Two comets – October 5, 2018

Posted in ASTRO, Uncategorized on October 6, 2018 by maxpho

One of the following two images shows an object that might become visible to the naked eye later this year. That object is the periodic comet 46P/Wirtanen. For now, the comet is heading south, and it is still rather faint, especially when observed from the northern hemisphere, as it is close to the horizon.

The second image shows another periodic comet, 64P, which has a similar magnitude these days. Due to the very different positions in the sky, (with 64P gliding in Andromeda, close to the zenith), 64P looks a bit brighter and larger compared to 46P, but they are actually similar in magnitude. Both comets show elongated comas.

Mars – August 15, 2018

Posted in Uncategorized on August 16, 2018 by maxpho

Another imaging session with the Red planet, in mostly stable seeing conditions. Too bad the low altitude of the planet does not allow for finer details to get through the Earth atmosphere. The next opposition (in 2020) should however be much more interesting…

For now, almost one hour of Mars, shown as the planet rotates and the image is affected by the atmospheric turbulence. 355mm Newton, ASI 174MM, IR pass filter (>685nm).

Some old shots of…insects, reptiles…and others.

From 2013/15, reprocessed in 2018.

A few insect eggs

Posted in Uncategorized on June 8, 2018 by maxpho

I’m searching some images on my old drives, and somehow I’ve stumbled upon a few very old dusty (with some dust on the sensor that is) shots of insect eggs. They are pretty interesting…

Eudia pavoniella – March 2, 2018

Posted in Canaraua Fetii, Evenimente, Experimente, Specii rare, Uncategorized on March 2, 2018 by maxpho

Spring is coming, and the first sign was observed in my balcony where I keep a few cocoons of a lovely medium-sized moth. A single female emerged today from one such cocoon. The species name is Saturnia pavoniella (Scopoli, 1763), a moth occurring in Europe. In Romania, I’ve found it in three locations already, in almost all the evolution stages: eggs. caterpillars and more recently as adults. It frequently comes to light during the colder nights of March-April, and sometimes in May, depending on altitude.

This species is not yet threatened, but it seems that its range is changing in recent years.

Also, the male. The following shots are of a freshly emerged male from March 10.

The Moon after Space-X

Just a Sunday joke…for lunar and SpaceX enthusiasts.

Not something I wouldn’t like to see or do one day…

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:
