120mc使用的第二天,M42和木头

本帖最后由 lreach 于 2015-2-17 12:11 编辑

昨天下了多半天的雨

今天放晴了,但有云,架上小黑,插上摄像头,我去,这什么破视宁


小黑+ASI120MC

拍木头前还是直焦M42滴干活,娱乐一下
1.24S*200
暗场6
gain 100
gama 32
DSS + PS 瞎调




4S*200

下面是木头,由衷的感叹一下ai3pro的强大
同样一张图,拿RS6处理出来是烂片(可能是个人技术的原因)
拿ai3pro处理出来却是完全意想不到的效果

3X+二截延长
50%/11000

重新处理一下

摄像头拍深空效果好吗?

不是冷冻的话 噪点会很多
短时曝光还能将就

俺拿这个拍M42只是娱乐一下,而且纯盲跟,极轴对的也不完美,的确不敢长时间曝光。这个摄像头主任务还是月面和行星

真不错!

能介绍下Astro Image的使用经验吗? 你用Astro Image是不是就不用R6了。

我之前有翻出来一个老外的文章,几乎就不用r6

我有AI,但是只是在R6处理后的微调,看不出来明显效果

总觉的用RS6来锐化处理图片,我比较手残。不过ai3pro确实用着比较起劲

我也是这两天刚开始用,以后估计确实不用RS6了

我目前的用法是:
1. 先锐化Wavelet Sharpen
    锐化肯定不能过,而且我觉的还要欠一些,当然也不能太轻

2. 就是依次调节亮度对比度Brightness and Contrust、色阶 levels(这个应该是色阶吧)、曲线Curves

3.就是工具栏上最后一项:Maximum Entropy Deconvolution,啥意思不老懂的,但个人觉得ai3pro里锐化和这个是最重要的
用的是默认的Gaussia,Exponential还没用过,回头试试
Curve Width 和Iterations两个参数不停的试不同的数,直到试到最满意效果
我这两天拍的图Curve Width都不超过2,最小1.1
Iterations从5到18不等

4. 调HSL,个人觉得饱合度调高一点,然后是调Color balance,RGB
    不过颜色始终调不过,所以最后还是要把图放到RS6里,用RGB balance 去auto一下,颜色更正一些感觉

这只是我个人的用法,刚用,还在研究

谢谢经验分享, 写的很详细了。

我刚刚又看了一下老外的经验 (看我以前的帖子http://www.astronomy.com.cn/bbs/thread-291584-1-1.html) ,自己试了一下,终于也发现了一些心得。

目前我的经验是AI处理下来图象会更加细腻,过两天会上图比较。


With 3X drizzle & wavelets in Registax6 I rarely employ anything but #1 & #2 sliders set at "full throttle" (ie, "100") with "Linked Wavelets" checked and Sharpening=0.12, applying De-noising carefully & observing the magnified image with the "Zoom View" window enabled - along with watching the "Histogram" set to "Log Scale".....I suggest you do some little trials yourself with all of this because you can easily open 2 Registax6 windows side-by-side on your screen and with AS!2 opened at the same time you just stack a couple of different stack-sizes/%'s and compare them at the same time in R6 with the same wavelets settings, although as said you might perhaps need a tad more de-noising for the smaller stack - but this isn't inevitable...the smaller stack might have much better SNR and not need any more de-noising whatsoever, despite possessing fewer frames in its' stack (you know what I mean about having two R6's + AS!2 open at the same time, don't try to have AS!2 actually processing as you're playing with the wavelets in R6 - AS!2 is a greedy little bu**#! with processors and likes to gobble up all the efforts of my 8 CPU's..!

(在R6中的处理, wavelet 锐化居然只处理layer 1跟layer2到100%, “linked” 设置)
现在的经验:这个处理的核心在 R6要用“linked” 设置,然后layer 1根layer 2 必须要自己设定denoise, 否则出来的图根本没法看,我之前就是受害者。

Regardless, getting back to AstraImage I usually apply an LR deconvolution at a greater C/W followed by ME at a significantly lesser C/W: this might mean as a rough example atm for Mars on a drizzled image perhaps 3@1.7 @ 1.7 in LR & 5 @ 1.2 in ME or somesuch.....LR is "sharp but vicious" in comparison to ME which has better noise outcomes - the number of iterations with LR is also important to regulate...what you have to be mindful of is not pushing any image in any processing software too far towards the "Ugly Zone"

给出了Astra Image 的卷积算法经验, LC卷积 (1.73次) 然后ME卷积(1.2 5次)
实际处理上这个设定根据自己的图象要有所调整

LC卷积更激进所以噪声控制要差些,ME卷积噪声控制稍好
