July 7th - Ha
Hi everyone...
I had a brief amount of time on Saturday to grab some images, but the seeing was poor so I limited the session to a few full disk images and cut attempts to do any higher resolution work based on how things shaped up on the monitor when I set up on the CR150.
The images below are a composite disk and limb exposure, with the limb layer inverted to enhance the small, faint proms on the eastern limb. These were taken through the LS80T/B1200Ha/LS75FHa double stack system: With the new suspected AR starting to round the limb I was hoping to get more images but seeing limited me to these...both through the CR-150/DSSII/B1800Ha modded scope and a 2x tele-extender. The first had the pressure tuner of the DSII set a 0PSI which acted like a red filter (WL), while the second was set at 17PSI to put it on band for Ha: I also cut the session short as I found the etalon wasn't properly aligned and I had to dismantle the modded setup and re-build it...which seemed to fix the issue but used up my time so I closed up for the day.
Questions and comments are always welcome,
Brian

Good shots! The new active region seems more of a decaying old one to me...

Re: July 7th - Ha
Brian,
I always like your full disks. Can I ask what was wrong with your etalon? How did it become misaligned and how did you correct it ?
Best wishes,
David

Re: July 7th - Ha
Yes, I agree, I think this big AR is very decayed and holds no sunspots. Just pretty in CaK and Halpha for the plage disturbances. Some lovely images Brian

Franco, Mark, David, and Alexandra...
Thanks to each of you for your comments and feedback, it is always appreciated
David, I had removed the DSII etalon from my modded setup to test out a few things, but when I reassembled it I had not seated properly in the holder and since it wasn't square to the optical axis it wouldn't tune.

Re: July 7th - Ha
Nice images, Brian. Now a few days on, the disturbed plage looks pretty impressive.
Hope you get your equipment back up to par shortly.
