Animation of R-CrA Variable Nebula

[Pilgrim (Igor)]

I want to share a lucky find. Since July, I have been shooting a complex of nebulae in Corona Australis. Inspecting nightly sums accumulated so far, I decided to check if any variations are detectable at this time for my humble setup and got pretty surprising result.

Total exposure is 12h 17m over 11 nights.
Average subframes is 67 per night (1 night = 1 frame)
Each subframe is 1 min @ iso1250, Canon EOS Ra + TAL250K (10" Klevtsov OTA) with 0.7x reducer-flattener, Balcony observatory, Brisbane, Toowong (Bortle 7 sky)


Final static sum is not processed yet because I keep imaging it.

That's amazing. We sometimes think of space being so static; it's anything but!
Really incredible, cheers for sharing.

Thanks, friends, for your kind words!

I was amazed by the result too, it was supposed to be a static picture, but I accidentally remembered about this feature of the nebula and decided to see if there is any night-by-night dynamics.
