It's been frustrating lately- nearly a month of completely overcast skies. About a week ago, there was a brief period when I could try getting the Horsehead nebula. I stacked 140 0.8 s images, 400mm f/2.8 ISO 6400 and got this (cropped and downsized selection), after considerable post-processing of the stacked image:



The brightest star is Zeta Orionis. If you look carefully, you can barely see a whisper of NGC 2024 (flame nebula) on the upper left, but there is absolutely no evidence of either the Horsehead nebula or IC434, which should be near center in the image.

I'm confused about where the problem is: there are stars of +15mag clearly visible (there's a tight trio of stars in the lower right, one is 2MASS J05403667-0243469 with a R magnitude of 15.4), so I don't understand why NGC 2024 and IC434 are not visible... are they strictly NIR objects?

Any tips would be appreciated, TIA.

There's enough sunspots to measure the differential rotation rate- here's a close-up of the group on the left:

So, we have spent last week in Bieszczady, the most SE part of Poland. We had just a few hours of Sun, but other than that we had a nice winter - a lot of snow, almost no wind, and a frost - down to around -10ºC (14ºF), but not that cold for most of the time.

We were not expecting fresh snow here, but that's what we found. In some places it was half thigh high (or even half [censored]body part on the back, just above the thigh[/censored] high), but mostly just to the knee. I was breaking the trail, Marzena was following:



Have you ever wondered where does the charcoal come from? This guy makes it:



Together with lots of smoke:



As for someone living in the woods (literally: he spends weeks watching these retorts; not that he is so far from the closest village, less than an hour walk) he was surprisingly knowledgeable, we had a short, but very nice talk.

Sun was not cooperating, so even if we were surrounded by picturesque views, they all look dull on pictures:



There were just a sunny spells now and then:





Bieszczady are not high (most peaks are below 4000 ft). Some of the higher peaks are bald - which is rather unusual in other Polish mountains (apart from rocky peaks in Tatra mountains, but they are much higher). These bald parts are called "połoniny" - my dictionary translates it as mountains pastures, but I am not sure they were ever used as pastures. This flat white snow that doesn't want to have any texture is a połonina:



And finally, a picture for Andre - this is a mountain shelter called "Chatka Puchatka" - Polish for "The House at Pooh Corner", located on Połonina Wetlińska, it was about 200 meters behind my back when I took the picture above:

A composite image of Jupiter and the Galilean moons, taken as the weather permitted over the past few months. This image is about 25% of the actual size, so the patterns of the moons are harder to see, but visible enough to still be dramatic (IMO).

Since I am on a roll, check this out, no high resolution pictures this time, but I like everything about the concept.
Designed by a team of experts in sustainable design and technologies, the house showcases more than fifty environmentally friendly systems, technologies, and products, including: passive and active solar energy systems, natural, recycled and non-toxic building materials and construction, straw-bale walls, radiant flooring, permaculture landscaping, and so forth. The Center's exhibits explain all the housing model's features, including how they differ from traditional systems, their cost-effectiveness, and their payback periods. The Center, located on 55 acres of land owned by the Nickerson House Community Center, is open to the public during scheduled events.

National Geographic posts pictures of the day. I prefer the pictures taken far away from metropolitan areas, i.e., in rural or wild areas.

Here is a picture taken on the steppes of Mongolia.
