Hello Thanks for sharing this information. My Player One Ares-C Pro, does not show the manufacture's offset. So, I will try as you recommend. Thanks
You are very welcome and let me know if you need any help. Is there a reason you are trying to adjust the offset?
@@Hidden.Light.Photography Thanks for your reply. Yes, I think is important to avoid the cold pixels. I am a beginner level in astrophotography so I would like to capture my data as best I can. Thanks
Absolutely! If I may offer my advice, try stacking and processing after a night when you make the change to ensure your camera agrees with the change and is capturing correctly. Ask me how I know 😂 Let me know how it goes and if you ever need anything.
It looks like this video was posted today. Your NINA build is over a year old. I have no idea when it was made. You need to update NINA ASAP.
Let me look into this because I just recently checked as it was weird I haven’t seen anything new and my version I’m using showed as the latest available. Very odd.
Just wanted to update on this. I just checked the Nighttime Imaging N Astronomy site on my phone and it is a much different story. I remember checking after someone mentioned the flats wizard changed since an update and when I saw my version was the same listed in the site I figured I was good. I’m going to attempt the update as soon as I get home from work. Thank you again for bringing this to my attention!
Thank you for the tutorial as I have never known how to work out my offset value. I have an Altair Astro 294C cooled camera and when I got it was advised to set my offset to 30 and I use a gain of 200.
I have just tried you workflow and found that actually an offset of 120 gives me typically 50-75 (1x) min with mean around 450. When i checked using 30 offset my readings were min 0 (6084x) with a mean of 60 ish.
My images always seemed OK using offset of 30, so what differnce in my image should I see now with the new offset of 120? How can I tell if the differnece is showing on my image?
Thank you
That is really good news and I’m excited to hear this helped!! How visual the difference is would depend on the signal to noise you’re getting with sky conditions etc, however, I can tell you having my ASI533MC accidentally set to 30 offset instead of 50 made a HUGE difference. The image came out ok, however redoing the target with the correct offset of 50 made it 100x better. I can’t guarantee the same type of result, but I am confident you’ll be very happy with the difference. Please keep me posted on this as I’d love to hear how it turns out :)
@@Hidden.Light.Photography Thank you, Tony, I'm really excited. I'm just retaking my dark library with an offset of 120 now so can use in my new images. I could not find any recommended offset for my Altair Astro 294c pro cooled, so hoping this new offset is a game changer.
Unfortunately, we have really light skies now here in the UK, so waiting til possible late September, early October to start capturing some data. I will let you know how I get on when I have some new processing results. Thanks again, take care and clear skies!
😀
Very good! Yes, please keep me in the loop of how the change affects your image quality. I’m excited to hear from you :)
I have a OSC 2600MC. I would shoot this with my clear filter and I assume I would repeat with my NB filter which would probably require a different offset. Correct???
Always use the same offset. I highly recommend using the manufacturer's offset.
Going off of Jim, the offset would remain the same. Offset is just preloading the pixels to set your black point. The only reason you would do this with a different filter is if you are using a different gain. Gain can affect this so if you change your gain you want to run through this process to make sure you don’t get any zero value pixels.
The factory offset setting works just fine though and is set very well from the factory, so you would be just fine using the factory gain.
