  1. Thanks Dave and Rob. I have this on a possibls hit list if I manage to make my move. Maybe even a sensitive OSC?
  2. It's almost not-do-able from here, but I think @Uranium235 did an heroic mosaic of the rho ophiuchi nebula last year. You need a very low southern horizon and NB filters I think.

    Summertime Imaging

    I found this old thread from June last year Comments suggest it was better than I anticipated.

    Summertime Imaging

    I have imaged in HII during summer twilight, but that was with a 3nm Astrodon filter.
  5. As far as I'm aware there's no evidence that the universe as a whole is rotating.
  6. Looking like a very clear night, but I'm still a bit knackered after a 10hr round trip to Dorset and a good glug of wine so won't be imaging. Might do a bit of mk1 eyeball astronomy.

    FLO & GDPR

    Yes, done as soon as the email came through
  8. Ouch, that's horrible! . Not even sigma stacking could get rid of that. Another reason to take many short subs rather than a few long ones wrecked by planes.

    Using EQMOD to control mount.

    Well, not literally, but you don't need it with Eqmod. In fact my old HEQ5 is a Syntek version (No longer made alas), so I just used one of these https://www.firstlightoptics.com/astronomy-cables-leads-accessories/lynx-astro-ftdi-eqdir-usb-adapter-for-sky-watcher-eq5-pro-heq5-syntrek-pro-az-eq5-gt-az-eq6-gt-and-eq8-mounts.html to connect it to my laptop. I ran Cartes du Ciel (Better for control than Stellarium) / EQmod / PHD2 for guiding, and either APT or AstroArt5 for acquisition. I now run an ASA mount so no longer need Eqmod or PHD2, and use Maxim DL6 for plate solving and acquisition.

    Which Narrow band Filters?

    I've used Baader ones with ASI 1600, though my main set are 3nm Astrodons. You could also have a look at Astronomik NB filters.

    Using EQMOD to control mount.

    Just so. If you're using eqmod then you're also using a laptop, so chuck the handset away and just use the laptop. Cartes du Ciel / EQmod / PD2 plus whatever capture software you're using.

    UV/IR cut filter advice

    Yes, I think you will need it unless your system is completely free of chromatic aberration, which effectively means a RC with no refractive field corrector optics. Only if you go narrow-band can you get away without one.
  13. Yes, especially this time of year. Roll on retirement.

    Is this the death knell for CCD cameras?

    Hmm.. Anyone up for the KL6060. Mind you, I think even a Tak FSQ106 might be pushed to cover the 87mm imaging circle .
  15. My first finder was a home-made job with a 60mm objective and an Erfle of unknown fl that I put crosswires in myself. I didn't have a red dot until I got my Meg90. I had a Telrad but sold it at the last SGL. Now I don't have any finder as I use a sky model and an encoder mount.
