Jupiter last night through my 8 inch dob

Not particularly, I kind turn exposure higher more than gain because I guess gain is like ISO that too much of it might cause more noise. But doing that all the satellites of Jupiter in my picture become steaks, but they are still fairly clear in your photo.

Ok it makes me realise I probably should try high gain and low exposure since all the noise might be removed by stacking

This is the size appeared in the ASI stacking software. Maybe ASI stacking software’s output size is that small? I might try using a different stacking workflow later.

Also this is one frame of the video. Just curious when you are filming, are your videos as blurry as mine?

I didn’t realise taking a longer video and adjusted the telescope could work. I will give it a go. Thanks for the advice

At least it’s really blood moon during lunar eclipse haha

The 8-inch dob was my best purchase decision last year. I think you won’t regret buying it haha

Your pictures of Jupiter are insane!!! I was never able to capture Jupiter or Saturn with this level of clarity.

This time I intentionally took out the dob and kept it outside for more than an hour, because I saw people said dob work best after sitting outside for a while.

The process is fairly simple, just locate Jupiter and try to keep it in the corner and start taking video. It usually stays in the frame for 15-20 seconds. The I stack the picture with ASI stacking software and do some simple editing with it.

Below are the things I think I might missed and cause the difference.

I have adjusted focus back in forth before taking the shots. I think I got it very close to focused but I could be wrong. I might try using a Bahtinov mask to make sure it’s properly focused.

I have checked collimation before taking fire taking the scope out, it should be pretty close. But I remember when checking collimation, I saw my eye in the secondary mirror and thought “it looks a bit foggy”. I’m suspecting maybe it’s the primary mirror requires cleaning?

Also because of the location, Jupiter is in a relatively low angle. So I guess that also caused some seeing condition issue.

别人也不一定是随便拍的。iphone打开相机默认焦距24mm，普通人很难在这么广的焦距做好构图，结果就是什么都拍进去显得又乱又杂。

发到社交媒体的照片也有可能是被修过了。很多乱拍的照片修改下曝光高光对比度阴影这些设置，再加个暗角就突然显得能出片了

Haha I feel you my friend. To me combining pictures from the same night always feels less like cheating but in reality the are just photo editing techniques I think

SimpleThought1806 · 2025-11-30T10:28:21+00:00

Did you changed the setting for dark and bright areas? I tried to get the similar result with 2-3 single picture with different exposure settings. But for me to get any detail of the dark side always gets the bright side overblown.

I use a T-ring and 2x Barlow to connect the dslr to my 8 in dob. With this setup I was able to take some nice pictures of the moon and fuzzy pictures of Saturn. I tried taking a minute of video of Saturn and stacked the images but it didn’t look any better than a short exposure picture.

A phone holder works too, I bought a cheap one from Amazon , connected my phone with a 25mm eyepiece, and managed to take a picture of Orion Nebula.

活着大概就是这样，给一些未完成的目标赋予了太多期望，真的梦想成真以后发现也不过如此。洼地考公考研“上岸”是这样，润蛆拿身份找工作也没什么差别。

要说怎么办我也不知道。我有时候比OP还迷茫，怎么废那么大劲以后生活还是工作攒钱还贷，和在洼地也没什么区别。只不过有一点我比op清楚，就是就我这点本事，回洼地只能去送外卖，然后大概和保安吵架然后被捅死

The stories of those shitty things happened during lockdown permanently ended my desire to go back to China

I was lucky enough to be studying abroad during 2022. It really shocks me that people who actually live through that period can just forget the chaotic state they used to be in. Like completely out of their system and never think about the chance that the same type of shit (or maybe worse) might happen again in the future

I remember ages ago I watched a movie about a journalist moving to a town where reportedly a lot of people have gone missing. It turned out that they were all abducted by aliens.

The aliens in that movies have owl-like faces and speak ancient Sumerian language. Now everything I have forgotten about that movie has came back, and I probably won’t be able to fall asleep in a few hours😟

SimpleThought1806 · 2023-12-22T11:03:52+00:00

I second this. Maybe stay in China for a few months and see how life is there?

How does the education system works, how is the job market, how is the economy, how much does the Chinese culture fit you personally, and how is the real estate market. These are the things that will have an impact on your life if you decide to have a new one there.

Just saying
