M42 Orion Nebula

Temperatures as low as -6°C, clear sky but still average seeing. Visual observations of M1, M42, M45, M78, M79, M81, M82. Around 22h00 meteor at 15° above the horizon and in the south East moving in the direction of the south. Photographs made of M1, M42 and IC434.

Misty Weather

Even the fact I can see some stars, the sky is covered with mist. The street lights reflect the light due to the small droplets so badly that it is not possible to make any observations.

The sun today - PST comparison with SDO data

Clear skies so time to observe the sun with PST 40. One big prominence at 11h and smaller ones at 4h and 9h. I made a comparison with data from SDO and the result is shown below. I must say that the comparison is very good. My picture was made afocal using a 8-24mm zoomlens and edited using CS4.

No sunspots but bright sundogs

No sunspots today but due to low and high clouds it was ideal for observing some bright sundogs.

Happy Birthday : 4 Year blogging

Celebrating 4 year of blogging ... started on December 23, 2012

Solargraph Failed due to overexposure.

As mentioned earlier, one pinhole camera disappeared a month ago and yesterday I found out that after 6 months exposure my other one did not show much details.
Bad luck but what can we learn from this?
My conclusion of the latter is that the paper was overexposed. This probably because the can (this time a used a piece of a "sewer pipe") wasn't light prove, so the sun could penetrate through the can and did expose the paper.  Instead of exposing the paper via the pinhole.
