Deep Sky Photography彩色相机伪哈勃色处理流程
彩色相机制作伪哈勃色，必须要包含双窄带滤镜拍摄的图片，如：optolong L_eXtreme，它可以分离出Ha + O3的信息，当然，如果有Astra C1(Ha+O3) 和 Astra C2(O3+S2)滤镜组，后期分离的效果会更好一些。具体处理步骤如下：siril：去星，分离色彩通道为：R、G、B三色图，哈勃色重新合成：运用像素数学获得：中值图 M = (R+G+B)/3, O3=G+B, S2=R-M；再运用RGB合成：Red=S2, green=R, Blue=O3;背景平衡；去除绿色噪点；topaz denoise ai：去除目标和背景的噪点；PS：拉伸目标与背景，哈勃颜色增强调色，修补背景，制作哈勃颜色滤镜；siril：目标、背景与星点二次合成；topaz gigapixel：提升解析力；
Seestar Official GroupHas anyone else observed the Seestar is not able anymore to take images for a mosaic in EQ mode?
So far I noticed already twice that my Seestar stopped taking images for a mosaic of the Flaming Star nebula. It worked well for about 40 minutes, after that all images were refused with the error message referring to startrails. It was around zero degrees, the Seestar was set up for EQ mode. In those nights the Flaming Star nebula was above 65 degrees and unobstructed. No clouds as well. When I switched to other targets the same night without changing my setup everything worked as expected. I wonder now whether it is an issue with the Seestars motors in the cold when trying to shoot targets above 65 degrees? Has anyone else observed something like this?
Seestar Official GroupLooking for option to set and change exposure duration in plan mode?
Hi. i am looking for the option to change the exposure duration per target in plan mode. For example, first target 10s then second one 20s etc etc? is there such a thing? Do not even see how to set it for the first one :( I can not find it :( thank you
Astroimg Official GroupAOE 5 – Skylar’s Nebula (SH2‑132) — A Tribute and a Gift
20 hrs 50 hrs Skylar, my best friend for 11 and a half years. Has passed away , and the silence she has left behind is hard to describe. Wherever I went, she went. Even to work. She was my shadow, my companion, and the brightest part of every day. In her honour, SH2 132, the Lion Nebula, will now be known as AOE 5 Skylar’s Nebula to me. It feels right. She had the heart of a lion. Processing this project was emotional in every possible way. I rage‑quit more than twenty times, walked away, came back, swore at the screen, and eventually pushed through. The final editing time was seven hours and fifty‑three minutes, and every minute of it was for her. The Offer To mark her 11 and a half years with me, I am offering 20 hours of wide‑angle H O S data to 11 people, one for each year she was by my side. Experience does not matter. If you only have a Seestar and have never processed H O S before, that is absolutely fine. If you are an experienced processing expert, also fine. Like Skylar, I will be a little selective, but only in a positive way. I will choose based on whatever feels right. I also have a 50 hour close‑up portrait of the region. You are welcome to ask for it, and I will see. One Request If you process the data and upload it on this app, please title it: SH2 132 Skylar or AOE 5 Skylar On AstroBin, Instagram, Facebook and elsewhere, you are welcome to use the traditional name SH2 132 the Lion Nebula. This is my way of keeping her beside me for a little longer. Thank you for reading, and thank you to anyone who wants to give Skylar’s nebula their own touch. Stuart Oh and the stars aint ai'd or added , I used a mask write skylar applied and brightened it . Oh and @天文知识馆 the office staff is more than welcome to have data aswell
Planetary PhotographyMoon in this morning
Well seeing at the morning and clear moon get. #Seestar S30 Pro#
Seestar Official GroupThis is already a cry from the heart!
I don't understand what's going on. With absolutely clear skies and no wind, the telescope can't create the stacks of objects that the filter is used for. It spins for 10 minutes, and in that time, it only accumulates 10 seconds. This is the third object it's refused to photograph this evening. I'm extremely outraged, because there are no objective reasons for this behavior.
Astroimg Official GroupWhat is a star coin? ?
Does anyone have any idea what a "star coin" is? You can supposedly give them to people under the "support an image" button. I have no idea how to get them either besides someone giving you one, but then how would they get one in the first place? Definitely a new feature, I have never seen it before. I haven't seen any descriptions of it anywhere on this site or the seestar app.
