Photoshop or Pixinsight?

[RobH]

Sam, sorry, I missed your post earlier.

Thanks for the explanation, I get the idea although I don't like the sound of 'maths' and 'formula'

I could never even get 1+1 to equal 11

Sounds intriguing.

Cheers

And mind blowingly sophisticated... more options that you could shake a stick at...

Hi

Look at my video http://www.harrysastroshed.com/Stack.html

Most of the settings (if not all) can be left default and really very easy to use:hello2:

That's cos it equals 10...

Hi All

No questions today on Pixinsight

I feel all unloved

Everybody has mastered it then

All busy learning, or working (to pay for it)

I notice that the DBE tool auto sample grid function doesnt populate a grid of samples over all the image. Does it try to assess where to sample from automatically?

Registar does a much better job of registering images from different scope/camera combos than Pixinsight... discuss...

Hi

The new DBE tool is different from the old tool in several ways

It will try to put samples on area with little signal ( IE not on your neb or galaxy)

It some times fails to do this if you have large illumination differences ( IE no flat frames ) or a lot of light pollution gradients or the image is full of nebula

The original DBE put samples on blindly and not always correctly for a correct model

If you lower the min sample weight DBE will put more samples on the screen or you can apply them by hand ( some times best on a difficult subject)

You must remember to check the sample contents as they must be light to be included in the model and sometimes you will need to increase the tolerance setting

The new dbe tool makes better models and is more adjustable particularly important when you have faint nebula , which can be over flattened if you are not careful.

I must say that the default settings seem to work 90% of the time , but flexibility is important for the difficult jobs and on rare occasions DBE is applied twice the second time with a very low tolerance setting ( LEss than .1)

Clear as mud as they say:p

Hi

The star registration tool default is set for only a slight scale tollerance (0.1 under star matching) , this enables for speedier results.

So if there a scale differance you will need to alter this setting:icon_salut:

It also seems to crop the data from one edge.... think I 'll stick to registar for this as there are no settings to tweak it will just register anythign to anything....

Peter....

Ok

I can't win them all

But what do you mean it crops 1 edge:confused:

It works by registering to 1 image and any thing that fall of the edge of the referance is lost, is this what you mean

Mike, I have both programs, come over and spend an hour or two in my caravan, and you can see for yourself.

Pixinsight will do everything you are likely to need to do, without having to recourse to other software. Photoshop will do a percentage of it, but you will need other programs for stacking etc. However PI has nice little labels which tell you exactly what you are doing, in PS you will have to learn to do it manually.

I'm with Kevin, having both is ideal, the power of layers in Photoshop is something to be beheld!

As I say, best to see them in action, at Kelling. I would recommend watching Harry's videos on his site too.

[Tim]

Registar all the way Peter! If you had a mono camera you would love it even more!

Harry, I dont suppose you will be at Kelling heath this autumn?

If it isnt too far, pop along and say hello. I will ply you with tea, coffee or alcohol, and you can ply me with one on one tuition

The videos are great btw, very helpful.

[Tim]

If it makes it any more tempting, I have LOTS of M106 data just crying out to be processed properly!
