Perigee Moon – February 19, 2019

Posted in ASTRO on February 20, 2019 by maxpho

A wonderful Moon at perigee. Big, bright, and steady; that is, in good seeing conditions.

Equipment: 200mm Newtonian, Baader MPCC, ASI1600MMC, Baader RGB filters, Baader IR-pass filter for luminance.



And a smaller version:



High resolution lunar images – February 17, 2019

Posted in ASTRO on February 18, 2019 by maxpho

An annoying session, with highly variable seeing conditions. I did try to get the best of the images, but I think I’m loosing my touch (I haven’t imaged the Moon in high res for some time…).

Equipment: 355mm F/4.5 Newtonian. ASI174MM, red filter.

First Quarter Moon in colors- February 13, 2019

Posted in ASTRO on February 15, 2019 by maxpho

The result of a short imaging session with the Moon, in mediocre seeing conditions. I did try to get the best out of it, with soft colors added after intense processing. Too bad the seeing was on the poor side…The image is with South up, as seen through the eyepiece.


The Moon with Saturn – February 2, 2019

Posted in ASTRO on February 2, 2019 by maxpho

It could have been a wonderful event this Moon-over-Saturn event, but the Earth’s atmosphere said otherwise.

Lots of cirrus clouds rolled in…At least they’ve showed their true colors at sunrise…

I did manage to catch the pair while rising, between some trees…

A Moon with colors – January 15, 2019

Posted in ASTRO on January 24, 2019 by maxpho

The result of a short session with the Moon at minus 7 Celsius, on the shores of the Arges river. The subtle colors were revealed after intense processing of the three color channels.

The scope was a 127mm Maksutov telescope, while the camera was the ASI1600MMC with RGB filters. Poor seeing and lots of fog (the Moon was the only visible object in the sky, with maybe 3 or 4 stars).



Total Lunar Eclipse – January 21, 2019

Posted in ASTRO on January 21, 2019 by maxpho

A wonderful astro event.

Had to drive for a while to find a clear sky location, and while the local temperature went from -4 to -7 Celsius, the only annoying factor was the fog. Despite these factors, the eclipse looked wonderful, with a low contrast Moon (mostly due to the fog) hanging above the horizon. On the opposite side of the eclipse another nice event was occurring: the conjunction of Venus and Jupiter.

My gear: Canon 6D with Canon 70-200 f/4 L lens, and Canon 550D on a 115mm F/7 APO Refractor.

Colors of the Moon – January 17, 2019

Posted in ASTRO on January 18, 2019 by maxpho

A colorful image of a quadrant of the Moon, showing different mineral concentrations at the lunar surface.

200mm F/5 Newtonian, 2X Barlow lens, ASI 1600MMC Pro, Baader RGB filters. 500 out of 1500 frames for each filter.



A Moon mosaic made up of 33 images. This image required about 2 hours of work in order to be saved: the local conditions (fog, cirrus clouds, variable seeing) influenced about 30% of the images that make up the mosaic, so a lot of post-processing was necessary to normalize the individual areas. This is the reason why the image was resized to 50% from original. Also some details on the terminator had to be buried in the shadows due to the varying conditions..:(
