Sunrise on Mare Crisium

[Bernoulli]

Time for another moon and, maybe if the spring rains are done, more moon pictures.

Here's through a 4" apo refractor at f/9 (900 mm) into a 50D for 1/15 sec, ISO 100. And very little processing for me.

We saw images of the "Lunar X" from someone else here last month. Maybe we can call this the "C of Crises"! OK, it's not that funny.

You can see the frozen lava ridges stretching across the mare. These are the remains of successive lava floods across what started as a VERY large crater. The last flood was about the time life arose on Earth.

Clear skies everyone!

oh my gosh..that's beautiful! Great job!

Lovely image mate. It feels like you are on one of the Apollo missions in orbit just prior to landing.

Baz.

[grfics]

I like it! Good 3-dimensionality on the crater edges and yes, the lava flows. Very nice.

[Celestron]

Yes I agree also Great shot , detail excellent !

[Bernoulli]

Here's one of my favorite focusing targets. These twins are Messier A and B, and they were made by an asteroid coming in from the East that hit at a very shallow angle. It skipped once, buried itself in the ground, and sprayed debris out to the west.

4 inch apo refractor, 2X Barlow lens gives 1800 mm, 50D, 1/30 sec, ISO 100.

[Celestron]

I like that shot Bernoulli !

And here's Mare Crisium with a little more sun on it.

I've shot the moon through lots of scopes, but it's hard to beat a long-focal length 4" apo refractor. Any scattered light in the optics just kills your lunar pictures, and these just don't have much of that.

[Bernoulli]

And, last one tonight, a long exposure.

15 sec at ISO 400

[bht-kevin]

Incredible pictures!

[tt_mt6]

Nice!

[Nighthound]

All are fantastic images.

I was scanning your high mag shots for domes but didn't see any. They're fun to hunt for and easiest to resolve near the terminator. Keep 'em coming, excellent work as always.

Now that you mention it, I did get a couple. I didn't think to look till I saw your post. They are just left of center in this image. That's Tau Cauchy on the left and Omega Cauchy on the right. You can barely see the little summit pit on the top of Omega.

You can also see them at the very top-left of the Messier image I posted above.

If there were such a thing as "Astro Porn," the OP would definately qualify...

Thanks! I know there is "gun porn" because I'm Bernoulli in the GlockTalk forum and there are several excellent photographers over there. I guess there must also be "airplane porn" as well.

[canonnoob]

crazy weather lately huh? down here in springfield MO weve been getting everything that you all have.. great shot!

[FlyingPhotog]

Indeed there is...

I'm a prime purveyor! :cool:

Here's a regional view.

[Bernoulli]

Here's the boundary between the Sea of Serenity (above) and Sea of Tranquility (below). You can see a clear boundary where old lava was over-run by newer lava. Apollo 17 landed in that clump of mountains with the dark floor, just upper-right of center.

This is 1800 mm through a 4" refractor, and that's about all the power I dare do. I made a composite of the entire moon from tonight at this resolution, and it's 70M!

[Bernoulli]

Mountains and shadows.

[Celestron]

Bernoulli those a re fantastic upclose shots !! I really like this type shots !

[Bernoulli]

Thanks Ron. I just got this 4" refractor and I've never gotten moon shots so good. It beats my 6" Mak and my 8" SC by miles, mainly due to the lack of scattered light.

But I can't take credit for Baz's great shots! ;)

OH SORRY !! :oops: . I was thinking Baz .

So what scope didi you get ???

[Bernoulli]

I consider it a compliment!

I got an Orion 100 ED. 4" diameter, 900 mm. No discernible color on the moon. Very very sharp contrasty images but, with only 4 inches of aperture, it gets a bit dim at high magnification.

I have a question over in the "how to" section if anyone would care to clear up the mysteries of the Barlow lens for me. It's at:

[MidnightSun]

Beaut......:D

[Gridlock]

celestial porn indeed, very nice :)

i think i need to look into this some more, i love taking pictures of the moon and the sky, but have never had anything that good :)

[Bernoulli]

celestial porn indeed, very nice :)

Wait till I tell Mom that I'm a pornographer!

Last night I hooked up the 4" refractor and the Barlow to get a FL of 3000 mm and shot a mosaic. It took four fields to cover the Moon and I took five shots of each. First, I stacked the five of each field to lower noise, then I photomerged the four stacked images into one. I ended up with a monster image (97 MB) of the entire moon at the resolutions of the earlier images in this thread. Lots of detail.

Now, it's pretty heavily oversampled for the telescope's resolution and that's most of why it's so big. The disk is about 6000 pixels across! One interesting note, sharpening gave absolutely no improvement at all, so it must about as sharp as the resolution will allow. I'm still playing with color cast and curves, trying to make it look real but not washed out.

So here's the vastly downsampled version. I might make a great big poster out of the original for my office.

Comments and criticisms are welcome!

[legoman_iac]

Not sure if anyone's asked this already ... but is Bernoulli based on Earth? I can't help but wonder if he's stationed somewhere overhead, orbiting us, while popping off these shots ... they're FANTASTIC!

[Jeff]

That first one is very, very nice. Kinda surreal.

[Bernoulli]

Wow . . . this has to be the oldest thread resurrection. I barely remember it. Thanks for the memories!

[legoman_iac]

No ... thank you for the cool pics, I'm almost, nearly about to buy my first scope and this forum has been a great inspiration and help! Am sure I'll be posting a squillion questions shortly.

[Rnauman821]

All your photos are stunning.

[ejicon]

so much detail in each picture. I know I've seen many pictures of the moon... but gosh. these are epic.

[airbutchie]

WOOF!! Great capture Bernoulli...

- airbutchie :)

[67champ]

VERY Very nice! OK, so we have an "X", a "V", lots of "O's, and now a "C".... :-)
