¿ªÔÆÌåÓýThanks Wolfgang. What software do you use to record atomic hydrogen (sorry about that mistake thanks for correcting me) over time so that it can be processed to display the distribution in the Galaxy on a graph?

Hi Andy, When you point straight up you will collect data for one declination only, it will be the same every day. So you will need to change position of your antenna. Same comment as in the other forum: You are observing emission from atomic hydrogen, not molecular hydrogen. Good luck with your observations, Wolfgang ? ?

Andrew Thornett via groups.io ? Can I ask what members of this group think is best way to record and display my data? I am hoping to collect data over 1 year. Do I need to vary position of array or would pointing straight up for the whole year be adequate to obtain spectra from large part of Milky Way? Andy ? From:

On Behalf Of Andrew Thornett via groups.io ? Hi All, Wow! Success 2 days ago with Triffid array and SDR.- successfully detected galactic hydrogen as per attached radio spectrum.?I am actually quite shocked as I am not used to my radio astronomy experiments working!! (Only just managed to get meteor detection from Graves working after about 5 years!) ¨C and this was achieved within 2 weeks of starting data collection on this project which is truly amazing for me. However, I really need to give all the credit to Andy Thomas from this group, who generously gave me his Pharmigan Triffid military phased array. This is a wonderful piece of kit: (i)??????????? Seems to work MUCH better than similarly sized satellite dish on 1420MHz. (ii)?????????? Has better sky resolution than similarly sized dish. (iii)????????? My wife is happy with the look, whereas she can¡¯t stand a dish, and has (incredibly) given me permission to mount the aerial on the patio long term (which I still can¡¯t believe). (iv)????????? Everything thinks the horizontally mounted array looks like a BB, and hence fits in to the garden more easily. (v)?????????? ? Andy ? Attachments:
