astrophotography

Wednesday 26th May 2021 would be the first lunar eclipse in three years, although it was only barely total, with the Moon completely inside Earth's shadow for just 14 minutes or so. But as usual, I would bite off more than I could likely chew.

Sky-Watcher Star Adventurer 2i Review

The Sky-Watcher Star Adventurer 2i is an updated version of the original Star Adventurer tracking mount. It brings the App based control of the Star Adventurer Mini (SAM) to its slightly larger brother. Refer also to my previous reviews of the Star Adventurer and the SAM as both are still highly relevant.

Southern Cross and 'The Pointers'

Although I already have an automated observatory for deep sky imaging, with some time and inspiration in isolation in early 2020, I setup my smaller equatorial mount in my 'darky sky' backyard for some widefield imaging with a QHY367C CMOS camera and a Canon 85mm lens, to capture this stunninng view of this region of sky, inspired as I have been for the last 25+ years by Akira Fujii's own famous image of this iconic constellation. In total, I captured 20 hours of exposure across three panes of the mosaic, including additional frames to capture the red nebula through a hydrogen-alpha filter and multiple layers of blurred stars through soft effect filters.

Eclipsed! is my first significant solo exhibition, which features images from five of my local eclipse chasing efforts and large format prints of the stunning results I captured at the Great American Eclipse in August 2017.

Following my review of the Star Adventurer, Skywatcher have now introduced a "mini" version of their astrophotography and timelapse platform in a smaller and app controlled version. This review describes my first month using 'SAM', which proves to be very easy to learn and use. Control via the Skywatcher app is intuitive and effective, the mount itself is very compact and it delivers impressive tracking performance for its size. In short there's a lot to like. Read the full review below.

Skywatcher Star Adventurer: Review

Skywatcher were not the first to offer portable tracking mounts but the Star Adventurer unit is a very capable and complete package. It is heavier but also has a more substantial payload than the competing options and it did feel much more comfortable supporting my full frame Canon camera and 200mm lens. Once you go beyond wide angle lenses, tracking accuracy still limits you to quite short exposures but a lot can be achieved with this portable 'track and stack' approach. The combination of flexible tracking rates, quality built-in polar scope and latitude base plus the suitability for timelapse should make this quite an attractive option.

Comet Lovejoy C/2014 Q2

What a ripper of a comet! Another Christmas special discovered by Australian comet hunter Terry Lovejoy. In the days after Christmas I enjoyed a several late nights photographing this comet and its beautiful tail. So much fun but so much data my computer was grinding to a halt!

I've used a few modified Canon DSLR cameras over the years for my astrophotography, including an Astro40D from Central DS which I used for many years of widefield astrophotography including one of my favourite ever images of the Southern Cross region.

With a new home (at least part-time) under dark skies I decided it was time for an upgrade and took the plunge with the CDS-5D (see disclosure below). This is my review of the camera, which will be updated with more tests and images.
