Solar Eclipse Newbie Questions

[RussWest61]

I am brand new to solar eclipse photography and am trying to do thorough research in hopes of getting nice photos of the April 2024 total solar eclipse. My equipment setup will be as follows: 1) Nikon D7100 body, 2) Sigma 150mm - 600mm 5.6 telephoto lense, 3) white light filter, 4) Sky-Watcher Star Adventure 2i tracker, 5) manfrotto tripod. Have following main questions:

1) Since I most likely will be setting up during daylight hours the morning of the eclipse, is there an android app that allows accurate polar alignment without the ability to visually see Polaris? If not, is there another method?

2) Need explanation of the terminology used for the Eclipse Feature column in Dr. Fred Espenak's solar eclipse photography shutter speed table. For instance, Partial - 5.0 ND, Corona - 1.0 Rs, ...? With the fastest shutter speed of the Nikon D7100 being 1/8000 I was planning on using an f/stop of f/11 and bracketing.

Thanks,

Russell West

I've been a member of DPreview for about 20 years, though I haven't typically hung out in the Astro forum. Are you village troll?

Oh wow, you've been a forum member for 20 years!?! That must mean you're right! For how could someone who has been talking about "metrics" like microcontrast, rendering and 3d pop for so long be wrong when they just use the sharpen filter in photoshop repeatedly. I'm still waiting on your raw file, lets seen the before and after. we all know why you are unwilling to post it.

I used an 80mm 600mmFL scope for this shot, not a 100-400 mm lens.

pay attention to the thread, dsjtecserv, the guy you're white knighting for did.

Stacking is done to reduce noise and boost the signal.

I know what stacking is. given how people refuse to post their raws, show that they're so heavily edited that they would even make ken rockwell think it was too much. And pic related, the limb of your sun is full of anti-aliasing in some parts, and others just pure noise surrounded by a blurred area. a 600 f/6.3 isnt impressive, and you certainly didnt capture solar granules

You wanted a raw here's raw from my 10 year old Canon 70D that I used to take this shot. No adjustments just convereted to Jpg.

I'm still waiting to hear from you how much astroimaging you've done and how much solar imaging you've done.

Congrats on posting something not embarrassingly processed, still isnt a raw though. Seems like the guy you were white knighting for abandoned this thread.

Taking pictures of the sun is difficult now?

Dude, clearly your are just trolling, have nothing substantive to add, and have no clue about any of this. No one is going to respond to you any further.

Sheesh.

This is a raw SOOC. Since You can't post a RAW here, all I did was convert to JPG no processing done. But since you appear to be nothing but a troll with no contributions of your own, I'm done responding to you.
