New picture of Omega Centauri.


In May 31 2011, I will use the telescope for the first time with his new
base. This is a photo of Omega Centauri. Subs are 46 minutes in 120 " to ISO 1600 with a filter Celestron UHC / LPR.
10 Darks, 10 Offsets and 10 Flats. Processed with Photo Shop, Gimp and
pixinsight. It is not extraordinary. But
it is my first photo with this base.

Area near the northern border of Corona Australis. Clouds of dust spread by the stellar field blocking the light of background stars in the Milky Way, and within 500 light years away, the most dense cloud of dust (which here is seen as an area with no stars ), is about 8 light-years long.
Top left, a group of reflection nebulae, NGC6726, NGC 6727, NGC 6729 and IC 4812. The blue color is produced by light from hot young stars which is reflected in the dust of the nebula.
In the center of the image, the globular cluster NGC 6723, a light 28600 years away. Opening 13 '. Visual magnitude: 6.8.

CONSTRUCTION OF A RIGID BASE FOR MY TELESCOPE.

This is the change of the tripod of the telescope by a more rigid pier.

PIER PLANS


Main Plan


View of the pier head, with the base of the telescope in place.


Plane of the first base, this base is welded to the pipe.


Plane of the second base. This base is on first base, supported by the 4 threaded rods 3 / 4 ".


Plane of the second pier base with the projection of the pipe and the base of the telescope.


Pipe with a diameter of 100 mm with its base.


My brother Luis is welding the base to the pipe.


Detail of the base and the telescope


Another photo of the installation.

I hope this information is helpful to someone.

Bahtinov: Building a focuser for telescope.

This device is helpful for a successful approach to the images when shooting the sky with a Newtonian telescope.



The device causes an optical interference phenomenon that transforms the image point of a star in a picture of this type.


Adjusting the telescope's focuser is changed that image. This coincides with the focused image of the telescope.



There are web sites to design the mask Bahtinov for each telescope. This figure is for my telescope Hokenn 200/1000. The maximum diameter is equal to the diameter of the mirror.


To build the Bathinov I used cardboard from a folder, very hard, about 2 mm thick. I printed a 1:1 scale design and paste it into the carton.


Cutting the mask with a cutter.


Mask painted with matte black spray paint.


Wire supports, to keep the mask in place at the entrance of the telescope.


Bahtinov installed on the telescope.

Building Observatory

The observatory is located on my house.

The diagram below is the previous project. On the terrace built the office and on this, the observatory with a roll off roof type.
