I'm having difficulty understanding from Astrogear's website which astro-mod I should go for with my Sony Alpha7R. As far as I can tell, it would make sense to choose the first option (UV/IR blocking bluish filter removal only), and pair it with this Astronomik clip-in light pollution filter. However, the combined cost of the mod and the filter is $400, which is $50 more expensive than mod #2 (Enhanced Spectrum Conversion with Optolong Luminance Filter). Is the drawback of option #2 that the Optolong filter is a permanent installation and can never be swapped out for any other type of filter (like a Ha-filter) in the future? I can't quite figure out why they refer to #1 as the less expensive version if you are inevitably going to pair it with a filter of some type.

thinking about possibly buying some stuff for the eclipse. anyone have a reputable source for glasses? using amazon for something like this kinda wigs me out. also contemplating a solar filter for my 6" dob (skywatcher i think)

Hi astro friends. One of my oldest friends just died suddenly after a short illness. He was an astro and landscape photographer, starting his job as a hobby taking photos of the Perseid meteor shower from the beach in Turkey where we spent every summer, before managing to turn it into a full-time job and travelling the world with it, eventually writing the magnum opus of astrophotography "photographing the night sky".













He leaves behind a wealth of gorgeous art, as well as an informative and inspirational YouTube page with a wealth of videos on how to photograph all sorts of astronomical phenomena. I'm gonna leave some links here because maybe his work can be helpful for some of you as it was for thousands of others.

Well, silly me, I should have expected that he'd already be known in these parts. It's some consolation to his parents, at least, to see the thousands of comments from people who he inspired or helped in the astro community.

A good and also wild soul that lived more in his short years than most would with 100. His persona in his astro videos always amused me because he comes across so gentle and softly spoken, which he could be, but most of the time I knew him we were getting up to all sorts of silly poo poo.

He was an amazing photographer and sounds like a great guy.

I'll paraphrase what John Dobson told me after I met him at his 90th birthday party: If you want to do something to remember him by, find a place to set up a telescope if you can, and encourage people to look at the sky.

Good luck to all of you chasing the eclipse. I have my ten-inch Dobsonian telescope packed in my back seat, a cooler, drawing pad and tackle box, and a whole lot of hope things work out for viewing.

Didn't think I'd be diverting from Erie, Pennsylvania to Akron, Ohio, but here we go.

I have three scopes at the helm for today. I'm only going to see 97% coverage or so from home, but I didn't want to join the masses and traffic. gently caress that noise.

Seestar s50 for a time lapse video, 8SE for regular photos and a 10" dob for viewing - all with proper solar filters..yadda, yadda, yadda.

Sidenote: I wonder how many idiots are going to damage their eyes with knock-off viewing glasses. Seems there's a lot of fakes and counterfeits on the market. A new discount store opened near me called "Insane Deals" and they have been selling the glasses for 99 cents. Someone posted one online and it was a clear counterfeit. It may work or it may not. For their sake I hope Chinese quality control existed for these counterfeits.

i doubt there's too many eclipse glasses that will blind people on the market. the no-name chinese version from amazon was fine last year, it was fine in 2017, and i see no reason that it wouldn't be fine today.

it's hard to even know what you mean by 'conterfeit eclipse glasses.' they are not generally brand-name items, and i can't really see places biting on baader/celestron/whoever's name. they're pretty easy to make, too, so it's not like there are a ton of corners to be cut in the first place

A lot of the eclipse glasses are made by American Paper Optics in Tennessee for a variety of brands including those sold by Explore Scientific. The Chinese counterfeits list APO is the company of manufacturer, but the tell is they lack the address, country of manufacturer and bar code. Those counterfeits are suppose to be okay, but need to be checked individually.

However, then there's the fakes which have showed up in the streets on NYC and elsewhere under the Qiwei manufacturer. These are the potentially dangerous ones as they did indeed cheap out on the materials and it's like looking through a pair of sunglasses opposed to the good material that blocks out everything except enough light to see the sun. The American Astronomical Society has details on their website about it.

We're only getting something like 30ish % today, but I made the journey to the desert of Idaho for 2017 which I'll remember forever.

Looks like for Aug 2044 I won't have to go anywhere for totality, here's hoping I'm still on the right side of the dirt.

I'm directly in the path of totality so i'm hoping the clouds hold out! Lot of Cirrus clouds but nothing else so far, so here's hoping i'm able to get some decent photos! Good news is I'll be able to just walk out in my driveway and see it so I don't have to lug my stuff very far :v:

This is why my plan was to get to Erie Akron as early as possible and leave for home at like 8 pm. 97% is too close to miss out on it.

i only had about 50% coverage at peak, but as i was looking at it through my telescope, a passenger plane crossed the sun's disk

so that was probably the rarest event i'll ever see in my life. i just happened to be looking down at the time instead of playing with my phone's camera or something. very cool to have seen something like that.

This is what you get at 97% with the SeeStar. Better than a kick to the head. I'll have to check to see what the Olympus TG-6 did on the 8SE.

Obviously it's too late to give advice but if you were at the 97% region you really shoulda made the effort to get to 100%. The experience is completely different.

I wish I could have, but the kids has testing today and wife had to work. I was homebound without other options. It is what it is. Actually, I'm happier that it was actually fricking clear last night and not brutally cold. I was able to start viewing galaxies again with my own eyes with the 16" dob. Tis the season.

We were supposed to be 60-80% cloud covered in my suburb south of Cleveland and instead got a virtually perfect sky. I got over 1800 images With my Seestar in my time lapse, but I'll share these last two shots. So happy with this little scope.

I have more to post when I get back home to Pittsburgh. One of our telescopes had a hydrogen-alpha eyepiece for looking at the surface of the sun. I'm confident that the middle prominence is the one that stuck out during totality. We figure it was two or three Earth-diameters in length.

Down came the glitches and burned us in ditches and we slept after eating our dead.
Just wanted to share the photo we got somewhere. Handheld camera shot of some sort during totality. Crossposting from space thread.


First eclipse, insane experience, glad I traveled six hours and climbed a mountain to see it.

Being able to see that solar flare with my bare eyes was insane, I never imaged such a thing would be possible. I really enjoyed the insane banding effect all over the snow landscape right after totality as well.

Shameless share from 2017. I wasn't able to make it to totality this year, so didn't bother busting out the equipment for 85%. 2017 eclipse is still one of the coolest experiences of my life.

They’re called shadow bands and we don’t really know. The leading theory is that it’s caused by the atmosphere.

It seemed to me like faint clouds. I could only see them very close to totality. I figured in other circumstances it was too bright to see them.

They are pretty low contrast so it seems reasonable that we're unable to see them with too much sun. I don't think they've ever been reported on an annular.

A total eclipse with a blanket of snow seems the most reliable.

Luneshot

Shadow bands are because the nearly-eclipsed sun is just a pinpoint source getting refracted through the turbulence of the atmosphere. It’s the same concept as atmospheric seeing or stars twinkling; the smaller the angular diameter of the light source, there’s less apparent area to average out the variations.

Has anyone found any stupid high res shots of the eclipse? I want to use one as a desktop background.
I traveled to Erie for the eclipse. Totality was amazing, the drive home sucked (7.5 hrs). My wife said it was a lot of effort for 3 minutes, I told her that's the story of my life.
