Solar Imaging Session - July 20, 2026

The sky this morning is partly clear and seeing condition is very good. AR4489 Region continues to be stable in term of size while AR4492 Region that is entering the NE limb might replace AR4489 Region as the next big active region to monitor in the days to come. New AR4493 Region is growing also in structure and forms a ring appearance. In Ha wavelength, AR4489 Region together with a widening and long twisting dark filament in the same field of view forms a beautiful photogenic area to image.AR4492 Region is likewise beautiful as there is a beautiful eruptive prominence in the NE limb. There is also a pair of long twisting dark filament in the NW quadrant. AR4493 Region is active with flaring activity despite its small group.

The sky this afternoon is clear and seeing condition is very good. AR4489 Region is stable and quiet in terms of size with another small AR4491 Region that is trailing behind the bigger AR4489 Region. In Ha wavelength, AR4489 Region have 2 small, bright dot flares beside the main group and also a beautiful twisting dark filament on the same field of view to make it photogenic to image and view. There is also a nice SE floating prominence near small AR4491 Region as well. A very quiet Sun indeed.

Deep Sky Imaging Session - July 17, 2026

The sky this evening is partly clear so I use this opportunity to test some wide field image of M8 Lagoon Nebula and M20 Triffid Nebula using my ZWO ASI294MC PRO Astro Camera on Canon EF100-400mm f/4.5-5.6 IS L Lens set at 200mm f/4.5 with STC AstroMultiSpectra Broadband Filter on ZWO AM5 mount. Unfortunately, clouds started to cover up the sky and this prevented me from doing my usual 2-3 hours exposure to a measly 30 minutes total exposure only. Anyway, still happy to test the new configuration and hopefully can get better integration data next time around.

Comet Imaging Session - July 17, 2026

The sky this evening is partly clear and it's been a while since April that I had done any night time imaging. After midnight, I set my Dwarf 3 Smart Scope and capture periodic comet 10/P Tempel 2 which is shining around mag +8.2 in the constellation of Capricornus. I use Astro Mode with Astro Filter at EQ Mode and expose for 10 minutes (20 x 30 sec) at Gain 60.

Solar Imaging Session - July 16, 2026

The sky this morning is clear and seeing condition is good. AR4482 Region is near the western limb already and probably will exit tomorrow. AR4489 Region is steady in size so far while a new AR4490 Region is growing north of AR4489 Region. There is also another new possible small AR4491 Region emerging from the SE limb as well. In Ha, all groups are quiet so far and there are 2 beautiful twisting long dark filament on the Sun's disk .

My July 1, 2026 Ha image of AR4478 Region got mentioned by David J. Eicher :)

My july 1, 2026 Ha image of AR4478 Region got mentioned by former Astronomy editor David J. Eicher on his FB post. Thanks David!

Solar Imaging Session - July 15, 2026

The sky this morning is very hazy and some clouds also hovering on the Sun! Add to that I wake up late this morning so I had to do quickie shots before I get obstructed by parking area roofdeck! Seeing condition is also poor this morning. AR4482 Region is nearing the western limb while AR4489 Region is entering more from the eastern limb.
