July 29th in Ha

Post by MapleRidge » Sat Aug 04, 2018 12:10 am

Hello everyone...

This past session took much longer to process than I expected, but I finally finished up and have my images from last Sunday (July29th) presented below. Crystal clear skies all day and relative good seeing that lasted until the noon hour helped to make the session run nicely.

The usual setups were used...LS80T/LS75FHA/B1200Ha DS solar scope for full disk and the modded CR150/DSII/B1800Ha scope for the higher resolution images. The PGR Grasshopper Express (ICX674 chip) was used to capture the full disk images and a ZWO174MM was used on the higher resolution images.

The full disk image below is a 2 frame composite of separate disk and limb images (limb inverted):

Disk activity was low but the early stages of AR2717 had started to emerge on the SE limb, and a nice collection of proms made for many imaging targets. First the SE quadrant:

There was also a bit of activity rotating off the NW quadrant as well:

The final images are of the proms...a single frame of the pair of 'eye lashes' on the SE limb and a multi frame mosaic of the group on the NW limb:

A long 'holiday' weekend ahead here, so I'm hoping to have some morning sun and not be called into work on short notice ;)

Questions and comments are always welcome,

Beautiful results, Brian ! Great surface shots and prominences...

I truly enjoyed my visit to Canada, what a great country: it was nice touching base with you.

Alexandra, Mark and Franco...

Thanks for your comments, always appreciated :bow

Franco, good to hear you enjoyed your visit to Montreal and a pleasant surprise when you called too. Your timing was good as about a half hour later I would have been out in the field harvesting wheat plots and wouldn't have heard the phone over the equipment.

Alexandra, thanks I hope we can get some repairs made over the long weekend...the pool deck needs some major attention. Hope the fog burns off and I can catch some sun too.
