(IV)
Tero Hiekkalinna, Ursa (Helsinki)
The Wizard Nebula is located in the Cepheus constellation about 7,200 light years from Earth. I photographed this in two nights (October 11-12, 2022) and the light accumulated for a comfortable 7 hours and 35 minutes. The first image was processed experimentally, imitating the color scheme of the Hubble Space Telescope. Another "norm treatment". I used an Optolong L-eXtreme narrowband filter in the photo.

A mosaic of two panels by Harsosumu. I shot the fog on five different nights in October-November and both panels accumulated 5 hours and 10 minutes of exposure separately, so there is a total of 10 hours and 20 minutes of exposure.
NGC 7635, NGC 7538, M52

The Kulpa Nebula (NGC 7635) is located in the Kassiopeija constellation approx. 7100 light years from Earth. The diameter of the bubble is approx. 7 light years. The wider images also show the open star cluster M52 (lower left) and the bright Northern Lagoon Nebula (NGC 7538) in the upper left. The first two images processed to imitate the Hubble palette and the third "natural".

(IV)
Tero Hiekkalinna, Ursa (Helsinki)
I photographed the Pacman fog during one night and the exposure was 4 hours and 40 minutes. I used the Optolong L-eXtreme dual narrow band filter in the photo. The first two images have been processed as if imitating Hubble's color scheme.

LDN673
3.9.2022 at 22.16 - 02.24 - Orimattila, Artjärvi, Tähtikallio
(V)
Tero Hiekkalinna, Ursa (Helsinki)
I photographed this dark fog at the Deep Sky meeting of URSA on Tähtikallio in Artjärvi on the night of SA-SU. On the weekend in question, there was a 30-year anniversary meeting and there was a really nice crowd and the Halo Deck was almost full of telescopes. Great meeting! Exposure for 3 hours and 10 minutes.
