Following up on Jack’s question. I am an occasional spectroscopy observer having built a Sol’Ex and Star’Ex spectroscope with the hires and lores optical kits from Shelyak based on the Christian Buil designs. I have also used PHD2 and guided on slit but also using field stars with the PHD2 multiple star guiding approach. For the limited amount I have done (relatively short exposures) it seems to perform ok. (I run Sharpcap and PHD2 for acquisition)

Christian Buil advocates using CCDCiel which also does slit guiding – I haven’t yet tried that so interested if any more experienced users here have done so?

Bingo!
I just ran CCD DP tool with FITS header enabled and the Coordinate COnverter tool set up for the target and obsy location.
So no NaNs in the measurements table and BAAVSS spreadsheet worked fine

Thanks for those hints John!

Hi John,
I do have some NaN under various fields. I didn’t use AIJ DP for data reduction (I actually used ASTAP to get calibrated science frames) so not sure if the DP Coordinate Converter module was used. I don’t see ALT_OBJ in the Fits header but I have since checked the aperture settings keywords and used the default ones suggested in AIJ doc (JD_SOBS,JD_UTC,HJD_UTC,BJD_TDB,ALT_OBJ,AIRMASS,CCD-TEMP,EXPTIME,RAOBJ2K,DECOBJ2K) – again resulting in some NaN presumably since some don’t exist in the FIits header. I will try to use the CCD DP module to edit/enable those keywords – didn’t realise I would need to do this!
I’ll email you separately to connect and maybe follow up if that’s ok
Thanks, Les

Looks like the forum won’t allow me to upload the BAA_Photometry_Spreadsheet_2.22.xlsm…possibly since it contains macros?
