Hi
Here are the results of my attempts at AG Dra and calibrating using ISIS (still on learning curve with the software). Using my C9.25 @f6.3 and ALPY 600 with 23um slit and 314L I captured first set of 4x300sec on the night of the 23rd April and again another set of 3x300sec last night,used the calibration module to collect flats and darks and Ar/Neon lines.
No Instrument Response correction carried out at this stage.
Regards
Alun

Hi Alun,
It looks correct. Congratulations!
Next step : intrumental/atmospheric response (not the easiest!)
All the best,
François Teyssier

Hi Francois,
Thank you,looking at Cartes Du Ciel map I have found an A3 star reasonably near to AG Dra (HD143933) so next clear session I get I will use it as my reference
star.

Alun

Hi Alun,
To find a good reference star you can use the spreadsheet of François :

Actually, for AG Dra I use HD 155763, a B6III in Miles database

Hi Olivier,
Thank you for the spreadsheet,will make good use of that.
HD 155763 will be a much better choice being a lot brighter at magnitude 3 compared to magnitude 8 for the star I'd chosen so,again, thank you for the tip.
