I got these for a project that never materialised. Both are still in the original packing and I include a photometric slit.
Please contact me if you are interested.

Asking £700 plus shipping for both units with the additional slit.

I have been looking at this configuration as a possible way to do very low resolution spectra of flare stars with less glass and unknown coating that my current spectrograph. One issue that puzzled me was the correct focal surface to use as I wished to offset from the zero order focus to allow remot...

I have converted some CALSPEC spectrophotometry standatds to .dat as they are in Fits table format. I have tried converting to normal fits using the ISIS-> profile -> save function and saving as .fit However I find there seems to be an error in the conversion. See the comparison. ISIS Dat to Fit.png...

I find the latest version does not normalise the @pro# products and the unnormalised product are as expected so the problem is "solved".

I have been using ISIS to process my flare star spectra. I need to process some 80 or so spectra so have been using the @pro# products to give the individual spectra. However, I find the @pro1 product is scaled differently to the rest. To test this I copied the same image 3 time and made them into a...

I have now a accumulated a number of M Dwarf flare spectra. I need to reduce 50 to 100 spectra per flare even as a time series I.e. reduced as individual spectra. Can anyone advise tbe best software to do this automatically. IRAF? :ugeek: Tõnis Yes I have used it for my Echelle spectra but I was ho...
