The sky this afternoon is partly cloudy and I have to fight the clouds for almost 3 hours under the heat if the Sun to get some decent shot of the Sun in Ha wavelength. 2 sunspot groups are visible with AR2709 Sunspot Group the slightly more prominent one than the departing AR2708 Sunspot Group which is near the western limb already. Both in white light are quite small and very inconspicious with pore light structure only. 2 nice prominences are visible in the NW and SW limb. There is also a possible new active region developing in between AR2709 and 2708 Sunspot Groups as it has some plage developing. I also use my old reliable TV-101 refractor for this session as it has been a very long while since I had used it so its a good time to let it taste the heat of the Sun once again.

Jupiter is at Opposition this evening so despite the fact that we here in the Philippines will be observing the boring side of Jupiter sans the Great Red Spot and Oval BA, I still try to setup and image tonight. Seeing condition is poor tonight. I was able to let the scope cool down for about an hour. Oh well, better luck this coming weekend again :0

Jupiter Imaging Session - May 6, 2018 The sky this evening is partly cloudy but I proceeded to try to image planet Jupiter with the Meade 8" f/10 SCT using ZWO ASI120MM webcam with 2x barlow lens and RGB filters. Seeing condition is not that good but I still proceeded after letting the scope cool down for almost 1.5 hours . The Great Red Spot is visible nearing Central Meridian, I also got to test my new Starbook-S which I locally made and it is working ok. I packed up after 3am feeling very tired but still happy that I was able to image Jupiter. I was planning to image Saturn and Mars as well but unfortunately, my Starbook-S battery run out so better luck next time.

I got to image the Summer Milky Way last April 15, 2018 under the dark skies of Caliraya , Laguna using Canon EOS M6 mirrorless camera on Canon EF-M 15-45mm f/3.5-6.3 lens set at 15mm f/3.5 mounted on Vixen Polarie star tracker. Total 7 minutes exposure at ISO 1600.

I got to test my old ATIK 16HR CCD camera to test image on the Quarter Moon mounted on Canon EF100-400mm f/4.5-5.6 IS L lens. My purpose to use it is to rehearse myself once again on how to use it. Also, I want to test on the new heat pads that I mounted near the camera sensor to see if it helps eliminate the frosting problem on this CCD as there is no Temperature Set Point on this old camera. After running it more than 1.5 hours, no frost on the CCD sensor so far so I guess it might be working. Looking forward to finally again use it since 2016. I also found out that this sensitive camera is prone to light bleeding if used on a bright subject such as the Moon so I tried using a red filter but I still get some light bleeding a bit but is a bit better than without any filter installed to dim the Moon further. Anyway, the bleeding was further removed with some processing. The session run quite ok and I'm very happy on the result so Im looking forward to the next Caliraya session in March and hopefully get some deep sky images there.
