Three buckets were spending time in the club on Tuesday night, and the sun could be watched and observed in many different ways; visually with a telescope (Astrosolar film in use!), digiscoping, a planetary camera, and otherwise just admiring the landscape after the sun has already set below the horizon. Initially, more detailed images of sunspot groups (2978 and 2975 & 2976 [of which also separate images]). 5. in the picture ‘digested’ The sun near the horizon at 20:10. Figure 6 The Pillar of the Sun could have had its own separate observation, but let us also add in this context --- Spring i...

I decided to go to Ulvila's Palus beach to calm down after a busy Christmas Eve. Previously, the values had been good during the day, they decreased towards the evening, but there was a dim arc for the eyes, but now my camera was able to pick something out of it.

One halo form

I’m not even sure if this is the halo of the moon, but I myself haven’t seen a similar (perfect circle) around the moon. The pictures are bad because it is difficult to get a sharp picture of a ship moving by hand The first picture with a cell phone and the other two with a wit.

The first shooting target of 2023 is the Boden and Cigar galaxies. in the picture also NGC 3077. the intention was to get a little more out of m81 Spiral Galaxy than in my previous attempt, but still had to wait. The moon on the night of the shoot was about 77-78 percent three slightly different versions

Petteri Ahonen, Porin Karhunvartijat

Learning how to use the new tracking stand and telescope. target Seulaset or the Pleiades. The filming location is Merikarvia, the Kräsoora bridge hide, an EXCELLENT place to spot. These areas generally have quite a lot of extra light, but this is a good place. Light pollution from Närpiö in the northern sky, but otherwise the sky is open 360 degrees and perhaps the darkest Kolkka that I know in the Satakunta region. Strong recommendation! the starry sky looked amazing last night. Eqm-35, Skywatcher 150 pds, Nikon d7200 19x60s, 20x60s darks

After a short cloudy period, I finally got to photograph the Orion Nebula. The exposure was only 26 minutes in total, as I remember, but it was great to be able to shoot even for a moment.
