3 more Jupiters from Thursday morning

[Pete Presland]

Three more from Thursday morning, it isn't until I uploading to here I noticed how different the colour is on each of the images. Surprising considering all were done with the same workflow. Also the image scale does look slightly down from last April images. Taken at 5.19am, 6.11am, 6.29am.

Think I need to do a little more research/homework regarding my processing techniques. At least there is no shortage of cloudy weather to practice!

C9.25/ASI120mm +x1.8 Barlow. 150secs per RGB channel. Stacked in A/S2, de-rotated in Winjupos, lightly sharpened in C/S2.

Got some good detail coming through Pete. Night and day from last week  There is a colour difference. when you take your RGBs are you checking the histogram live of each channel before you capture

[Pete Presland]

Yes I try to keep them all around d 70% there some slight variation,  I thought the RGB  alignment would get them all pretty much the same. 

[neil phillips]

I don't know then. looks like your getting tons of variation there somewhere.  I would want to know where  that is happening or your colours may always be off

is messing in winjupos causing this perhaps  especially gamma with the LD  values

When you say RGB alignment, if you are refering to "RGB align" in regi then that will only align the various colours up, down, left and right on the image. It will not change the overall look of the colour of the image. "RGB balance" will impact on the overall look of the colour on the image.

Sorry I meant RGB balance 

[Freddie]

No problem. They are very similar terms so easy to get mixed up.

Good to see you out there plugging away. Hopefully conditions will improve to something you deserve for your efforts. I'm too lazy to get out of bed!!

Looking good Pete!

Well done, way more detail than I have managed so far.

excellent image,

Have you compared 120mm to 174mm or 178mm, besides pixel size, sensitivity would be of interest?

No I haven't thought about a new mono camera, but I did get bought a ASI224mc OSC for my 50th birthday last year. Don't tell anybody, but I think I prefer the extra work with the mono cameras!

I had another go at the colour of these images. Combined in Winjupos with the default settings, then RGB balanced in Reg6.

 I think they look a bit better.

Do you disassemble every time your gear or you have it permanently fixed? C9.25 is excellent scope and manageable when it comes to portability.

Did you not use to have C11 as well?

[Pete Presland]

Yes I have disassemble when planetary imaging. I do have an observatory, so there are no cool down times really.

With the planets though, my fixed position wouldn't be any use most of the time. I have very high conifers close by in the south and south/east. Which means Venus and Mars are only visible near my house, which is 20ft north of my observatory. Even Jupiter only becomes visible at around 5:30am to my observatory.

I have never owned a C11, but one would be nice maybe someday

Good work Pete.
