NGC 2070 – Tarantula Nebula – First Light IAS Remote – Nov 2021 – Modified Hubble Palette 1a

IAS – International Amateuersternwarte e.V. – Hakos Observatory, Namibia

First light of IAS remote telescope “Klein-Lukas”, Details at Astrobin.

Remote team: F. Hund, J. Obstfelder, L. Demetz, M. Mushardt, T. Klemmer, T. Winterer, M. Junius

Alas, the setup had to be done in a hurry with many problems and the Epsilon is badly collimated at this point in time. A planned maintenance trip now most likely faces travel restrictions.

So please bear with the image quality, especially on the left side. ;-)

IC 417 Emission Nebula and Friends – Ha BW – Nov 2021 v1

A completely clear night – not that many of them lately – provided several hours of H-alpha to catch the nebulosities above. Meanwhile I switched from the Optolong LRGBSHO filter set to the new Baader CMOS-optimized filters. At least H-alpha seems to work better in the combination with the Esprit 100 ED and QHY 268M, but still some problems with the flats.

See Astrobin here and here for details.

Fagradalsfjall Volcano Eruption #1

A trip to Iceland in September, with high hopes to see the Fagradalsfjall volcano in action. At first a bit disappointed, because activities stopped just before we arrived, we were lucky on the last but one day and the fourth hike into the volcano area. A splendid display of lava fountains and flows from the late afternoon into the night. More images/videos to come!

NGC 6888 – Crescent Nebula – Ha

NGC 6888 – Crescent Nebula – Jul 2021 – Ha BW

Still a work in progress, mastering the QHY268M with the Optolong LRGBSHO filter set. Seems like a setup with reserved filters is required for the Esprit 100 ED with the original flattener, in order to avoid strange reflections from bright stars such as Deneb or Sadr. Shooting a familiar target here.

NGC 7000 – North America Nebula and IC 5070 Pelican Nebula – Ha BW – Jun 2021 Mosaic v1

Continuing the explorations with the QHY268M, a two panel H-alpha mosaic. And the first time I used NINA to control the imaging session.
