July 7th - Ha
Posted: Tue Jul 10, 2018 6:54 pm
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
