Lunar X and Lunar V ,crepuscular rays and planetary conjunctions

On June 20 I observed the ''Lunar X'' and ''Lunar V''  using my ''zoth'' 90x600mm refractor.

My ''zoth''  90x600 mm refractor 


Visual observations were made at 60x/ Plossl 10mm  and 100x / BCO 6mm.
The pics were taken in the afocal mode at 60 x with the Coolpix S3300 camera.
This is my second ''LunarX-Lunar V'' observation of  this ''light and shadow'' show of the Moon.







On July 14 I was preparing this Summer wine.



Above , on the sky it were visible for a long while spectacular crepuscular rays.





On the evening of July 15 the planet Venus was close to the Moon while Lady Luna was in conjuction with the star Regulus.
The Ashen Light was well visible on the Moon.

Idele lui Marte : Mercur ,Venus, Triunghiul de iarna si un crepuscul purpuriu

La 13 Martie 2018 am observat vizual si fotografic apropierea aparenta a planetelor Mercur si Venus pe cerul vestic.
Am efectuat  observatiile vizuale cu ochiul liber si cu binoclul galilean ''Hapo Lord'' 3.6x40mm.
Pentru fotografii am folosit camera compacta Nikon Coolpix S3300 montata pe trepied.




Intai , pe cerul de seara s-a vazut numai Mercur deasupra unor nori.





Mercur , in centrul imaginii , imediat deasupra norilor.


Apoi a inceput sa se vada si planeta Venus.
In aceste fotografii Mercur se vede la dreapta sus fata de Venus .


Au fost intervale de timp in care se vedea numai Venus.






In aceeasi seara , am reusit sa fotografiez (din nou ) ''Triunghiul de iarna '' format de stelele Betelgeus,Sirius si Procyon.

Pe data de 22 Martie 2018 am observat un crepuscul de seara minunat de colorat.

Crepuscular rays and twilight on October 31

Before sunset ,on 31-st of October I witnessed crepuscular rays on the Western sky.




The premises were  promising for a beautiful twilight show.
Which actually happened.
The twilight is ''universal'' , embrassing the whole world as seen by the observer.

The twilight noticed on Northern sky.

                                                                             



The twilight seen on the Southern sky.

                                                                              

The twilight seen on the Eastern sky.

                                                                                

At sunset ,the most spectacular twilight  is seen on the Western sky.
All the following pictures were taken on the Western horizon with my Nikon Coolpix S3300 compact camera on Velbon photo tripod.
