Excellent thanks for the link Jean-Pierre . Seems quite a good match with observer JMO`s shot from 02/10/15
I didn`t know about the A.R.A.S. spectral database looks very useful.

Hi Paul I don`t have the Alpy calibration module and have never had any calibration issues with Isis just using one of those Relco bulbs at the end of my refractor. I did wonder if I would gain anything by having it at the ccd end although I have read an article describing using a tilt mirror setup ...

Hi Paul/Keith
If its still of any interest this is a 120sec shot of a Relco starter bulb positioned at the objective end of my 120mm apo refractor. Isis seems to be fine using it for calibration.
uncalibrated regards

Hi guys. I tried a few shots of the Symbiotic star UV Auriga (HD34842) last night but can`t seem to find any spectra of this star to compare it with. I noticed it had very clear Hα and NaI lines and at first I was'nt sure it was the right star!. Simbad describes it as a C8 type spectrum uvAur.png Co...

I think it might be HeII !

Hi
Took some spectra of these two objects last night and although they are quite similar I wondered if anyone could tell me what the line around 4690 angst on the ag Peg profile is likely to be please?.

thanks

Hi Francois

Hi Paul
Probably a daft question and someone will no doubt correct me but are you using an unbinned 1x1 or 2x2 binned image as I gather you have to double the pixel size if using a 2x2 one?.
