The Clear Sky Astro-Shooting
Astrophoto IC 1396A Elephant’s Trunk Nebula Clear Skies 20-22.
From september the 3rd to september the 5th there was very nice clear skies after a summer full of clouds. 3 days i did a single object. This time an emission nebula.
Elephant’s Trunk Nebula
A really pretty object. With my 600mm focal length and the APS-C chip it is really nice to capture. But it is even nicer with a shorter focal length.
Here the high resolution version of the astrophoto on Flickr:
Same data – advanced processing
This picture is the first one, i did with “full equipment”. Beside the Vixen ed80sf on my HEQ-5 i used the Flattener (not perfectly configured yet), the 1:10 Lacerta micro focuser.
And i used my new Optolong L-Extreme the first time in my ZWO Filter Changer. A question i have to ask myself is, if it is the best idea to use a duo-narrowband filter on a f7.5 telescope with a camera where i am forced to expose at a maximum of 180s.
Due to the fact of using the narrowband filter and being limited to 180s exposures, i used ISO 1600. As a result i had bright edges aafter stacking the frames. Possibly this is some camera glow i need to take care of in future. possibly i ll go for ISO 800 next time.
