Penumbral Lunar Eclipse Imaging Session - September 17, 2016

The sky this early morning was cooperative for me to document the September 17, 2016 Penumbral Lunar Eclipse from start till end with clouds mostly passing beside the Moon. I went to fellow ALPer Andrew Ian Chan's residence around midnight and meet him at the roof deck. I used a very basic setup to image the event using a Canon EOS 500D DSLR with Canon EF 100-400mm f/4.5-5.6 IS L lens mounted on a sturdy fluid video tripod. The sky was slightly hazy at the start and also shows a huge 22 degree Moon Halo which worries me a bit as it is a sign that bad weather is coming in a day or two. As the eclipse progresses, the haze thinned out and let both of them get a good view of the penumbral lunar eclipse specially at maximum eclipse which shows a 91% shading at around 02:54am Philippine Standard Time (PST). PST is +8 GMT. The event ended at around 04:50am PST and I packed up and went home. It was very tiring but fruitful session. Thanks to fellow ALPer Andrew Ian Chan for the accommodation and patience to stay with me till end of event.

Solar Imaging Session - September 11, 2016

The sky this morning is clear but seeing condition is fair. AR2585 Sunspot Group is starting to deteriorate while AR2589 Sunspot Group is starting to grow a bit. The huge dark filament that is on the limb also produces a beautiful Filaprom visible on the western limb.

Solar Imaging Session - September 10, 2016

The sky this morning is partly clear but seeing condition is very good. AR2585 Sunspot Group is still beautiful despite the fact it is getting closer to the western limb. The huge dark filament is still visible exiting the western limb.

Solar Imaging Session - September 9, 2016

The sky this morning is cloudy and very hazy! Nevertheless, I still force myself to take some images of AR 2585 Sunspot Group so I can get a good monitoring of the group till it exits the Sun's western limb and expecting the images to be poor due to the weather condition this morning. The huge, long dark filament is still visible as it creeps toward the western limb.

Solar Imaging Session - September 8, 2016

The sky this morning is clear but slightly hazy. Seeing condition is again very good. AR2585 Sunspot Group is starting to deteriorate a bit specially on its rear umbral section. It is also showing some flaring activity inside its core.

Solar Imaging Session - September 6, 2016

The sky this morning is partly clear but seeing condition is very good. The appearances of both AR2585 Sunspot Group and the huge long dark filament is almost quite the same except for the very good seeing condition which I missed a lot in the past few month's of observation. I also modified and tested a bit of my new processing approach.

Solar Imaging Session - September 5, 2016

The sky this morning is partly clear and seeing condition is fair. AR2585 Sunspot Group is stretching to almost its actual size as it comes out of Wilson's Effect and is beautiful both in white light as well as Ha wavelength. The huge long dark filament beside AR2585 Sunspot Group is very prominent as well. A huge wide flat hedgerow prominence is visible in the SW limb.
