| VENUS - February 26th 2017 - 18h 15m UT- Jason 60mm/f15 O.G. |
This chilly February evening still gripped by the days north wind didn't at first inspire confidence of an observation of Venus.
But as the sky darkened and the many clouds turned to black, Venus in solitude shining brightly in the west silenced my wintry complaints.
The Jason (60mm/f15) refractor was close to hand and within minutes was in the back garden, partially protected by hedge and shed wall.
Tonight would allow a test of my new "plastic" Huygens eyepieces.
Three oculars in all, a 20mm, 12.5mm and 4mm.I had no idea how well they would work on such a bright object as Venus.
Being that all three are about the cheapest eyepieces you could buy I didn't have high expectations.
The 20mm and 12.5mm eyepieces returned lovely sharp views of the planet, with no false colour noted.
Next was the real test, the 4mm! Again a surprise, no false colour, no sparkly rainbow effects, just simply an enlarged sharp image of the waning crescent Venus.
To begin with I was dubious that any of the three eyepieces would deliver a clear image, probably the colour correction was helped by the focal length of Jason, being an f15 scope it is very forgiving of cheap eyepieces.
If I had used a telescope of f5 focal length I would probably have seen a lovely rainbow and fireworks display, I will have to try out these eyepieces on my f5 reflector one day soon.After making a quick sketch of Venus it was time to pack up.
The north wind and the ever multiplying clouds told me to clear off and go back to the warmth of our kitchen..!
I was more than happy to oblige.
