You’re doing a wonderful job with that Lunt Paul.
Very nice details. My favorite is the first image

DavidP

Very nice image Ivan. Congratulations on the new set up.
I am impressed you can get 7ms Exposures with low gain using the etalons.
Does that require removing any filters in them?

DavidP

Nice images, Marty.
I especially like the calcium images without color added

DavidP

Thanks folks, I am really impressed by the amount of detail it's possible to get with the Lunt 60, this was imaged at ~0.71"/pixel. I'm now thinking about a "Marty mod" for it (https://solarchatforum.com/viewtopic.php?t=34331) and I can see a Lunt 100 would make an ideal retirement g...

DavidP

Very very nice.
Wow. F/100. So it turns out you can double up telecentrics. What was the final focal ratio?

DavidP

Thank you all. It was fun to get out look at the sun in detail.
The AR3634 image didn’t transfer very well.
Here’s another attempt (low res jpeg)

These are wonderful. I’m glad it worked out.

After months being down, I finally got my mount back up and running. Here are a couple of white light images. I did the last couple of weeks. Orientation is not true. This is AR3615 for Allen with a 150mm and a Continuum filter. IMG_1208.jpeg This is AR3634 from 4/14/24 with a 9.25” and an OIII. Not...

DavidP

Congratulations. Very well done.
Can you explain the “tilter and shifter in the second part adapter”? Do you have any images of this?

DavidP

Those are outstanding images Christian.
Alluxa quotes just 1-2 weeks on these

DavidP

Any links to images or experience with one of these?

DavidP

Absolutely top-notch images!
You should be proud of the images and the telescope you have created.

These are aesthetically gorgeous images Dennis.
AR2615 has been amazing

DavidP

Beautiful images Nic with very nice detail

DavidP

Very nice images and comparisons Christian.
I am unfamiliar with the term “visualization thresholds”. What does that refer to?

DavidP

That prominence!

DavidP

Just stunning images Stuart.
So well done.

DavidP

You might contact Bob at Alpine Astronomical about availability

DavidP

Thierry.
Those absolutely stunning images.
I have never seen a white light video equal to that.

DavidP

Very nice images.
Especially like the high res white light.
Well done

DavidP

Nice work, Brian
I especially like the HA mosaics.
With Ha etalons there doesn’t seem to be quality guaranteed no matter how much you spend. My Solar Spectrum RG isn’t very uniform.

DavidP

Your second image is, indeed, excellent. You did a very good job of processing it.

DavidP

These are some very good images, Michael. I’m guessing they were taken with your Lunt and that it’s double stacked?

DavidP

Thank you Mark

DavidP

Beautiful image. It was done with your SCT, right?

DavidP

Is my blocking filter vignetting? My understanding of how this works is not great. So I have a 50 mm Lunt mod that I use on a couple of different telescopes. The first set up is: 2350mm fl + 4x TC + 50mm Lunt+ .4x 2” reducer. + 1200 blocker + 14x10mm chip The other is : 1500 fl + 4x TC + 50mm Lunt +...

DavidP

Welcome to the forum!
These are gorgeous images. Looking forward to more.

DavidP

Michael. Those white light images are stunning.
We all dream of creating such images.
Congratulations and well done

DavidP

What does “unity” gain mean?
I understand “gain”, and understand “unity” as an expression of 1.

DavidP

That is a stunning animation. Well done

DavidP

That is a stunning animation. Well done

DavidP

George. It’s just fantastic what you’ve been able to do. Very inspiring.

DavidP

Nice images. I also like the granulation in the second.
And with a Mak!

DavidP

Very cool.
Thank you for putting that together

DavidP

Very cool.
Thank you for putting that together

DavidP

These are wonderful, Eric.
The prominences on the limb images are wonderfully sharp. Are they separate images combined with a surface image?

DavidP

Absolutely fantastic!
My favorite animation of 2023 on the last day of the year!

DavidP

I feel, Valery, that no one here disputes the theoretical fact that the angular resolution increases with the diameter of the mirror. But as usual, the theory applies to the ideal state, but in practice other factors are applied that influence the result. Agreed. No one doubts the resolution apertu...

DavidP

That solar disk is stunning. Nice work.

DavidP

Wonderful images Leo. I also really like the second image a lot. The angle of it provides a lot of information.

DavidP

I agree that a 200-250mm would have a greater market. I do have an interest though. And it seems that continuum and Ha would be more realistic to make use of such a scope. Getting consistent solar seeing of < .3 arc” to properly use the scope for Ca K is in reality a rarity on the planet. In answer ...

DavidP

You do such a nice job of processing Stu

DavidP

Wonderful animation. Well done.
The spicules on the limb are mesmerizing.
I love how it also captures the suns rotation.

DavidP

Yes! This discussion has help me tremendously.

DavidP

I’m very impressed with what you can come up with in poor seeing conditions.
Are the surface and proms combined from separate stacks?

DavidP

Wow is right!
Nice captures

DavidP · Re: Almost an X Class 11/28/2023 Very nice disk Simon

Very nice disk Simon

DavidP

Congratulations Warren and Simon. These are so exciting to see. It looks like, indeed, there were a series of CME‘s. It appears like we might get some nice auroras for those of you lucky folks living up north. https://www.earth.com/news/noaa-alert-strong-geomagnetic-storm-warning-issued-due-to-stron...

DavidP

That is a work of art. Looking foreword to images from it.
