Better late then never.....I've been taking Alpy600, LISA-IR, and LhiresIII data in Ha, Hb, & CaK. First here is a stitched Alpy600+LISA-IR spectrum (Taken on the 4&5Dec20...I have more but wanted to do this pair first): http://astroimage.info/spectra/Nova%20Per%202020Vis&Ir.png NOTE: Al...

RE:"Christian, As I am considering purchasing a Canon 135mm f/2 L lens I will need to 3D print an adapter to the eShel. Do you have an STL file for this? " Bernard, Shelyak provides an adapter between the eShel and Canon 135 F/2 lens...I just got mine last month! Now all I need is this $4K...

I'm on my 40th try to get the orientation and dispersion correct on my eShel2, but thought the experts here can get me a faster answer. Here is where I'm at now: http://astroimage.info/spectra/eShelROTissue15Oct20.jpg I've successfully completed the "Camera Rotation test", but can't procee...

Nice discussion on the eShel! I'm still trying to figure out my DEF_ORDER. LST file. One confusing thing I notice is when Isis displays the 2d .fits image, it displays it with a vertical mirror image; I noticed this with Alpy and LISA processing previously. Hopefully I'll be able to process my 1st e...

Isis can be tricky. I'm only on V5.9.3, but will migrate to V6 when my eShel2 is complete. What I find helpful it to make a small notepad file with all the various configs and locations I use for my LhiresIII, Alpy600, & LISA-IR observations, like this: __________________________________________...
