August 15th - Ha
Hi all...
A short session yesterday (Aug 15th) which only gave time to collect a few FD images with the LS80T.
The first shot is a composite of separate disk and limb frames (limb inverted), showing the rather bland disk, but a nice prom on the NW limb: The second image was obtained as the first was, but with the LS75FHa etalon mounted on the front of the LS80T to double stack the system. A few small filaments on the NW and SW quadrants show a bit more in the DS image, but the prom isn't as sharp in the longer exposures used in the DS system: I wasn't able to pull any higher resolution images out of the nice prom...exposures became far too long and the seeing washed out the details
I'm hoping for some clear skies with better seeing on the weekend, but really need rain or crops are going to be toast soon

Re: August 15th - Ha
Nice disks there Brian, there's a few faint and diffuse filaments knocking around lately which you caught well. Been busy here lately with one thing or another, and, coupled with weather has left little time for imaging. Hoping to get a couple of disks in this weekend fingers crossed!

Re: August 15th - Ha
Lovely disks, Brian. Nice prom there, which you’ve captured very well.
A chance of some Sun between weather systems here, so maybe, if I’m lucky, I’ll get a chance to image later today.

Re: August 15th - Ha
Derek and Stuart...
Thanks for your posts about the images. I was happy to get the finer details in the prom, but would have liked a bit more resolution.
Alexandra has told me about the constant rain in her part of the UK, hopefully it clears off for you all. On a positive note here, I awoke to rain and every drop is needed. So far it hasn't added up to a half inch which doesn't solve the drought problem!

Re: August 15th - Ha
Hi all...
Here are a couple of images taken the evening before the solar images.
Wheat harvest is 3-4 weeks behind normal here, but the dry weather is allowing harvest to proceed. I snapped this pic of my neighbor combining wheat just before sunset, a few solar photons went into producing this crop (sorry for the gluten component Alexandra): On the opposite horizon the full moon was rising: Brian

Brian, great looking disks and detailed feint proms from the LS80. Something for me to strive towards. Do you remember what the exposure times were?
Enjoyed the setting sun and moon shots as well.

It may have been a short session but you got some really nice images to show for it, Brian.
I like the inverted prominences.

Re: August 15th - Ha
Phil...
The exposure data for the images used in the two composites is detailed below. In both cases the base scope was the Lunt LS80THa/B1200Ha and a PGR camera using the ICX674 CCD chip, a ROI of 1400x1400 pixels, and stacked from the best 150 frames from a 500 frame SER file:
Singe stack mode
- Disk image Exposure 3.162ms/Gain 200/Gamma 600, 25 fps
- Limb image Exposure 100ms/Gain 200/Gamma 1,100, 9 fps
Double stack mode
- Disk image Exposure 8.357ms/Gain 200/Gamma 600, 28 fps
- Limb image Exposure 356.4ms/Gain 200/Gamma 1,100, 3 fps
- the DS was made by adding a LS75FHa (front mounted 75mm tilt-tune etalon)
Let me know if you have any questions,
Brian

Re: August 15th - Ha
Superb full discs Brian and great to see the dusty sunset and harvest moon I really enjoyed these a lot
After a dire Friday, Saturday and Sunday weren't too bad, we had a fair bit of sunshine on Saturday afternoon but both days we had gale force winds. All my Sunflowers are at 45 degrees despite me trying to keep the canes upright. I must take some photos

Beautiful crisp FD´s, the proms are super.
At my place just rain and just few minutes to see the Sun through clouds.
Best regards,

Alexandra, I hope you can get the sunflowers standing or at least stabilized...they were very tall when we visited last month so its not surprising that the wind caught them
