Coronado SolarMax II 90. SS & DS. 32x, 44.5X and 50x ( Ha )
I can see practically everything the GONG Cerro Tololo image shows today except in a red color! 5 plage regions are seen without difficulty along with a couple of other lower contrast disturbances on the Ha disc. AR12934 in the SE quadrant is easily seen with it's sizeable spot and scattered plage/disturbance. Just to it's west another plage disturbance is seen without difficulty. The SW quadrant shows a plage very near the limb. It's associated with AR12933. It's not difficult to see. A filament lies to it's SE. With difficulty I can make out a disturbance just east of AR12933. It has to be in the sweet spot to see at all.
The NW quadrant shows a not-difficult plage ( AR12932 ) with another just to it's SE. East of that plage in the NE quad lies a line of mottled somewhat lighter plage that crosses under a nice filament. I find that finding lower contrast detail visually requires correct tuning, utilizing the scope's sweet spot, double-stacking and of course experience. Seeing and the correct magnification for the feature viewed is essential too.
I picked out all the filaments shown on the GONG CT image. My favorite is a dark patchy one in the far south.
The SMII 90 is a prominence machine in singe-stack! I can see all of them shown on the GONG CT image. Detail can be seen in the prom on the SW limb. It looks much better in the " Nado ". It's overexposed on the GONG image. The NW quad shows a series of them low against the disc that looks better visually than in the GONG image. Another small bright one lies farther north of it. The NE limb shows a pair that resembles two horns! The solar devil shows again! I can also see the thin spicule layer on the limb at 50x.
The mottles are easily seen across the solar disc.
Celestron NexStar 102GT w/Altair wedge and Baader 540nm filter. 55x, 62.5x and 83x. ( WL )
I can see only three active regions on the 540nm photosphere today. AR12934 shows a single spot surrounded by faint faculae. The umbra of the spot is light bridged in it's southern portion. A small detached portion of the umbra in the eastern part of the spot shows a slightly lighter penumbral background around it. It's the only detail I could see within the penumbra itself. The SDO closeup image I attached shows this as well. I see a pore well to the NE of AR12934 and another pore well NW of it. AR12933 is seen near the limb in the far SW. It is visible as a small spot with a close look showing a penumbra. Two fairly bright patches of faculae flank it on the SE and NW. The third region is a faint patch of faculae near the NW limb. I see no spot or pore within it.
The fine solar granulation is easily seen today but the seeing is not good enough to attempt to see the individual cells.
Carpe Lumen!
