One halo form

A nice 22 degree tire was visible from the backyard.

I browsed through the summer photos and found a previously inconspicuous detail in a halo photo. There is another ring inside the 22 degree ring. I interpreted it as an 18 degree ring.

I chatted with neighbors in the yard when I saw a bright 22 degree tire. I went to the grocery store and the phenomenon was visible throughout the trip between dimming and brightening again. No other halo forms appeared throughout.

Several bright halo forms

In addition to 43 species, a few halo phenomena were spotted during the birding trip.

The shopping trip showed a nice 22r. The sun was convenient to cover with the church tower.

In the English-speaking countries, the fog area known as Running Man Nebula, just north of the Orion fog, was aptly described and I seized the opportunity. After all, there is also an open constellation in the area of the destination.

NGC 1275

The active elliptical galaxy NGC 1275 in the constellation of Perseus does not particularly capture attention in this image. The target belongs to the Perseus galaxy cluster, several other members of which are shown in this figure, such as NGC 1272 and NGC 1278. Compared to how close we are to the level of our own Milky Way, there are downright staggering galaxies.

NGC 6946

This spectacular top-view spiral galaxy was filmed on the first night of the Club and Association Action Seminar. The object, which was previously revealed to be handsome in the grayscale image, was definitely worth photographing in color as well. The densities of the branches and the areas of ionized hydrogen also emerged better than less than a month earlier.

NGC 7814

This side-facing item on the Caldwell list is sometimes known as Little Sombrero. The shooting night was mostly very good, but still when photographing this subject, gradients appeared in some individual frames that are difficult to explain with anything other than subtle cloud cover. However, I managed to clean them reasonably.

(159402) The 1999 AP10 Amor / NEO asteroid was filmed on the first night of the October 2020 Virtual Club Event. The asteroid was discovered by the LINEAR Socorro exploration program on January 14, 1999. The total estimate of the asteroid is 2.1km and the rotational speed is 7.908h / r. Spectral class estimated S (stone). We have been filming this Cupid already in September and October. When photographing the asteroid was 0.0817au at a distance and will be closest on October 19, 2020 to 0.0806au. 1Picture. first image measured, 2020-10-16T 19: 20: 33UT 2459139.30593JDUT 22h15m30.58s + 40d18...

This spectacular Seyfert galaxy is one of William Herschel’s discoveries, and it’s no wonder the object ends up on Caldwell’s list as well. The open spiral structure stood out nicely even though the apparent size of the object remains small. The asteroid (33092) 1997 YR1 was also found in the same field of view.

(33092) 1997 YR1

(33092) 1997 YR1 (1997 YR1,1999 LN26) The asteroid on the outer edge of the main zone was photographed on the first night of the October 2020 Virtual Club Event. When photographing the ace galaxy NGC 7479, this came into the picture. The asteroid of the Mitidika family was discovered by the Chinese SCAP (Beijing Schmidt CCD Asteroid Program) at the Xinglong Observatory (code 327) on December 20, 1997. The size of the asteroid is 7.72km. Spectral class presumably C, based on family. When photographed, the asteroid was 1,823au apart and was closest on September 11, 2020 to 1,661au. 1Picture. fir...

The dolphin has two spherical constellations worth photographing, of which NGC 6934 is brighter in light of statistics and this dimmer. On the other hand, the object now described seemed more concise. I lined display so that the scale is the same as previously NGC 6934 to ottamassani FIG .

M2

On the opening night of the Club Seminary, we waited impatiently for the final recession of the clouds. It wasn’t yet time to shoot the dim subjects, but the bright spherical set at almost zero declination came out of the clouds perfectly and even surprisingly close. Admittedly, some of the exposures flew into the trash when stacked by clouds.

The star rock sky began to be dark enough to capture but the clarification still allowed itself to await. Immediately after taking the new and apparently successful flattened squares, I decided to point the telescope at the spherical set near the tail of Pegasus. The subject revealed its character very nicely, although some of the exposures were eventually unusable due to the clouds.

Several halo forms

There had been clouds in the sky, but not really halos at all. Next to the Koskela fortification area, we noticed a weak halo ring on the left. The picture also shows a possible section of the pillar.

Sun

I visited the Kaivopuisto observatory for a long time inside the cough trio and had to head for the tower. At first, nothing was visible, but then a flare eruption appeared. It was fun to follow its development. So that the protujaki was visible, but no wonder. I got one lousy picture. Others are worse than this.

The side sun was visible at 9:40 in the morning, but there are only 22 and 46 degree tires in this observation. I can’t determine if it was 46r or 46ys when it was such a short clip and quite dim yet. Let the Skywardens draw their own conclusions.

On a business trip haloth. 22 degree ring and its upper sidewall. Picture of the brightest stage. I used to also look to the opposite side of the sky in the hope of rarities, but again there was nothing there.

One halo form

A faint partial 22-degree tire photographed from a workplace window.
