What about the exposure time of each frame? I'm starting with a 135f2 or 200f2.8/d850/SA GTI on Orion and i was thinking about making 30 sec-1min frames for 1-2h and collecting shorter frames for very bright parts. Trial or error ? Thx :)
I used a single exposure time of 1 minute. The maximum exposure time also depends on the light pollution. Taking two exposure times of different lengths is definitely recommended and helpful for this object. However, I had no problems with 1 minute. I would definitely recommend not using the maximum aperture of F2 or F2.8. If you have any further questions, please contact me.
@@FelixsAstrophotography thanks a lot :) i will try 1mn then and see the short exposure for the core. Probably 15 sec and blend if it appeared burned. Its appreciated
Do you mean overall “integration” or single frame exposure? If it is about integration, then you need to show differences between 32h, 64h and 128h integrations. This will be more relevant than 1h versus 4h, which is no brainer.
@@FelixsAstrophotography I compared 24, 48 and 72h. There is difference between 24 and 48 hours, 72h doesn’t give apparent benefits. However, if someone is making pictures of super dim nebulae, then I think it will matter. Those pictures are 100+ hours-long and done by combining data from several people. Do you want to do pictures of such objects?!
Tbh, what is the true color? Mine didn't go purple. Sadly I only got a bit more than 1 hour last night. Mine went more orange. My standard camera shows red'ish and yours goes purple.
@FelixsAstrophotography I asked a question, because we now have 3 different color versions. My scope gives orange/red. My camera gives red. Your scope gives purple.
I have photographed the Orion Nebula many times. When I photographed it with my lens it was green. However, most of the images are purple. In the images taken directly from my telescope the Orion Nebula was purple too.
As usual, the longer exposure = the more details. Unless you aren't tracking. My scope suggests at least 2 hours on andromeda, but I want to try 4 hours.
Hi. I took these pictures with F5 and ISO 800. If you use an astro-modified cooled camera that was built for astrophotography then your picture will of course be much better. Which telescope or camera do you use?
@FelixsAstrophotography 1000mm f4 I use t6s, 5dsr, and recently r52. I typically shoot 800iso with the first two (thirty seconds to a minute), shot 600 iso for 5r. I do have access to portal 1 and 2 sky at 10k ft

In every video there is a new learning material. Thanks 😀
Thank you very much. 😊I'm very glad that the video was helpful. What was the longest exposure time you have ever collected of a deep sky object?
You are so creative. It is always nice and interesting to watch your videos.
Thank you very much. I am glad to hear that the video was interesting for you😊🔭
Very useful video thankyou again
Hi.Thank you very much.😊🙏What was the longest exposure time you ever collected of a deep sky object?
@FelixsAstrophotography i do. 120 seconds osc narrowband, 60 sec broadband.
great video!! thanks!
Thank you very much for your nice comment.😊🔭
I m new to astrography and do we need to take video or photo for stacking?
Hi. In deep sky astrophotography we use images for stacking😊

This is about the total exposure time.What was the longest exposure time you ever collected of a deep sky object?

I have also planned a big project for the winter in which I would like to collect more than 100 hours of exposure time.

Yes, that is the original color. That is exactly how I captured the Nebula
@FelixsAstrophotography did you read the comment? 🤔
Yes I did. I hope I understood your question correctly. You asked if that was the original color as I photographed it, right?

Why 30 min is not enough. My scope has 1m mirror and F 1.4 30 min is plenty for almost any object 😀.
Of course, this always depends on the telescope you are using😊🔭
Can you send a link of your scope?
Do you mean my telescope?

What stop is your scope?f32?
I get better 1 minute images than your 30.

You are absolutely right. Light pollution also plays a big role here
@FelixsAstrophotography need to come out to a bortal 1 sky...i would be happy to host and drive you to the sites i use.
