If you intend to obtain an AVI while using a LhiresIII spectrograph, then remove the guide camera....
It is not necessary to use any added filters before the entrance slit - the amount of light/ energy transmitted through the 15 micron slit gap is very small. This is then spread across the spectrum.
I have a SimSpec SHG spreadsheet available to assist in evaluating the solar image size and probable resolution....
Once the AVI has been processed to a final image corrections can be applied to "improve" it.
Wah! Spectral Line Merge (SliM) program is very good and his tutorial is helpful (available on the files area of the Solar Chat site https://solarchatforum.com/viewtopic.ph ... 9a#p209997 )
