About Astrojohn

I am a science geek! Interests Astronomy, Skiing, Philosophy, basically any form of technology including writing automation software for my observatory. I will also share this with others using the same EQMOD/Astroart tool set.

You will need to know the format of files in your TEMP files

I have included a sample TEMP file for the ObsMGr10. This gives you the file naming conventions I have used for Master Darks and Flats:
MD30B1 for example is a 30 sec master dark binned 1X1
For the flats the names are more obvious except that after L,R,G,B I have used filter slot numbers. eg I have a Johnson V filter in slot 6.

Hope you can make sense of this.

Clearly there is a lot of system setup to do before you have full automation, but once done it makes life very easy to get say 100 variable star measurements for a time series curve. All automated and checked for accuracy and noise level.

Hope this helps.

Latest measurement of V0470 CAM close binary pair.

You can see the initial readings are at the secondary minima.

This measurement of the primary minima (in BJD) will go into the data set to estimate the changes in the binary pair period.
Strange bright spot at minima??

Just a quick image as I was trying to set up my new SA200.
Without much success!!
