A second attempt at NGC 3660 and friends, previously imaged here, with the longer focal length of the Cassegrain (4500 mm) at the IAS Hakos Observatory, Namibia.

Oddball Planetary Nebula
Imaged at the IAS Hakos Observatory, Namibia with the 20″ Philipp Keller Cassegrain at full focal length of 4500 mm, f/9, this oddball object is listed both as a galaxy (PGC 49877) and a planetary nebula (Fr 2-8).
Quoting from Planetary Nebulae in the Solar Neighbourhood: Statistics, Distance Scale and Luminosity Function by David John Frew
Fr 2-8 (Fr 1400-5102, AM 1357-504, LEDA 49877). This small nebula, about 2′ across, was found serendipitously from SHASSA field 057, while measuring a Hα flux from the nearby PN MeWe 2-4, and has been confirmed spectroscopically as a high-excitation PN, with the 2.3m MSSSO telescope. The position is coincident with the SIMBAD ‘galaxy’ AM1357-504 (Arp & Madore 1987). It had been independently noted as a PN by Cˆote et al. (1997), but no details were provided in their paper.
Interestingly enough, the team around IAS member Uwe Glahn observed this object visually at Hakos back in 2009.

Results from the second night at the IAS observatory on the Gamsberg plateau with the 28 inch Newtonian “Wolf-Peter-Hartmann-Teleskop”, adding to my growing catalog of cometary globules.
Alas, sky flats at dusk didn’t work well, so some of the dust struture seen here may be artefacts of the calibration and gradient removal.

First result from this year’s trip to Namibia, including two nights at the IAS observatory on the Gamsberg plateau using the mighty 28 inch Newtonian telescope for astrophotography. I came across this field of view when observing the supernova SN 2026cff in NGC 3660 with the IAS remote telescope and noticed the near-by, peculiar Hoag-type galaxy PGC1000714 with its ring structure.

Continuing with the CGs, this one took really loooong, from mid January to mid February. Alas, CG season is also rain season in Namibia. Good for the country, but not so much for astrophotography.

As always, more details at Astrobin.

Another CG image, completed just after Christmas Day, showing CG 15 (lower right) in Puppis and CG 16 (upper left) in Carina. Two more for the growing catalog of CGs here.
More details at Astrobin coming soon.

CG season is also rain season in Namibia, so it took a while to gather enough data for image, adding to the growing catalog of CGs here.
More details at Astrobin coming soon.

Difficult processing with these data: separating stars and galaxy with StarXTerminator doesn’t work well here, too many artefacts. So all the stretching was done with the starfull images, with just a bit of star reduction on L, to preserve the many little, mostly blue stars in the arms of NGC 300.
