Hello Solar forum dwellers,

 

It has come to my attention that the pinned “Best of Solar” topic on this forum is quite outdated. I would like to create an updated, more relevant repository of those must-read posts that have popped up lately (and not so lately) that are extremely relevant to the current methods in use for solar observing and imaging.

 

So, I’m asking for suggestions on which topics (threads) you would consider a “must read” (I know there are lots of them, but I’m looking for the “if you can’t spend a lot of time browsing the forum, you should at least take a look at these” type of threads).

 

Let’s make this effort a successful one for the benefit of all us. Please reply with your suggestions!

 

Regards,
Gustavo

I suggest Warren (Rigel 123) post re using the Hinode Solar Guider from June 2019 Very well written with great practical images.

Are you referring to this topic?

Seems I frequently refer folks to these threads, posts, and websites:

 

On site:

 

Etalon Basics

 

Not all filter bandpasses are created equal

 

Tilt tuning Etalon (also has a general etalon formula discussion)

 

I would also consider adding these to the off-site resources:

 

Filter Transmission Profiles

 

Analysis of mica spaced Ha Fabry-Perot etalons

 

Resonant Spaces Part 1

 

Resonant Spaces part 2

 

I would consider adding these online resources:

 

Astrospheric

 

Astronomy Seeing

 

Solar Terrestrial Activity Report

 

Space Weather Prediction Center

 

Gong H alpha Network

 

Observing the Sun in H-Alpha

 

Solar Cycle Science

 

Software:

 

Tilting Sun

 

Indroductary solar books:

 

Observing the Sun - Jenkins

 

Observing Guide to the Sun - BAA

 

Advanced Solar Observing:

 

Solar Astronomy - Viladrich

Thanks for bringing this up, and taking point on it. I'm assuming you prefer open discussion is this thread, as opposed to PMs.

 

Although I wouldn't recommend it specifically for a pin, there was a discussion on eye safety for solar visual and a meta-discussion on the need for a dedicated thread or pinned post. See <https://www.cloudyni...ter-from-china/> and scroll down to get to the meat of the eye safety part.

 

Part of the uncertainty that people may feel here arises from the prohibition of discussion of solar equipment modifications. While understandable from a liability standpoint, it may have a dampening effect on creating a fact-based resource on different wavelength intensities and their effects on human eye structure; and how to construct an optical train of filtration from objective to exit pupil to protect the eye.

 

When I say "construct," I don't necessarily mean "build from scratch" or reverse engineer a PST. As the thread shows, simply placing a film-type objective filter benefits from having additional safeguards down the train. Part of the impetus is concerning presumably rare but possible vagrancies of quality control of a product, and so building in some redundancy.

 

Unrelated, perhaps Bob's excellent list should simply be it's own pin.

 

Again, Thanks.

The suggestions you have provided are great so far. I'm thinking that, for the sake of clarity and ease of search, to divide the threads by topic (actually, not my idea, just elaborating on Bob's suggestions above). Instead of a single list of solar-related topics, we can then divide them by the overarching topic (there may be overlaps). Not all topics may have a "best of" thread, so I'm just putting this list forward as a suggestion. Your opinions are sought, it's your forum after all.

 

Topics to populate with "best of threads"

 

  1. On solar theory and observing (including difference between wavelengths and what can be observed on each)
  2. On solar imaging
  3. On etalons (that would include air-spaced (ex. Lunt) and mica etalons (ex. Daystar)
  4. On white light filtering (solar film, glass filters, wedges, etc)
  5. On safety while practicing solar astronomy (this is obviously in compliance with CN ToS rules regarding dissassembly and modifying solar equipment).

Let me know if this is a good idea (or not), and keep suggesting threads to start building this "best of Solar" compilation!

I'm sorry to see that this post isn't (yet) getting the love and attention it deserves, but I'm really glad you're undertaking the endeavor.

 

I think you have some good stuff to work with, and I am confident it will provide lasting value.

Don't worry, I'm just giving some time to get the thread seen by more people that may contribute but aren't aware of the effort. It's cooking slowly but surely.

I was looking at the best of solar thread a few weeks ago and noticed it was dated, thanks for the effort to bring it up to date Gustavo, all the suggestions so far have merit, and would make good content for the new thread.

Here's one on the Sun in Cacium II K.

Seems like a good idea.

 

Edit: It would be included under the "on solar imaging" section.

The compilation is taking shape. I'm still looking for additional suggestions for the following topics:

 

  1. On solar imaging
  2. On white light filtering (solar film, glass filters, wedges, etc)
  3. On safety while practicing solar astronomy

I'm letting the forum decide what's going to be included, so if you have a favorite thread on any of the topics at hand (or any one of the larger topics list), please chime in!

I would suggest this thread on bringing Coronado Solarmax etalons on band...

https://www.cloudyni...-youre-on-band/

 

This great tip by Bob Yoesle is a great tool and timesaver for Solarmax etalon owners!

An animation video here.

 

Stewart Green's animation tutorial pdf.

 

And Gustavo - here's another possible "best of" - a video featuring Lisa Upton PhD on The Sun, Space Weather and the Solar Activity Cycle.

Thanks Bob; I'm right now writing up the initial post for the upcoming pinned thread. I say "initial post" because I'm planning to add to it as more people continue to share useful additions such as yours.

Team, thanks to your contributions, our new and improved “Best of Solar” thread is now pinned in the forum. Please take a look at it, bookmark it and whatnot, and please keep suggesting the best threads. There’s a couple topics that still need some love.

 

Good job to all.

Hi Gustavo,

 

Great job!  Thank you for putting the new "Best Of Solar" thread together.  

 

We now have two solar animation tutorials, but I think we should add at least one, if not both of these Youtube tutorials, both of which were done by our very own solar friend, Marty Wise.

 

1)  "Solar Imaging Tutorial: Data Acquisition, Alignment & Processing"

     https://www.youtube....h?v=G-41RMTCdTE

 

 

2)  "Solar Processing Workflow, single shot including both the limb and the surface in hydrogen alpha"

     https://www.youtube....h?v=RJvJEoVS0oU

 

Clear Skies!

Hi,

 

Here's the most up to date tutorials of mine that are now short 20 minute videos each (my original tutorial produces a negative image, so I don't use it these days actually).

 

https://www.cloudyni...-jan-16th-2020/

 

https://www.cloudyni...-jan-20th-2020/

 

They are threads with links to the videos since the threads have information in them too. But these cover start to finish from acquisition to processing with mostly free software and common hardware.

 

Very best,
