Re: Sol from the 11th of August 2018.

Hi, Eric

Your full disks always have a very pleasing gradient from centre to edge. Enviable!

Active region and proms from Aug 11

This was the first decent looking clear day for me in a while but the seeing was very jittery. At least there wetre some areas of interest on the sun. The setup used involved a Lunt152 + 3X telecentric + Quark Combo Chromosphere and Lunt152 + Quark Chromosphere and a Blackfly S (5Mp). Lou Lunt152 + ...

Re: H-Alpha August 10th Lunt 152 - feedback wanted!

Hi, Bojan My Lunt 152 arrived back in summer 2010. I used the scope visually only briefly since my interest was mainly imaging. To my eyes, the image (very bright) showed more surface and prom detail if you looked for a while. I can understand why Lunt recommended neutral density filters. Imaging re...

Sun and moon

The lunar images were from early morning on Aug 5 and 6 with a C9.25 at about 3500mm and Blackfly S with a reduced ROI and the solar image from the end of July used a Lunt 152 with the same Blackfly S with a 0.7 reducer in place with a Quark Chromosphere. Lou 551 copy.jpg 466 copy.jpg 1159 copy.jpg

A new take on the Daystar Interference Eliminator(+more)

Unfortunately, July 23 with its proms was mostly hazy or overcast with no imaging prospects and so I looked back to July 20 with an unposted image when the AR of that day was near the edge. p.25.jpg Also, I came up with what I think is a slight improvement on the Daystar Eliminator.

Re: July 21st Session

Hi, Brian

The c9.25 is the non-Edge version.

Unfortunately, that day our skies were very hazy to overcast and imaging was not an option. Maybe today (July 24).

Re: July 21st Session

Hi, Brian A nice collection of images. Thetre is some very fine detail in the high res prom shots. I'll be looking for some "tufts" of activity later today (July23) and I hope the proms shown on NSO/GONG survive the wait. I'm also testing my c9.25 with a 0.8X c mount reducer in place, mounted direct...

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.

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.

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.

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
