Re: USB remote control for ALPY/LHIRES etc ... François, I have a project on the go to do something similar for my L200 using an Arduino nano. My intention is to emulate one of the popular filter

      Re: USB remote control for ALPY/LHIRES etc François, I find your approach to a hardware interface to the Skelyak line to be a great help for the users. It would be great if the control box could be

        Re: very low cost USB remote control for ALPY/LHIRES etc I've gotten mine to work via a Raspberry Pi and an add-on relay board. It's connected over my home wifi network and is activated using a simple Visual Basic

        Re: Taking a Flat Thanks for that Robin. The wavelenght center is H alpha. Enclosed a flat of a tungsten lamp placed in front of telescope tonight, there is still the shadow in

        Re: Taking a Flat The diagonal shadow in the bottom right hand corner is strange too. I suggest comparing with a traditional flat taken with a Halogen lamp ahead of the scope

          Re: Taking a Flat [1 Attachment] Hi Marco, What wavelength range are you looking at here ? The main thing about a flat lamp source is that it has a smooth spectrum in the spectral range
