@sergey One other place we’ve gone to while in Flagstaff was Walnut Canyon National Monument. Which is very interesting place, apparently before volcano eruption it was a home for people of Sinagua who used natural cliff walls to built houses. Of course I can’t resist to take a picture of blooming cactus.

@sergey Grand Canyon was awesome, magnificent and enormous. Though watch tower is a modern building that “fakes” as one that falling apart. There are a lot of tourists there you can hear almost any language there.

@sergey On our way to Grand Canyon we’ve stopped at Wupatki National Monument and apparently there were some prescribed forest fires, which was quite weird to see.

@sergey Second stop was Flagstaff, AZ. Central spot to lot’s of places we’ve visited. It was a great house in a neighborhood that’s trying to be a pine forest. Sky was amazing, but only thing I can do is startrails. #astropic

@sergey Our first stop was in Albuquerque, NM where we’ve spent day strolling around historical Old Town and museums. Then we’ve gone to Sandia Peak Tramway - longest aerial tram in Americas. Here is view from the top and Albuquerque at the bottom.

It’s summer time, typically for our family it’s time to explore something. We recently returned from a roadtrip across multiple states, in particular New Mexico and Arizona, with Grand Canyon being our main target of the trip. However we found lot’s of other interesting places along the way.

How would you call that? Luck? Selling stocks that would fall next day and buying stocks which would rise. Such behavior has all hallmarks of insider trading. By definition: "Insider trading is the buying or selling of a publicly traded company's stock by someone who has non-public, material information about that stock. ".

I know it's old news, but c'mon you work hard you being very diligent with your money and at the end of the day you'd have to pay highest fees?https://nypost.com/2023/04/16/how-the-us-is-subsidizing-high-risk-homebuyers-at-the-cost-of-those-with-good-credit/

Quick and lazy run down on M101, just because of all of these clouds I could not shoot anything in April, unfortunately it was 80% of the moon, not a good thing to do in a very light polluted place. But I wanted to test my new tactics so bad that I decided to do it anyway against all the odds. Here is what I've got The Pinwheel Galaxy aka M101 shot with Cannon T3i, with 135mm lens at F/2.8 and ISO 100. 1 hour of total integration time #astropic

@sergey Then upon recommendation I've tried different approach. Forget about read noise from your camera, go after more photons. As long as you are able to overcome read noise with more data you are fine. So I've tested with ISO 100 and set lens to F/2.8 and was able to put 1min and 30sec of exposure in my Bortle 7-8 sky. Results are very different, less noise, more vibrant colors. This is pic of srar trails from Ursa Major, just 15 min of integration with just bias as callibration. [2/2]

I think I finally found my trick to a better #astrophotography from my backyard. I am newbie so I've been learning a lot. Based on common knowledge you check where your camera has smallest value of a read noise and then use that ISO, which for me resulted in stopping down my F/2 to F/4 and still decreasing ISO to 800 from 1600 which i thought was optimal value, and taking only 20-25sec exposures to keep histogram just a bit above it's optimal place. Pictures were noisy, colors were mute. [1/2]

It's galaxy season, so I had to do a shot of bunch of galaxies. M87 aka Virgo Galaxy with surrounded galaxies, there are a lot of them in this shot, so I won't name each one. Shot with Canon EOS T3i, 135mm lens at F/4 and ISO 800, total integration time around 1 hour and 20 min. #astropic

@archit3ct here you can read about RESTRICT act https://www.eff.org/deeplinks/2023/04/broad-vague-restrict-act-dangerous-substitute-comprehensive-data-privacy

@thomasfuchs with changes main players doing to their engines on a daily basis any book would be outdated before it's released. As far as I know forums where people share what worked would be your best bet.

Finally clear night in a while, didn't waste a moment. Technically I wasted some time trying to get it into a frame, but it's a different story. Anyway here is M81 Bode's Galaxy, M82 Cigar Galaxy, Garland Galaxy and NGC 2976. Just one hour of integration with a really quick stacking. M81 and M82 shot with Canon T3i, 135mm at F/4 and ISO 800. Total integration time bit less than an hour. #astropic

Earlier this month we had a moment when cloud went away and you can see Jupiter and Venus really close together. Unfortunately I didn't have time to setup my gear as it was a very short lived event, so I took a photo with my phone. #astropic

@AstroAttorney Sounds like director of that documentary manufactured SVB crash just to end it with a big bang :D

That session taught how much light pollution kills astrophotography. Try navigating star-field without seeing any stars in DSLR preview, basically you make adjustments to where you think your target is, then take a test shot, rinse and repeat. Then once you are done you trying to plate-solve it to confirm that you got framing right and at that time you see like your target is already behind some object nearby. Yeah I know people designed go to mounts and so on, but manual stuff is so much fun.

I managed to shoot 2 targets(actually way more than 2) last night, problem is that not the one I planned. Here are M44 aka Beehive Cluster on one image and M46 and M47 along with Collinder 155 and Collinder 156 on another. Shot with Canon EOS T3i, 135mm lens at F/4 and ISO 800. Total integration for M44 is about 40 min, M47 is about 10 min. #astropic
