July 7th Images

Post by MapleRidge » Sun Jul 14, 2019 1:11 am

Good day everyone...

It has taken most of the week to process the image sets captured last Sunday...maybe a week of 'spring rush' left at work...dragged well over a month late compared to most years with the clod, wet spring. Last Sunday was a beautiful clear day, though the seeing wasn't great it was better than I expected. With the prospect of seeing the new AR associated with the new solar cycle I ducked out to the observatory after breakfast and spent the morning viewing and imaging.

The first set of images are full disks. The Ha was taken through the LS80T/LS75FHa/B1200Ha solar scope and the PGR camera (ICX674 chip). This is a composite image with a longer limb exposure to pull up the fainter proms (limb inverted):

The next full disk images are through the iStar 150mm/f8 OTA using a Lunt Solar Wedge/Baader Continuum filter for the WL images and a modified Lunt Solar Wedge/B1800CaK module/Baader K-Line filter set. Both used an ASI1600MM camera.

While the iStar was on the Sun I imaged the developing AR in WL and CaK with a 3x tele-converter and the ASI174MM camera:

I switched over to the modded CR-150/DSII/B1800Ha and the 3x tele-converter/ASI174MM to see fruits of the Ha spectrum. Initial images did not show a lot of detail, so I swapped the B1800Ha blocker for the Quark Combo to DS the scope, and this made a significant improvement in the ability to see the details. I made a few mosaics of the regions of interest, specifically the developing AR, filaments approaching the western limb, and a small spot of activity on the SW quadrant. The DS setup requires long exposures and I ran the camera in binned mode for these images:

Quite a nice session with the new cycle showing signs of life :o

Now, I think I have some unprocessed prom images...I better see what happened to them!

Questions and comments are always welcome,
Brian

Nice images, Brian, I liked H-alpha in particular. WL and CaK appear quite dark on my screen, they could be improved by using of curves tool or a high pass filter. I tried to do so but some artifacts emerged at the top limb of the full disc. At full resolution CaK is impressive, very well resolved.

That is a super solar harvest Brian, you got some lovely close ups of the new cycle spot and some delicate little pores in the WL shot, well done!

Thanks for all of the comments everyone...always very much appreciated :bow

Raf, I was tempted to adjust the brightness before posting but thought it look like these two specific images would look ok...should have spent more time after all. I had a lot of trouble getting the large CaK/WL images to stack without the artifact, and after locking up the computer on several attempts to redo them in several programs I just used the only attempt that worked.
