Re: V694 Mon

I also succeeded in taking spectra of this star last night.
Similar to Forrest's data.

There are 3 prototypes of the guidance module, in test phase. The results seem good. It is necessary to wait a little longer, the parts will be published in not too long (it is a complete set, which covers the optical, mechanical and electronic aspects).

Thanks

My effort from tonight using a Lospec with a 1200l/mm grating. R=4900.

Re: Call for monitoring Be stars in the TESS sectors

All are very northern targets so I'm afraid I won't be able to contribute.

Re: Study of spectroscopic binary star

I was all ready to get some high R (Greater than 10K) resolution spectroscopic binary data, but when i clicked the installer it was a broken link; see: https://www.vub.be/STER/JAD/JAD10/jad10_3/install.msi .

Re: UVEX3 N2

Hi all I am thinking about making one of these spectrographs. I have made a LOSPEC that works very well. I have a LISA so don't really need another low res spectrograph but I think the idea is fun anyway and it would probably compliment the LISA in the blue end of the spectrum. What is holding me ba...
