The Pleiades seen by Coolpix S3300 , January 9.
Only six stars.
Poor limiting magnitude , my best naked eyes observation counts more stars than this picture.

Gamma Leporis ,Sigma 747 ,Sigma Ori and Sigma 761 observed with the 45mm refractor stopped down to an aperture of 25mm.
The aim was to reenact some early double star observations.
The refractor was operating in the straight-through mode at 13x with a DIY -23mm Galilean ocular.

 On 18 January I start to juggle with filters.
Here we see the observations of the Merope Nebula known also as Tempels Nebula or NGC 1435.
And of the Messier1 and of Venus.
I was  using my 125mm F/7 Dobsonian and an Optolong UHC filter on Mesier1 and NGC 1435.
At Venus I used a Green #56 color filter.
Filters are not doing miracles but are useful accesories.
