How long should your subs be? How much should you cool? What gain should you use? How can you get the most out of your CMOS camera? Dr Robin Glover of SharpCap talks us through the science behind deep sky astrophotography using today's modern CMOS imaging cameras.
In this talk Dr Glover brings up differences between CCD and CMOS, noise in images, temperature, sub length and how to make the most of our imaging time to get the best images. Covering subjects such as 'how long do your exposures need to be?' and 'How much should I cool my camera?'. A very technical talk that might seem intimidating to new-comers, but still provides invaluable information. I'm sure you'll come away from this lecture having learned something!
There are a couple of transitions within the video whilst I had to stop and restart the camera (limited movie length!) but since the audio was still recording; nothing has been lost! I hope you do forgive me.
The Practical Astronomy Show 2019 was an astronomy convention held in Kettering, Northamptonshire on the 9th March 2019. Vendors and accomplished individuals from the hobby were in attendance and talks were available from the likes of Paul Money (AstroSpace), Niels Haagh (TTS), Gary Palmer, Dr Robin Glover & Damian Peach. Suppliers such as Tring Astronomy, The Widescreen Centre, Rother Valley Optics, Altair Astro, 365 Astronomy and many more.
The footage and audio was recorded by myself with permission from the organisers and the speakers. Damian Peach's talk on High Resolution Astrophotography was also recorded and is available to watch here https://youtu.be/puoh1ikzonA
