Re: 20m radio telescope at Greenbank


 

¿ªÔÆÌåÓý

I used to pay for access to Siding Spring Observatory scopes via and it was a very useful, if expensive, way to avoid my local light pollution issues for optical astronomy. I didn't know there were options to get time on professional radio instruments, very interesting.?

There are some small radiotelescopes with remote access, but they are limited size and frequency range.
and are two I'm aware of.

I think were working on an interferometer interface unit for their dishes/drives/receivers/spectrometers, that could get interesting, at least for folks with deep pockets.? I'd love to find some other folks within 10-200 km of my location in East Yorkshire who would like to try some VLBI linking of amateur radiotelescopes for pulsar observations. The technical contraints are challenging to put it mildly!

I advise choosing your life partner VERY carefully, selecting only those who will be entirely accepting of mad antenna projects in the garden. My late wife was totally chilled about all of my skyhook projects, never even raising an eyebrow in the 37 years we were together, despite dishes, 100ft masts, yagi arrays and 200 metre long wire antenna systems and a couple of miles of ground screen for VLF.

Anyone else know of subscription deals for similar radio telescopes, preferably with a range of frequencies suited to pulsar observations (2/4/8 GHz pref)

Perhaps BAA RAG should see if they can get access to a professional dish in the UK for members to get access to?
