Hi Miguel,

I've got some material of NovaCyg on Fri (cloudy) + Sat evening, managed to try a Hg lamp on Sat (surprised later it's not a Ne lamp), using A4 papers as diffuser (ambient light needed too much exposure).
Still learning the workaround in ISIS for Hg, looks that He/Ar hardwired by code for the mixed mode calibration assistant, I may define the lines by hand or by file anyhow.

Also learned for the UV part even with Alpy calibration module the Balmer lines + lookup the RV of ref. star still needed.

But having faced these lamp troubles manually (I'd never make such remote), I learned now that the Alpy lamp is the way to go on with, so got a deep breath and ordered one (3 weeks to arrive, but won't have an observing place available for this period as well).

Is there a reason not following Robin's approach? (http://www.spectro-aras.com/forum/viewt ... ?f=8&t=713)
I'd rather go on with the USB if not too expensive (have nothing like a focuser), even if I must re-solder the switches (breaking the guarantee), though I'm not an electric engineer.
Any hints appreciated.

Clear skies,
Peter

Quick Update:
I'm just through the lamp pdf, there are already 12V input for remote control, only the two USB - 12V switching must be resolved.
Assume already have such on device the market, interesed only where to get from.

This could be a good simple solution. Better than mine and and probably cheaper too now the price of these boards have been reduced (22UKP ~ 28 Euro)

Thanks Robin, meanwhile I've also found a similarly cheap USB relay here:

From here it's only cabling work - that we amateurs do every day.

Calibration module has arrived and tried, using it from now.
