple of nights ago from my very light-polluted back garden. This is 100x15s exposures, stacked within the device and some post-processing in PixInsight. #astronomy #astrophotography πŸ”­

Jupiter with Callisto and Io taken through a 127mm Maksutov-Cassegrain telescope

I've never been much of a planetary imager so I thought I'd try and improve! Jupiter this evening using a 127mm Maksutov-Cassegrain and a ZWO ASI662 camera. Best 5% of 5000 frames stacked in AutoStakkert and processed in PixInsight. Io (left) and Callisto visible too. #astrophotography #astronomy πŸ”­

Finally got a clear night to try my new ZWO ASI662 colour astro camera. This is a mosaic of 28 images using a 12" F/4 Newtonian telescope. Best 100 frames from 200 in each video stacked in Siril, stitched in Microsoft ICE, post-processed in PixInsight. #astronomy #astrophotography πŸ”­

An Announcement from Iron Maiden - Iron Maiden An announcement...

Nicko McBrain is stepping back from touring with Iron Maiden. Tonight will be his final gig. It's been a privilege to see him with the band the past 36 years during which time I've seen them live around 25 times. I wish him all the best for the future. www.ironmaiden.com/an-announcem... #ironmaiden

I see mistaking Venus for a UFO season is upon us once again. The other place is full of out of focus videos of Venus and comments like "then another appeared in the East", i.e. Jupiter, as well...

Waning Moon taken with a DWARF II smart telescope.

Waning Moon taken with a DWARF II smart telescope.

Autumn is an ideal time to image the waning Moon as the ecliptic makes a steep angle with the horizon so it's high in the sky at a sensible time. This was taken last night with a DWARF II from Oxfordshire, UK. A stack of 50 x 1/500s images post-processed in PixInsight. #astronomy #astrophotography πŸ”­

Very sad day. Paul will forever be the voice of my teenage years. Killers was the first LP I ever bought. Original Iron Maiden singer Paul Di'Anno dies www.bbc.com/news/article...

Real. That’s the anti-tail, dust left behind in the comet’s orbit and illuminated by the Sun.
