I did some Ha with a SMC Pentax-M 35mm since Friday trying to get some data on the Eridanus Bubble which turned out to be very hard to get from the burbs as it's so faint. I did nearly 5h on it so far and it's just starting to come out of the sky background. It's the first time I've been considering doing some Ha from a dark site.
Anyway I attached work in progress along with some widefield I completed around Ara. There are a lot of familiar nebulae, SN remnants and clusters in the field.
There are bigger versions below:
ARA widefield with a 1:1 version if you view the original
Plate solve is
here. Again click 'view original' for 1:1.
Eridanus Bubble widefield - There is an old version of the barnard loop next to it for size reference (same FOV)
The 35mm is not a bad lens on axis. It has to be stepped down a fair bit though and there is still some residual coma. Can't complain for the price.
Thanks for looking and enjoy the views.
