ItsmeMaw Posted October 16, 2021 Share Posted October 16, 2021 Am I correct in thinking from the phase Venus is showing it is near maximum elongation? Two evenings ago it was very beautiful in the twilight sky. Link to comment Share on other sites More sharing options...
Nik271 Posted October 16, 2021 Share Posted October 16, 2021 Yes, it's pretty close to the maximal elongation, which is at the end of October I think. Because it's far away from the Sun you can also find and look at it in the afternoon even before sunset. Binoculars show it easily. Link to comment Share on other sites More sharing options...
IB20 Posted October 21, 2021 Share Posted October 21, 2021 I saw Venus had appeared in a gap between two neighbouring houses 30 mins so threw the 80mm frac up. Being still relatively light I found aligning and focusing quite difficult, but once I got it honed in I was amazed at what I could see. It’s my first time viewing Venus through a scope and I was quite surprised with the disc size but more so with how defined the phase was. Atmospheric dispersion was quite pronounced but it appeared as a perfect white semi circle with red and blue fringing. No signs of CA which I’m delighted about. Just Mercury to go! 1 Link to comment Share on other sites More sharing options...
Stu Posted October 21, 2021 Share Posted October 21, 2021 Just been having a look myself. Plenty of atmospheric dispersion as mentioned but a very clear phase. Looks like it is at 53% illumination with maximum elongation on 29th October. 1 Link to comment Share on other sites More sharing options...
Gonariu Posted October 21, 2021 Share Posted October 21, 2021 I saw it a few weeks ago with the Vixen 102/1000, not very high in the sky but they were windy days when the air was agitated. However, the phase stood out well, practically a half moon. 2 Link to comment Share on other sites More sharing options...
CentaurZ Posted October 22, 2021 Share Posted October 22, 2021 (edited) Venus' dichotomy (half phase - 50% illumination) is expected on October 22. Greatest eastern elongation from the Sun is expected on October 29. The difference in timing is twofold: The orbits of Venus and Earth are slightly eccentric, and observed eastern dichotomy usually occurs about 6 or 7 days earlier then would be expected from geometric calculations, likely due to a Venusian atmospheric effect.
