An unconfined vagrant? but if!

 

We thought she was going to escape to the East, she is close to being called back to the West in a few days. Everyone is confined, even the planets by Newton's laws. The planet Venus, a wandering star, almost reaches its maximum eastern elongation. It is very bright (magnitude -4.46), which makes it easily observable in broad daylight, even with binoculars! So here is its appearance behind a 16" dobsonian scope yesterday around 4 p.m. local time when crossing the meridian. Being able to observe it so high at an altitude of almost 60 ° eliminates the problems associated with atmospheric refraction. About turbulence, quite intense in the afternoon, you have to be patient because it is able to calm down from time to time. So it's fortune, because we can see some sort of cloudy bands. Take a good look at the drawing, this is roughly the appearance behind the eyepiece.

 

Digital sketch made from field observation notes with 16" dobsonian scope, Celestron 25mm eyepiece and Barlow Powermate x2.5, gray ND 96-0.9 filter and a blue # 80A color filter.

Hi Franc. 

 

I greatly admire the blue sky around the brightest planet Venus. 

In about 1.5 hours I will be setting up my William Optics 158 mm f/7 apochromatic refractor. 

Venus will be my first celestial object. 

 

Next Thursday it will be 50% illuminated. 

Perhaps you would consider giving us another excellent sketch then. 

 

Best regards, 

 

Aubrey.

The bigger scope will not show the  more detailed views especially Under seeing rather average to strong.

I think you may get more with a simple 4-6" aperture also affected by the seeing but at a substantially less level.

Matter of compromise and planet surface light level involving glaring.

If you interested: http://alpo-j.sakura.ne.jp/indexE.htm

especially for 15th march (with 2 visual observers) and the 21st for comparison.

Thank you Stanislas-Jean,

 

Of course my scope is not adapted to such kind of observation, but I am no more adapted to stay confined at home, so what else to do than trying different things smile.gif ?

Any way, thank you very much for the link and uplifting comparisons, 

 

Kind regards,

Francis

I'm afraid not, Franc. 

Even though the shimmering did die down as 6 pm approached. 

I used 225X in the end with a 5 mm Nagler eyepiece. 

And I did greatly admire the 52% phase. 

It's lovely and white. 

I did have fun splitting Epsilon Arietis at 167X and 225X. 

That wonderful true binary was in the same field of view as Venus at 40X. 

The planet is seriously high in the sky from 53 degrees north.

 

Please do include more sketches of Venus, Franc - especially when it becomes a crescent. 

 

Kind regards, 

 

Aubrey.

Francis,

 

A very nice sketch of planet Venus.

 

Frank :)
