Venus 12% Illuminated
This evening Venus is still very bright and shining after sunset. I made some pictures using my TAL200K f/8.5 telescoop with ZWO224MC camera and ADC (Atmospheric Dispersion Corrector). Pictures are stacked using Autostakkert! and final editing with CS4.

Antennae Galaxies NGC 4038/4039
Galaxies NGC 4038/4039 also know as the Antennae Galaxies are located in constellation Corvus and about 45 million lightyears away from Earth.
The Antennae Galaxies are an example of colliding galaxies. In better circumstances and longer exposure time it should be possible to see the antennae. Yesterday conditions were moderate with Moonlight (75%) and 100% relative humidity.
Setting: Nikon D7500 and TAL200K f/8.5; ISO 1600 and 21x60s exposure time. Stacking with DeepSkyStacker and final editing using CS4.

Galaxies NGC 4762 and NGC 4754 - Use of PAE
Both galaxies NGC 4762 and NGC 4754 are located in constellation Virgo and both are part of the Virgo Cluster. NGC 4762 is located at a distance of 60 million lightyears from Earth; NGC 4754 about 53 million light years.
Setting: Nikon D7500 and TAL200K f/8.5, ISO3200 and 46x60s exposure time. Stacking using DeepSkyStacker and final editing using CS4.
The equatorial mount and Synscan v4 was connected to my PC and Stellarium software. After 3 star allignment the mount was set to a nearby star and again corrected via PAE, Point Accurancy Enhancement. The nearby star was centered and via menu Utililty, PAE corrected. This was a great help to located the galaxies.
