Re: FD images taken on March 7, from 540 nm to Ca K / Alluxa and Altair filters
The image is great!
1、Alluxa 0.14 nm + 0.37 nm image K1 or K2?
2、How much bandwidth is required to see CAK Fibers on that disk?
Thank you for your reply!

Re: 3.3 Sol'Ex Spectroheliograph CAK/HA QUARK CAH/HA
I don't have much experience with spectrometer photography; Used for less than a month.
Single frame shooting, sunny weather, low gain and exposure, will the image improve?

Re: Question about QUARK CAH bandwidth?
I am sorry to say this curve from DayStar white paper is completely wrong. It is impossible to have a material (mica, fused silica, or whatever) giving a curve like this. The best possible fit is to have an index of 1.96 for the etalon gap, which is very far from the 1.65 index of mica. See more in...

Question about QUARK CAH bandwidth?
Hello everyone:
The QUARK CAH manual mentions a focal ratio>=7 and a bandwidth of 5A; The white paper mentions the relationship between focal ratio and bandwidth;
When the working focal ratio F36-F48 (>F30), what is the approximate bandwidth of QUARK CAH?
Thank you for your reply!

Re: HR Ca K images with single/double/triple stack Ca K Alluxa filters and top seeing / 29 sept
Dear Christian Villarich:
The image is great!
Seeing your single/double filter comparison chart, it indicates that CAK,CAH Spices on the disk have been detected. What is the required filter bandwidth< 1A, can a single filter be used?
Thank you for your reply

Finally, the astrob. in image can be seen,
Is CR6 full caliber or reduced caliber occlusion? What is the bandwidth of Alluxa?

Dennis has great details! Amazing!
The first photo: AR3057 camera is 432, assuming Barrow is 3X, and the image sampling is only 0.26; But C9.25 has a resolution of approximately 0.35 at 393nm, does the image drizzle 2-3X?
