Venus Image 2019/04/14(UT)
Here is a report of venus perfomed on 14th april with the same 150mm refractor,
a little too big with regards the local seeing, upper atmosphere and local.
With these poor to average conditions some atmospheric color aberration were on board.
Any report without this observation can be subject to doubt
a disk with on upper sides at the eyepiece, reddish and whitish blue. Not concerning only refractors,
but all designs, depending on the time of observation, not concerning obligatory poles,
and even in a 100mm.
Anyway the 150 help me to recognise the bright poles, and some parts of the banding pattern.
Some brightenings were on board on short moments as given.
Would be rather on a 100mm for geting a little more acurate,
weather is changing here and in few days we will have 22°C; now only 8°C.
I intended to make a venus planisphere at the issue of the 4 days period,
but this is a little compromise with seeing not cooperating.
