Cat’s Paw nebula – NGC 6334

NGC 6334, the Cat’s Paw nebula is a faint emission nebula on the constellation of Scorpio.

That’s finally my last capture before I get my DSLR modified for astrophotography.

My setup for astrophotography is slowly getting the way I want!

Of course, my ideia was to shot an emission nebula hard to capture with a stock camera. If everything ends right, soon I’ll post a version of this same target, with some quite similar exposure, but with an astromoded Canon T6i. Wish me luck!

Well… the Cat’s Paw nebula is a hard target for Bortle 6 skies and a stock DSLR. Almost 3 hours of exposure and I hardly got some nebulosity. I hope it will change soon, as soon my camera come back and my Optolong L-Pro arrive.

Here it is:

Cat's Paw Nebula - NGC 6334
Cat’s Paw Nebula – NGC 6334

Setup:

EXIF:

  • 87 x 120S
  • ISO 1600

My skies are getting worse

Well, when I was using my Nikon D5000, the light pollution was a problem, of course, but not a major one. I mean, I was using ISO 400, and 120s frames apear not too gray at the time.

As soon I as put my hands on my new Canon T6i, I saw the real problem. 120s subs with 1600 ISO are enough to let the frame almost white!

Look at this:

120s ISO 1600 SUB -  Cat's Paw Nebula - NGC 6334

This is one single frame with 120s of exposure time and 1600 ISO.

Optolong L-Pro Clip Filter on the way

To fix (or at least try) this issue, I bought a Optolong L-Pro Clip Filter. I’m in Brazil, and it’s coming from China, so… just imagine how long I’ll need to wait…

But don’t worry!

Canon T6i astromod on the way

Also, I just sent my new Canon T6i to be modified for astrophotography.

As you can imagine, I can’t even sleep.

As soon as I put my hands on the canon again I’ll try to shot the Cat’s Paw once more!

See you soon!

Crux and Coalsack Nebula (C99)

The Crux constellation and the Coalsack Nebula (C99) are so close to each other that we can shot it through a 135mm and a cropped APS-C sensor.

And I finally did it! Let’s see how it ended.

The Crux constellation

The Crux constellation is probably the most known constellation of the southern hemisphere, and it’s easy to understand why. There are 4 stars, being the less brighter yet on magnitude 2.75, and disposed on a “cross” shape very easy to locate.

This constellation is full of surprises. Just to the left of the star called “Mimosa” (Beta Crucis) is the Jewel Box (NGC 4755), a beautiful, bright open cluster with stars of many colors.

The star Alfa Crucis, also known as “Magellanic Star”, is the brightest one, with 0,8 mag. This is also a multiple stelar system, with at least 3 stars.

The Coalsack Nebula (C99)

I don’t know why, but I just love dark nebulas. And the Coalsack is awesome! C99 is the biggest one seeing from earth, with dimensions of 7×5 degrees! It is HUGE!

I first discovered C99 a few years back, while I was on the firsts steps with astrophotography. I pointed my D5000 to the Crux with a tripod and toke some 15s shots. When I saw this huge shadow I couldn’t believe.

The picture itself

Shot it was pretty easy, to be fair. I started just after the sunset, but the first 4 frames was lost due to the INTENSE traffic of artificial sattelites. I should have thinking on that, right?

Then I made more 96 frames of 60 seconds with my D5000 and my Nikon 135mm f2.8 at f4.

This was the result:

Crux and Coalsack Nebula (C99)

Setup:

Nikon D5000
Nikon 135mm f2.8 AIs at f4
iOptron CEM25P

Exif:

96 x 60s ISO 400

C/2020 F8 SWAN

C/2020 F8 SWAN is a comet discovered on images of the SWAN camera, aboard of the SOHO spacecraft. Although it was imaged for the first time by the SWAN camera, was Michael Matiazzo, in Australia who first noticed it.

This little guy started to gain brightness very fast, and as soon I knew about his existence, I mounted my telescope and pointed to him.

Super Moon Mosaic on May 2020

It toke more than 10 years of astrophotography so that I finally make a moon mosaic!

After a month with a lot of good nights for deep sky astrophotography (Which I’ll post here soon), the full moon came and made it unfeasible.

But my will for astrophotography stayed. What can I do?

Well, do a moon mosaic, of course!

Eta Carinae Nebula (NGC 3372) Close-Up

So, after shoting Eta Carinae Nebula (NGC 3372) with a wide angle lens, now it’s time to shot this target again, this time to inaugurate my new OTA with a close-up of those beautiful hydrogen clouds and giantic star clusters.

Not everyone knows, but Eta Carinae Nebula (NGC 3372) is four times larger than the Orion Nebula (Messier 42) and even brighter. Don’t misunderstand me. Messier 42 is incredible, but Eta Carinae is special. It is so complex, with a lot of star clusters, Hydrogen Alpha regions, dark clouds… and it’s huge! And the big red giant in its center? Speechless. This red giant totally deserves an dedicated post for its own.

Eta Carinae (NGC 3372) in wide angle

Finally, on January 7, I was able to try my “new” old Nikkor 135mm f2.8 AI, that promises to be a great wide angle lens. I chose as a target Eta Carinae Nebula, or NGC 3372.

This nebula is one of the most beloved targets of the south hemisphere. It is located on the Carina constellation, and just the main nebula itself (NGC 3372) have 2 degrees of aparent size. It is huuuuuge!

Moon and Saturn conjunction on November 29

Moon and Saturn went on a beautiful conjunction on November 29, 2019. And I was able to register, because…

It’s Friday, Friday… gotta get down on Friday!

Ups, sorry! Got carried away.

Well, my first successful high dynamic range of the moon.
