The Veil

Had a go at the Veil with the 300mm lens on Monday night, using the Quadband filter and Star Adventurer. 2 minute subs was giving me trails so I reduced it to 90 seconds. The forecast said there was only 45 minutes before clouds rolled in, but they held off most of the evening and I ended up with 111 subs and used DSS to stack the best 70%. It’s needed a lot of processing for various reasons (I don’t think the filter and lens get on too well), and certainly doesn’t stand up to any pixel-peeping, but I’m still quite pleased with it.

changing guide camera on CCDSPEC spectroscope

I have had 2 x QHY6 cameras attached to my CCDSPEC spectroscopy but as this camera uses an ASCOM driver only one camera can be seen by my laptop at a time which means that in order to use a camera as well in the eyepiece port for finding and guiding on faint object whilst spectrums are taken I need to use 2 x laptops at same time (one for spectra and one for guide camera). What a nuisance! Today u have changed the QHY6 camera in the guide port to a T7C camera (clone of ZWO ASI120MC – uses same drivers) and using a 1.25 inch extension tube focused on the spot and confirmed that both cameras can be used simultaneously in my Dell Windows 10 laptop.

  1. QHY6 camera for spectra – take photos with Nebulosity 4 and use ASCOM driver. Camera plugs onto USB 3.0 port on laptop.
  2. T7C camera in guide port on CCDSPEC. This uses ZWO driver and use SharpCap (currently I have version 3.1.5220 installed). This camera does NOT work when plugged onto USB 3.0 port so needs to be plugged onto USB 2.0 port on laptop.

I have also picked up another of Damian’s habits = which is labels over everything!
