If you can measure a prom to 5 figures your ruler is way better than mine.

Thanks Kent. That gives me a third way to estimate height. Bearing in mind that photocopies never come out to original scale and computer images may or may not scale. I adjusted the image to fit my

Here is my rather crude attempt to capture the solar prominence with my 20-year-old H-alpha scope. The visual view far exceeds this rather so-so picture. I was trying to balance the telescope with a

We estimate very close in height. I did not do the length.

Roy what do you figure? 62,137 miles high. Now that is using a scales superimposed on the sun as a guide but I think I am close.

Largest for months – it’s curved over back toward the solar disk, about 45K miles tall, 100K miles long. See it on Gong too:

Thanks Mark. I know someone (Kent) that has the same eyepieces I have and will see if he will join in for the test. [email protected]> wrote:

I can bring my pair of Denkmeir bino viewers. I will have to find the barlow that goes with them but am pretty sure I? know where it is. I don't have eyepiece pairs though.

Might be a good idea to borrow a pair and try before spending money. ________________________________ Sent: Wednesday, March 12, 2025 11:02 AM To: [email protected] <[email protected]>

Thanks for the info Mark.? I was looking at the William Optics version but began researching and was trying to understand if it was worth the reach.? I have seen a lot of posts from folks stating

So, I am interested in getting a binoviewer to use with my scopes.? I have been reading about some issues that one would have to contend with when using them such as: 1.? Image resolving at high
