Hi, Ronnie

Beautiful work. The spicules in the second image are striking.

AR moving to the limb on July 18

An uncomfortable day but the AR of the last while is still putting on a show.
The images below were the result of stacked tiffs taken with a Lunt152 at 3800mm + Quark Chromosphere with a Blackfly S (5Mp) working at an ROI of 3 Mp. Excuse the noise.

AR from July 17

On a windy day, with fleecy clouds, and jittery seeing conditions, the following images were caught with a Lunt 152 and Quark Chromosphere.

Re: AR on July 15

This "low yield " session reminded of the days of film photography when you couldn't know exactly how good the image was until your results came back (for slides) and then realized that most of the images weren't worth keeping.

AR on July 15

To give an idea of how bad the seeing was today the images below came from the only acceptable stacked tiff out of 14 . The problem was very turbulent conditions that made sharpening uneffective. The regular setup was used(Lunt 152, Quark Chromosphere, Blackfly S (ROI = 2.2 Mp). Lou ar+.jpg ar-.jpg

Re: July 8th - Ha Session

Hi, Brian

I remember that some of these proms were hard to capture because of their low brightness. I remember not even trying to record some of these. After looking at your images, I should have tried harder.

Hi, Eric For now, my standard setup for these high res views is a Lunt 152 double stacked with a Quark Chromosphere recorded on a new Blackfly S (5Mp) camera. The effective focal length is 3800 mm which seems to be ideal for the conditions I experience here in southern Ontario, Canada. I also have a...

AR continues on July 13

The conditions for the imaging session on July 13 were worse than during my previous post with variable haze providing brief glimpses of the sun at times and other times blocking it almost completely. This is when a fast frame rate camera really shines. At 60 fr/s 600 frames were recorded in 10 s. B...

Re: Ha Full Disk 11th July

Hi, Mark

No matter how few events there are on the sun, I would never be so complacent as not setting up on a clear day to see what's there because, sometimes, the sun disappears for long periods in bad weather.

Re: Is anyone using FireCapture on a Mac?

Hi, Bruce and Alexandra Although I'm Mac oriented, I had to learn the ins and outs of the Windows system when I first started imaging back in 2010 since that was all that was available (to my knowledge) as far as capture software.

AR from July 11

The amazing proms from my last 2 imaging sessions have faded but this AR made a worthy subject on this partially cloudy day. The setup used included a Lunt 152 + Quark Chromosphere and a (a) Blackfly S (5Mp) used with a 4 Mp ROI 307w.jpg 307winv.jpg (b) Blackfly S (1.6 Mp) 25w.jpg 25winv.jpg Lou

Re: Sun from 30th June and Noctilucent clouds

Hi, Alexandra

Those are great looking full disks and prom details.

Do those noctilucent clouds glow because they are catching refracted sunlight or some other reason? I say refracted because you mentioned that you looked an hour before dawn.

Re: Prominences and spiculaes. High Res. Alter to Quark etalon.

Hi, Valery

I always look forward to your inspirational work. These images are exceptional.
I know there may be a reason why you are not giving details about the "alternative to Quark" but I'm sure many people would like to know what this device is even if it is not generally available.

Just before high noon I can assemble my Lunt152 so that it is in sunlight but I can sit in the partial shade of my house for some protection from the harsh sun for a short time.

All images taken with an LS80 + 3X Baader telecentric + Quark Combo + Blackfly S (1.6Mp). This setup allows the full 80mm aperture to be used in a double stack unlike my usual custom of mounting a LS60F in front.
