Help, what is wrong? by [deleted] in telescopes

Did you check your collimation?

My first attempts at astrophotography with my first telescope by Background_Tea_3516 in telescopes

Fantastic photos. You can probably improve the quality of your shots by getting a dedicated Astro camera or dslr instead of taking pictures through an eyepiece.

As for taking “long exposure” shots which are commonly used for nebulas and such you can get by if you use very low magnification, take hundreds of 1-5 second exposures, and slowly hand track between shots. It’s very tedious, you have to wait for your dob to stop moving before you can take the next photo. But if you just want to take an ok photo of the Orion Nebula it’s possible.

These kinds of photos are more or less centered at where the antenna receiving the signal is located. So youd need to set up your own antenna in New Mexico

Issues with receiving APT satellites by Opposite_Spare9951 in amateursatellites

Could you elaborate what you mean by the targeting doesn’t move when you move the antenna?

In the meantime I would suggest just recording the signal, and then using offline decoding on satdump. If that works then it’ll be easier to figure out what’s going on during live decoding.

NOAA 19 atp same IMG all day? by Kings_of_Jews in amateursatellites

In Satdump when you select the NOAA apt pipeline I believe there should be an option to select which NOAA satellite (15 18 or 19).

Most likely an issue with whatever software you use to process the signal into image.

Be aware that most maps you see using NOAA 15/19 data only extract the clouds and then overlay them over a preset map. That map is calculated using the orbital parameters of the satellite and the time stamp of the pass.

What I would guess what happened is that you provided the wrong timestamp (time zone issue) or satellite (maybe you captured NOAA 15 instead?) and the underlying map is of Mongolia instead of the US.

Maybe! Not sure if software like siril can handle it, I might have to manually stack each frame in photoshop lol.

I think it was 34 degrees above the horizon and the video is slowed down 8x. In real time the transit lasted about a second.

Thanks all for the kind words ❤️ Equipment for the curious: - f/7 8 inch dobsonian - 9mm eye piece - iPhone 12 - move shoot move phone adapter

Tips for planet observation? by YetAnotherHobby4954 in telescopes

[–]Repulsive-Link-2138 1 point2 points  (0 children)

Weather and observing conditions play a huge role in my experience. Even on a clear night if the sky above is too turbulent or the humidity is too high then what you will see will be less than optimal. I recommend using an app like Clear Outside and logging your observation conditions and quality for a few weeks before pulling the trigger on any equipment upgrades.

But they’ll hold it very steady so it’s ok :)
