Libration and near side of the Moon

Posted on July 19, 2021February 3, 2022

As is mention on the wikipedia:

Since the Moon’s orbit is both somewhat elliptical and inclined to its equatorial plane, libration allows up to 59% of the Moon’s surface to be viewed from Earth (though only half at any moment from any point).

The central crater in the picture is Pitiscus​​​​​​​, it’s around 82 km in diameter.

Anyway, it’s an another exercise performing more tests on the new remote planetary config.

This picture was taken using a QHYCCD QHY5III174 with a Baader Q Barlow on a camera DIY switch.

It was taken at 3800mm f/19 with a GSO 8″ f/12 Classical Cassegrain Reflector using an Astronomik ProPlanet 642 BP IR-pass filter.

With this config I am covering a field of 10.2 x 6.37 arcmin at 0.319 arcsec/pixel.

It was a video of 10k frames at 80fps using only the best 1% of them.

This DIY switch allows me to change between two cameras, currently this QHYCCD and other ASI183MM-C for bigger field of view.

Also this high resolution three teselas mosaic was compose with the the big ASI183MM-C at the same night.

In that case is a three teselas image merging three videos with a luminance filter at native 2500mm f/12.

It’s amazing how well it performs!!! Excited waiting better seeing!!!!
