Taken this evening [Jan 2] here's a field spectrogram of Nova Vul #2 [=V459Vul] via my piggybacked ETX-70 OTA with homemade focal reducer + Rainbow Optics grating and a field shot without grating. More info on the VS section
I'm pleased with the image quality especially in the corners via the homemade focal reducer that 'speeds' the f/5 OG to f/3.7 and now covers a two degree wide field
Here's a raw field image from last night through brief cloud gap of grav lensed quasar APM8279+5255 in Lynx - quasar not recorded and needs a longer exposure
