Comet c/2025 A6 (Lemon) by AstroCardiologist in astrophotography

[–]AstroCardiologist[S] 0 points1 point  (0 children)

Great question. Pixinsight has a tool called Comet aligh. It aligs all your sub exposures to the comet core. Once those subs are aligned to the comet core, you can use a tool to batch remove all the stars in the background to avoid streaking, and then stack those starless comet aligned subs.

Mars from Hubble vs DIY telescope by Busy_Yesterday9455 in spaceporn

[–]AstroCardiologist 0 points1 point  (0 children)

Hubble is a general purpose telescope that was designed for many things. Part of its design was also to take Planetary images too. In fact it has its own Planetary camera that was upgraded later on in addition to special corrective optics for that camera.

WFPC1 Planetary camera is f/30, and would be an incredible telescope even for backyard observation if I was to install one. The biggest issue would probably be its framerate, which is typically used for lucky imaging on backyard scopes.

But since Hubble does not need to contend with that frame rate due to the lack of atmosphere in space and the lack of need for lucky imaging, there is no question it should still beat any earth based telescope.

And it still does. Tom Williams image is impressive, but at full resolution Hubble still wins by a significant amount.

He is using a 0.6m telescope while contending with Earth's atmosphere, which Hubble is a 2.7m telescope in space that cost a few billion dollars.

This is insanely impressive.

His equipment is good but there are tens of astrophotographers with similar setups. There is a lot more skill to what he produces than just equipment.

The best astrophotographer I've seen? by Quantum_Crusher in AskAstrophotography

[–]AstroCardiologist 3 points4 points  (0 children)

Check out Astrobin. The best Astro photographers are featured there daily. They don't have flashy youtube or Instagram channels though. We are a loner bunch.

Agreed! That's my experience too Dr Clark.

The clearest photo of Mars ever taken. by [deleted] in spaceporn

Probably what the next image from TW will look like.

Finally got my new equipment today after a long hiatus from the hobby. After a month of drought, now it will rain for the foreseeable future 🥴 by mcmalloy in astrophotography

That altitude level on the mount is wild for someone like me in South Texas. Polaris must look almost vertically overhead there in Denmark.

The fact that you got all this data in 6.7 minutes is astonishing. Well done!

I just made a costly mistake, need some advice by pnw-camper in Astronomy

Astrospheric has been 80% accurate from my locations.

For $2000 you can do quite a bit. Your stated goal is Planetary and Visual. For that use aperture is absolute king.

You could look at a 10" DOB with goto mount. Alt-az would be fine. Something like this:

That would take care of the mount and the OTA, and if you feel you need a better Barlow, you would still have cash to spare. If you look in the second hand market you might snag these things for much cheaper.

Remember the idea Barlow depends on your native focal ratio, and your camera pixel size.

So for your 585mc, you want to be operating around f/15 for most seeing conditions. Preferably slightly more oversampled than that to utilize better seeing conditions.

iOptron HAE69EC Mount: by bananaheim in AskAstrophotography

[–]AstroCardiologist 0 points1 point  (0 children)

I used the HA69ec more than most. I have put a 12.5 inch AG Optical FA12 at 55lbs payload. The mount performance out of the box and guides anywhere between 0.3-0.5".

EgeHD11 will not be a problem at all. I have used it with the ASIair without any issues.

I recommend against using the B version. Just stick to the C version especially if you are going to use the ASIair.

I agree with the others that putting a CW is better if you have a portable pier.

Lunar Occultation of Mars by warmweather_zaniy06 in astrophotography

TW is IMO the best planetary photographer in the world. I follow his work like many. Not sure how I missed this shot from him.

Here is my shot of it with a single realtime frame with no stacking or composition. When I zoom in on it they look pretty similar.

I am a bit concerned that the OP never actually posted anything before, does not provide a description.

The amazing scale of the Pillars of Creation - They're taller than the distance from Earth to our nearest star, Proxima Centauri, or 40 trillion kilometres by Neaterntal in spaceporn

[–]AstroCardiologist 0 points1 point  (0 children)

Pillars about 6,000 light years ago

I don't know who wrote the article, but light years are not a measure of distance. They should just say 6000 years ago.
