Re: QUARK 9.9 HA full diak and prominence

Hi, Alex

My favorite is your first prominence image. Well done.
What does the 9.9 in the title mean?

A variety from Sept 16 (with Gates of H*ll image)

It seems that this year the time between acceptable seeing sessions is longer than previous years. The following were recorded just after noon local time and 2/3 of the files were rejected but heavy processing salvaged a few. All files were taken with an LS152 double stacked with a Quark Chromospher...

Proms and AR from Sept 12

I set up a seldom used scope for this outing knowing that, again, higher res imaging would not be possible. The single stack setup consisted of a Baader 135mm ERF in front of an ES 102 scope with a Baader 3X telecentric + Quark Combo + tilt adjuster + Blackfly camera. The combination seemed to be a ...

Proms on Sept 7, 2018

Despite waiting and waiting, the sky never cleared enough for any high res imaging. Clouds, either thin or dense were always passing in front of the sun with small breaks. The image below was taken with an LS80 + Baader 3X telecentric + Quark Combo + 5Mp Blackfly,

Re: Filament and active region on Aug 15

Thanks for the views and comments, everyone.

Hi, Valery.

These images were taken in somewhat hazy skies using a Lunt 152 doubled stacked with a Quark Chromosphere at 3800 mm (f/25) on a Blackfly S camera (5 Mp).

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...

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).

I'll be looking for some "tufts" of activity later today (July23) and I hope the proms shown on NSO/GONG survive the wait.

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.
