    Is that telescope permanently mounted in that location?

    I have two mounts.

    The larger one, an EQ6, stays semi put in the city.

    I am developing a cheap approach to an observatory with my "Cube".
    It is only 4ft x 4 ft but takes the 8 inch.
    I designed it to be able to use 8 x 4 sheets of ply which I had cut at the store.
    The semi permanent set up sees each of my scopes in it but the mount does not change.
    I did some sums to indicate an entry level if anyone wants to have a serious go.
    Eight inch scope say $500 or less.
    EQ5 mount ( my small mount) say $1000 abouts and a dslr say $500.
    So two and a half K will see you well set up.
    The mount is the most important part of the game...better to have a good mount and a poor scope than the other way about.
    You can easily spend $25,000 for a very good mount, $25,000 for a scope and $25,000 for a camera...
    Like cars but the expensive one few can manage to drive to potential.
    Here is my cube it has progressed past these photos but I am not there and these are all I have.

    Processing images is perhaps 50% or more of the game than aquiring data.

    I have been learning how to use a program called Startools and have reached a basic level of using that program.

    This image was a stack of all the data (3 hours made up of 30 second captures) I had taken with my Nikon D5500 DSLR 24 meg thru my 8 inch F5 Newtonian telescope (which cost under $500 but has additional coma corrector $300 or thereabouts) and processed in Startools($60?)

    I am very pleased with the result which has taken my processing to a higher level.

    I am still learning how to process the narrow band images with Startools which will take a little more study.

    Mmm it seems to have lost quality due to making the file small ..I will see if I can download a better version later.
