I've been away in Brazil this last week (I get to travel with work), we're doing some work with a shipyard south of Sao Paulo, at about -23.8 deg and 48deg W. This is the first time i've been in the southern hemisphere.
And yes...you guessed it - it was mostly cloudy at night (the astronomer's curse strikes again). I did get to see Sirius directly overhead on Thursday night, but no southern Milky Way or Magellanic clouds.

Avian Starseeker first light.
Really, this session started out as no more than a quick test of the telescope with the camera.
It wasn't a particularly good night (6th March) so i was just hoping to see what I was going to need in the way of extension tubes to get a good focus with the camera. I put in the 75mm extension tube and pointed the scope to a brightish star (Betelgeuse), and used Maxim to take focus frames while I found the focus.
As it happened that didn't take as long as I was expecting so I decided to have a go at something not too tricky as it was a mediochre night.
So I slewed over to M35 and took 5 off 30 second exposures in each filter followed by 10 flat frames in each filter.
When processed I got this....
...which isn't bad at all, so all in all a successful night and a reasonable first light image.

It arrived
The Avian Starseeker arrived today after a failed attempt yesterday.
Need to try it out on some good skies, but it feels like it will be a good investment.
