r/telescopes

Taken with a Samsung Galaxy s23 ultra, using 4k video at 1600 ISO. Mounted to a Apertura AD8 Dobsonian. no processing, very light editing to clear things up.

I just wanted to share this photo of the moon which shows its actual brightness. When the earth (in the background) is properly exposed, the moon appears as a dim gray. This is how bright the moon actually is (as I have mentioned before, the moon is only as bright as worn asphalt on a sunny day). When you are viewing the moon through a telescope, it is only as bright as it appears in the image above. It just appears brighter because your eyes are adapted to the dark. This is why moon filters are not needed. The astronaut's view of the moon would have been brighter than anything we observe with our telescopes, and they did not need sunglasses to look at it.

As a counterpoint to myself I will say that moon filters, while not needed, can be nice to have. I have used mine once when I was having a mild headache and didn't want to exacerbate it. And I will also say that worn asphalt on a bright day is actually quite bright, and can make certainly make you squint.

But the takeaway message is that moon filters are a non-essential accessory, and here is a cool photo to show the moon's relative brightness.

Is there any image or test shot from replica or an actual one to see what planet or moon look like through it, given how small it is, I’m curious to see the result so one day I could work with my local carpenter and build an exact replica of it.

Hey guys I got this Celestron Astromaster 70 for my birthday and I’m wondering what lens/ attachments you’d recommend! I’ve got an adjustable lens (7-21m) and it works well but is there anything I need? thank you !

Tried astrophotography with my iPhone and my god awful EQ-1 mount, it looks like a smudge but still better than I expected 💯💯👍👍✌️✌️

What do you guys think about my smudge? And respect to the people who are actually good at this 🙏🏻

Today’s conditions are more than good and even wife decided to join me! 😁 (She does every time actually)

Took this in a huge rush had only 3 minutes to set everything up because I remembered the time wrong 😅

Equipment:

Sky-Watcher 76/700 AZ-1,

iPhone 13 Mini,

Phone Mount

Software used: PIPP, Registax, Gimp

Just got back from a galaxy observing session in which I decided to make a quick sketch of this really stunning pair of galaxies. I am aways a fan of observing multiple objects in the same FOV, and these two really called to me. NGC 4762 was quite apparent and had a lovely shape. NGC 4754 is otherwise pretty boring, but its shape is in stark contrast to 4762 and made for a pleasing combo.

i need a ciggy asap

Acquisition:

480 x 15 second subs for a total of 2 hours

This is my first real attempt using calibration frames. Biases and darks seemed to work fine, and my flats made an effect on the unfortunate shadow of the secondary mirror but it seems I could have done better.

GAIN: 475

Bortle 5

Equipment & Software:

Telescope: Celestron Nextstar 130SLT

Mount: Skywatcher EQ6-R Pro

Camera: SVBony SV305

Acquired using Sharpcap, stacked in DeepSkyStacker and post-processed in Siril and GIMP.

Not yet available for purchase, and details like barrel size, weight, and eye relief are still unknown.

They look quite different from Explore Scientific's other lines. I'm assuming they'll be at NEAF this year. Maybe someone can get a closer look at them there.

The new 92 series does explain why they went nuclear on the prices for the existing 12mm and 17mm 92s. Just needed to clear them out. I'd be surprised if these new ones are as immersive.

Yesterday, I asked this same question and gave like not a very intricate description so I’m gonna show more photos here to answer some of the comments I got yesterday. But a summary is I’m not sure how to get this telescope to work.
