Observations January-March 2017- P II

The Moon on 10 February through the lens of Coolpix S 3300 , mounted on a Velbon tripod.

Afocal pictures on 23 February 2017  : TS 100mm F/14 Maksutov - Cassegrainian at 56x / Sirius Plossl 25mm ,Coolpix S3300 , DIY pipe -mount.

Mizar ,Alcor , Sidus Ludoviciana

Regulus A+BC

Sigma Tauri

Cor Caroli /Alpha Canum Venaticorum 

Sirius and Venus on 25 of February , only  Coolpix S3300 :



Venus on 27 February , surrounded by a halo.
In the picture ,the diameter of the ''Venusian'' halo is smaller than what I saw visually.
Visually ,the diameter of the halo was about half the length of a brick also visible in the picture.
Knowing the distance to the wall and the dimensions of a brick and  using the ''arctan'' function I found for the halo a diameter of 0,32 degree or 19 minutes of arc.

On 28 February Venus was close to the two days old Moon.

Trying to capture the Winter Hexagon  with Coolpix S3300 , I missed Capella.

On the 3-rd of March I took afocal pics of the Moon in the day light using my 90X600mm  RFT refractor  at 24x / Sirius Plossl 25mm +Coolpix S3300 + SV Bony Moon&Skyglow filter.

This is a ''day light'' picture  of the Moon taken with only the Coolpix S3300 camera.

In the dusk  of the same day the Moon , Mars and Venus were lined on the Western sky .

On 4 March the Moon was in conjunction with Aldebaran as recorded below by the Coolpix S3300 camera.

For visual and afocal pictures of the Moon I used that night my trusty RFT 90x600mm refractor made by ''zoth''.

On 13 March the Full Moon ,known as ''Worm Moon'' ,accompanied by Jupiter to the South , put up for a nice and colorful show !

On March 15 I was finally successful at recording the Winter Hexagon and the Winter Triangle.
Just in time !

Conjunction of Moon and Aldebaran on 9 January 2017

A somewhat closer look at the Moon-Aldebaran conjunction of 9 January 2017

Visual observation of the Moon-Aldebaran conjunction on 9 January through my 45mmx300mm ''beer bottle'' refractor at 12x / 25mm Sirius Plossl.

The main stars of Orion as recorded by the Nikon Coolpix S3300 camera on 9 of January.


Labeled picture of the main stars of Orion.
Beta Eridani is also visible.

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.

Venus and Mars above background trees on 9 of January.

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.
