Heart and Soul Nebulae – December 26, 2017

Posted in Uncategorized on December 27, 2017 by maxpho

One more test of a deep-sky imaging setup to be used in H-alpha light. This time it was the 100mm Canon Macro lens that I’ve decided to use. Too bad that at f/4.5 it is still pretty bad, with comet-like stars visible in 1/3 of the frame. But somehow, the final image looks nice in my eyes due to the very similar results I’ve got early in this hobby, back in 1997-1997 with Zenit cameras on film. Memories…

Setup/Exposure:

Canon 100mm lens at F/4.5, ZWO ASI 1600MM, Baader 7nm H-alpha filter, NEQ 6 mount, guiding with 200mm lens and Meade DSI I using PHD2 software. Sensor temperature +7 C.

6×600 sec exposures, with 50% gamma and Gain 100. Only one dark acquired. Sky conditions: some fog, cirrus clouds, Moon one day after First Quarter, -2 degrees Celsius.

First, the colorized version:

And the Black-n-White version:

Sunspot group 2665 – July 11, 2017

Posted in ASTRO, Uncategorized on July 11, 2017 by maxpho

After some time (ages actually) of “astro-inactivity” I’m slowly trying to get back at it…

After the lucky ISS transit in the morning, I’ve spared two hours for some solar imaging. A lovely giant was present on the Sun, so a few quick shots were obligatory 🙂

The setup: TS APO 114mm, F/7, with the ASI 174MM camera. The Herschel wedge for White Light, and the Quark Chromosphere for H-alpha. Good seeing.

A comparison shot:

The White Light:

ISS and a sunspot

Posted in ASTRO, Uncategorized on July 11, 2017 by maxpho

A lucky transit of the ISS occurred over my home. Only a fast setup of the astro gear was required for this event.

The large AR 2665 sunspot group added the already interesting view.

Equipment: 127mm Maksutov, full aperture solar filter, H-alpha 35nm filter, ASI 174 MM camera.

Sombrero Galaxy – March 28, 2017

Posted in Uncategorized on March 31, 2017 by maxpho

One image of a superb edge-on galaxy: Messier 104, or better known as the Sombrero-hat galaxy” (“Sombrero” for short).

This image was exquisitely hard to acquire and process due to the low altitude of the object, lots of light pollution, bad seeing, and some wind. The image was acquired with the 355mm F/4.5 Newtonian, Baader MPCC, ASI 1600MM with no filters. 1500 frames, each a 3 seconds exposure.

Comet 2P/Encke and planet Venus

Posted in ASTRO, Uncategorized on March 2, 2017 by maxpho

Another astro-session and another comet. This time it was comet Encke that got my attention. Despite being rather low above the horizon in the sunset skies, the coma of the comet was well captured. The poor local transparency barely allowed me to catch a glimpse of the faint tail.

The second object of the session, planet Venus, was greatly disturbed by the poor seeing. Yet, the Moon-like appearance was captured using the 4.5 inch refractor:

Star Trails at Runcu Stone – January 1, 2017

Posted in ASTRO, Uncategorized on January 2, 2017 by maxpho

A first post on this blog for 2017: a long 2-hour exposure acquired by my wife during one of our trips to Runcu Stone (Dambovita County), on the first of January 2017. She used a Canon 550D at ISO 3200 and 1 minute long subs, with a Samyang 8mm fisheye lens, all on a small tripod. I’ve only did the processing. The intense light pollution at lower right comes from the city of Sinaia.

ASI 1600 MM – First light

Posted in Uncategorized on December 24, 2016 by maxpho

Santa was good with me this year again, and gave me a new astro-camera: the ASI 1600MM.

However, the First Light shots were acquired in poor conditions, with lots of fog and low temperatures (-5 Celsius).

The main subject was comet 45P Honda-Mrkos-Pajdusakova, which for now sits very low above the South-Western horizon. An elongated coma and a ghost tail may be glimpsed in the following shot.

And since this was first light, I’ve also decided to image the “Double Cluster”:

This small-format, 16 Megapixels camera will surely be put to serious testing the following weeks 😉
