What's Up, Doc?
Happy Easter from this celestial Easter Bunny! Although, many people interested in astronomy will rather recognize NGC 2359 under its more common moniker "Thor's Helmet", and would rather display it rotated by 90° counter-clockwise. However, I prefer this "natural" orientation, where north is up and the horizontal axis is parallel to the equator. It rather appears like a rabbit or bunny looking towards the right this way, don't you think?
Actually, this object is the result of a superhot, giant Wolf-Rayet star (the brighter one in the "eye") that has blown off its outer layers, which are now interacting with the interstellar medium and producing green O-III and red H-alpha emissions.
This image was recorded during a live stacking session performed during a Saturday evening barbecue at the Volkssternwarte München 😁. The optics used was a 16" Meade LX200 Schmidt-Cassegrain telescope with the Starizona SC Corrector IV and carried by a MAM-50 equatorial mount. The camera was an ASI 294 MC Pro color camera equipped with the IDAS NBZ-II dual narrowband filter. It was post-processed offline using SiRiL and Luminar 2018.
Image info:
Telescope: Meade LX200 Schmidt-Cassegrain @f/6.3
Reducer: Starizona SC Corrector IV (x0.63)
Mount: MAM-50, equatorial, unguided
Camera: ASI 294 MC Pro (-5°C, gain 120)
Filter: IDAS NBZ-II dual narrowband (O-III / H-alpha)
Acquisition: 255x 30s (1h 25 min) using SharpCap Pro (live stacking)
Correction: Flats, Darks
Post-processing: SiRiL (gradient removal, photometric calibration, denoising, binning 2x2, stretching), Luminar 2018 (touch-up)
