f/50 25cm speculum Mutoh CV-04
On 12 Apr (103°Ls) at ω=290°W, Hellas is considerably light even in Red.
The images on 13 Apr also show the same. (As remarked before his B light image does not work well, but Hellas looks much brighter in B).
The images on 16 Apr (105°Ls) at ω=274°W, and 283°W are good, where Hellas and Ausonia are separated. There must be a bright patch at Zephyria in the evening. N Alcyonius is evident.
On 19 Apr (106°Ls) at ω=210°W and 229°W, Elysium and Cebrenia are well light in a shape of a heart. The npc looks complexed (should be more image processed). HIGA's phenomenon is not seen because the B light image is dull. Elysium and Cebrenia are seen similarly on 24, 25 Apr. Propontis I is always apparent.
On 4 May (113°Ls) at ω=096°W, 107°W, M Acidalium is seen in the evening. Tempe is light in R.
The dark markings are well seen on 5 May (114°Ls) at ω=073°W, especially Mareotis L is dark evident. The npc is tiny but definite. B images fail to show the interesting morning area.
On 17 May (119°Ls) at ω=321°W, Hellas is light again.
Hellas is near the CM on 22 May (122°Ls) at ω=293°W and 302°W, seen also through G.
Interesting image on 24 May (123°Ls) at ω=247°W, but the diameter now not enough.
Elysium light on 25 May (123°Ls) at ω=236°W.
On 31 May (126°Ls), Cebrenia looks light. The apparent diameter is 9.1".
Notable is that on 7 June (129°Ls) at ω=115°W, Tempe is roundish light in R (seen creamy light also visually at Fukui; cf #192 p2108).
The image on 12 June (132°Ls) at ω=098°W also shows the same.
The image on 29 June (140°Ls) at ω=263°W is also a good image.
As July comes in, no more than large markings are seen, but the last one taken 21 July (151°Ls) at ω=046°W is better and Chryse and Deucalionis R near the evening limb are well shot.
