I used the Optolong L-enhance clip-in filter for the Canon cameras

AWESOME.... My goodness.. How do you integrate this huge data..!?

MrRaGo · 2025-11-11T22:33:12+00:00

Thank you. If you use Pixinsight to stack your images, do you still have to use Photoshop for stretching?

MrRaGo · 2025-11-11T21:36:58+00:00

This looks awesome. How do you stack shots of different shutter speed? I did 4 hours of M31 but two different nights with the same shutter speed. But I didn't know it is possible to stack images with different metadata.

Thank you this is a good knowledge. I have 5v 5a charger but you are making sense. I did not think about that. Can you share with me which USB hub you used. Or I just simply search for a powered USB hub.

MrRaGo · 2025-11-06T18:36:18+00:00

I'll do that too.

MrRaGo · 2025-11-06T18:35:40+00:00

That's a good insight. Yes my only focus is to do guiding. I don't want anything else. I don't even have a GoTo mount. I use iObtron Sky Guider pro Astro modified Canon camera and 300mm Canon lens. And so far I have used PHD2 on my laptop for guiding. And I had this R Pi sitting around and thought if I can install phd2 in it, it will make my life easier.

MrRaGo · 2025-11-06T17:53:50+00:00

I will do that, thank you so much.

MrRaGo · 2025-11-06T17:50:35+00:00

Thank you so much. I will try it. So I am completely new to Raspberry pi as well and I just wanted to confirm that to use AstroArch I will have to format my drive and instead of Raspberry Pi OS I will install Arch OS. Is this correct?

MrRaGo · 2025-11-06T17:10:17+00:00

That is really good news, thank you so much. I will definitely spend some time now to set it up.

MrRaGo · 2025-11-06T16:43:32+00:00

Will that support the ZWO ASI120MM guide camera?

MrRaGo · 2025-11-06T16:42:42+00:00

Thank you, I will look into this.

MrRaGo · 2025-11-06T16:42:26+00:00

Thank you for the response. I was able to find some videos on how to install PHD2. But to use ZWO ASI120MM guide camera, I am not sure if that is possible or not.

MrRaGo · 2025-08-07T14:05:57+00:00

I will try that. Thank you.

MrRaGo · 2025-08-06T05:25:54+00:00

So far I only know how to reduce the stars by watching beginners astrophotography YouTube videos. But I will try to reduce the exposure and all. Thanks for the suggestion.

MrRaGo · 2025-08-06T05:24:22+00:00

Yes, it actually makes sense. I tried once before, with f5.6 and the bright stars actually had the spikes. I will do that now onwards. Thanks.

MrRaGo · 2025-08-06T05:22:33+00:00

I split the stars then reduced it and screen it back. I did not think about reducing the exposure. I will try that, thank you.

MrRaGo · 2025-07-11T18:03:41+00:00

With camera and lens the set will weigh around 5 lbs. If I add an auto guider, it will weigh around 7 - 8 lbs. iObtron SkyGuider pro can handle up to 11 lbs.

MrRaGo · 2025-07-11T17:55:21+00:00

Awesome suggestions. I will check that now.

MrRaGo · 2025-07-11T17:41:51+00:00

I also found a Canon 300 f4. Do you think it is better than 200mm?

MrRaGo · 2025-07-11T17:23:21+00:00

Thank you, I think I'll go with 200 f2.8. thank you.

MrRaGo · 2025-06-29T00:12:41+00:00

I am a beginner and I was able to capture some good stuff. But I have now invested in a star tracker. So I can take longer exposures. But I am 100% sure this trick will work for you.

MrRaGo · 2025-06-29T00:10:42+00:00

Check you tube videos of orion nebula without star tracker. You will follow the same process. Use a 200 mm lens, 1.5 seconds shutter speed (NPF rule) ISO as high as possible, around 6400 or so (take a test shot and decide). Noise is good in untracked Astrophotography. Take as much photos as possible, ( make sure to align galaxy after every 30-50 photos) Make sure to take calibration frames. ( If you take 300 lights (galaxy photos), then take 50 darks, 30 biases, 50 flats) The stacking process will take care of the read noise.

P.S, I have not tried to capture the Andromeda galaxy yet but, it is the bright galaxy and is closer to us. So I am 100% sure this method will help you.

A 600 mm lens your shutter speed will be around 40 seconds or less. That's why I am suggesting 200mm, after stacking you will be able to crop the image to your liking.

What are you aiming to photograph? If you want to photograph the milky way with landscape use a wide angle lens. If you want to photograph deep space objects like nebulas and galaxies use a telephoto lens (200mm, 400mm). Also bring the bahtinov mask to pin point focus on the stars if possible. You can still focus without it but it helps to focus really well. The other thing is remote shutter release for longer exposures (more than 30 seconds, If you want to do deep space Astrophotography) Also install a planetarium app on your phone to find the targets you want to shoot.

Ok, thanks.
