Some long FL Ha from the other night

Shot a couple of weeks ago Friday night as it was a night of very good seeing in Sydney.

Got the motorized focuser now sorted out on the Mewlon 210. Guiding is still a bit iffy. I'm seriously considering using the AO on this one but I have to work out the spacing and back focus available.

Also got caught out on subs direction. 10min is too short. It was very noisy so I'm going to go for 20min next time at least.

I superimposed the pics to older Hyperstar shots showing the native FOV of the Mewlon in context.

Shot with a QHY9 and Baader Ha 7nm.

Enjoy the views.
