The prediction was right and the repos were really handsome for about 5 minutes half an hour before midnight.

For several years, I have been trying to get the “flames” of the Cigar Galaxy photographed without success, so I decided to point my brand new telescope with the HO filter at the Otava Bucket area. For two consecutive nights (March 14th and March 15th), I collected a total of just over 9 hours (76 x 450s) of exposure, and even though the moon shone quite bright, I finally got to see the flames! The end result is surprisingly accurate, so the air must have been calmer than usual.

Last night there was quite a bit of wind, so the telescope had to be positioned in terms of airflow to the quietest corner of the house. However, only the northern sky was visible from this. I decided to test the functionality of the shooting equipment I adjusted for a moderately challenging object, the IC 342, otherwise known as the Hidden Galaxy, which is located quite close to the Milky Way belt and thus has quite a few stars and hydrogen clouds in front of the object. I got a pile of 6½ hours of exposure, which makes the subject stand out quite clearly in the picture. https://astrob.in/6q5...

It has become a tradition to photograph the Swan at the beginning of the season. This time with the help of the country-famous ASIAIR Pro, which makes the life of an astrographer much easier. Next, the focus will be on depicting NGC6888 at the bottom of the image with a larger tube.

In addition to the hunting trip to Inari, I also have time to photograph space. In the background of the tent is the Milky Way, the Andromeda Galaxy, and a calm northern lights belt that eventually evolved to cover up behind the Milky Way mists.

While waiting for a suitable cloud gap, that comet moved to a favorable position, and with the 250-millimeter wide-angle tube, in addition to the comet, I got a couple of dense stars and one of the most handsome nebulae in the northern sky - Heart Nebula. The idea was to take as many short exposures as possible (25 seconds) to get a timelapse video of the comet’s motion. However, the movement of the comet was so small that the end result was not worth the publication. Admittedly, due to the glow of the almost full moon, it was not worth taking longer exposures, and after stacking just over 500...

The new field of view of the RedCat51 telescope is just a passel to capture this very large emissions fog. The exposure accumulated for a total of almost 3 hours, which was great enough to capture this moderately bright subject. On previous shots, an unfortunate number of underexposures were out of focus, so I decided to adjust and lubricate the Skyguider’s wheel. This was clearly beneficial, as now all the exposures were excellent. In the post-editing of the final image, I gave myself a bit of artistic freedom and thus the end result is a bit "unorthodox" in terms of colors;)

Thanks to a rare good shooting night, I got a record 5 hours of exposure from this handsome subject in the Swan Tail area. The new RedCat51 lens starts to show its nails when focusing, polar aiming and tracking are noisy. Setting up the set to full shooting condition only takes a quarter, which is a good thing for future winter shooting sessions.

On the merits of a clear night, I was able to test the new shooting set again. This time I moved the stand from the grass to the hard ground and the tracking improved considerably. That is, the grass gave up so much that the polar sight shifted according to the focus of the shooting head. MGEN worked great until the clouds came to disturb after a couple of hours of exposure. For some reason, the guider did not survive this, but after the clouds disappeared, the shot was not completely sharp for many. Eventually I got 50 piles of 180 second exposures at ISO800. The subject is so bright that thi...

Finally and finally the astronomical twilight has reached the Arctic Circle and last night was a couple of hours of favorable conditions for the initial testing of the new optics. In the summer, William Optics' pretty red 250mm f / 4.9 RedCat lens and color-matching tracking engine and Red Dot were used. Because in Lapland, the sun shines day and night for half a year, and for the rest of the time there are either clouds, ice fog or northern lights interfering with the shooting, so attention will be paid to the appearance of the equipment when nothing else can;) The target is the classic d...

There was a really clear sky for a while this morning, so I captured quality photons. After quite an adjustment, my best sun image so far was born :)

Home Office Day makes it possible to combine work and hobby. In the morning there was a moment of clear skies and only a faint cloud of gauze in front of the sun. Through the association’s solar tube, I separately took videos of 1,500 images from the surface and perimeter of the sun, of which I stacked 150 images together and combined them into the attached image.

After the tripod was serviced, I finally got to test its operation and while waiting for the sky to darken, it was a good time to shoot the moon. I took 250 pictures, the best 50 of which I stacked in the picture below. The end result is intentionally slightly pulled over to make the dimmer surfaces of the moon more visible.

On a ski vacation came the deep space described in the evening when the sky was clear. Here’s a 50-minute exposure with a 200mm lens from my favorite subjects Heart and Soul Nebula.

You can also take astrophotos on a ski holiday! I set up the camera in the yard of the rental cottage and aimed a 200-millimeter lens towards the Driver's constellation. The comet Iwamoto cools down in space so fast (230,000 km / h relative to the ground) that I stacked just over 20 minutes of exposure in the image below. The picture also shows nicely e.g. Flaming Star Nebula and the open constellations Messier 36 and 38.

Orion is only visible for a couple of hours at my backyard location, and even then the light pollution in the city is just right on the road. As a result, I have done little to describe the handsome objects in that area. I had just maintained the tripod and wanted to try it out without a guide. I exposed the Horsehead Fog for an hour and although there was a lot of missing from the subject due to light pollution, the main thing was described handsomely.

A few weeks ago, I was able to fit an image of the entire Driver’s constellation with an 85-millimeter lens when I first tested my new Canon 6D. Now I decided to try my luck with a 464mm telescope in the mists of the Driver Center. I got a 2-hour exposure, which I brought to life with more powerful image processing than usual. But these "native" of the miracle of space are not very strange.

Due to the location of my shooting location (backyard in a detached house area), light pollution in the city effectively prevents south-facing shooting. However, Orion is now so high that when the constellation was in a suitable south-facing direction for a while in the evening, I was exposed to the object for more than half an hour before it was left behind the houses. But since the subject is very bright, the exposure was sufficient. Messier 42 is also an interesting object in the sense that in 1880 the pioneer of astrophotography, Henry Draper, produced the first deep-sky photograph of mank...

The saying of the old people, " Keli is the one who pulls the load," is also true in astrography. If the weather is favorable, then taking a good picture will be easier. The whole day was clear and I had adjusted the equipment to the backyard in good time for shooting. The clear dark sky lasted four hours, which was great enough to expose this subject. The hardware also worked well. Since it was known that the material was of high quality, I correctly took all possible corrections. With PixInsight, I did stacking, color correction, background balancing, and noise reduction. In Lightroom I made...
