I’ve done less astro-photography so far this year, due to an unfortunate combination of equipment malfunction, purchase of two new ZWO cameras, weather conditions and health issues.
So I decided to revisit some of the images I managed to take earlier in the year with the new cameras, to test new processing procedures.
First up is this Lunar image, which is from a different original file as this earlier post from the same night, using different image stacking and processing procedures.
Object Details:
Moon Visual magnitude: -11.8
Apparent diameter: 32.7 arc min
Actual diameter: 3475 km
Distance: 365,487 km
New Moon: +17 days
Image:
Exposure: AVI capture of 2 seconds @30 fps.
Date: 2017-02-02.
Location: Leumeah, NSW.
Sky: outer suburban.
Cloud: partly cloudy.
Processing software: PIPP, VDub, Registax5, Gimp.
Cropping: yes.
Gear:
Imaging telescope: Skywatcher Esprit 120ED Super APO triplet refractor.
Focal length: 840 mm, focal ratio: f/7.
Imaging camera: ZWO ASI 071MC Pro.
Telescope mount: SkyWatcher EQ6-R.
Polar aligning: QHYCCD PoleMaster.
Field flattener: yes; filter: no.
Imaging software: SharpCap 3.0
Observing Notes:
This session was my first experimental use of two new astro-cameras.
The image was taken less than 48 hours after a lunar eclipse, which was completely clouded out at my locality.
