Hi all.
Anyone out who uses registar?
Is it worth the bucks or should i save for pix insight?
Suavi and Rick i know what you think. But feel free to reply! :lol:

Thanks

Scott

I use Pixinsight and I wouldn't use anything else

I own a copy of Registar and it is *very* good at image registration. Unfortunately, it doesn't do anything else ;)

Thanks Simon.


Thanks rick. Good to hear your praise for it. The good thing is i don't need it to do anything else!
I am trying very unsuccessfully to stitch together my carina mosaic with ps. Have a chat with suavi about the fits i have provided him with.

I think you can run Registar in evaluation mode, Scott. Might be worth having a play to see how it goes with your data?

It does its thing very nicely but you can't save the files.

I own a copy and love using it.
Here's one I did last year.

MilkyWay Rising with the Canon 1DX (http://www.iceinspace.com.au/forum/showthread.php?t=146173)

MilkyWay Region - Emu Rising (http://iimagespace.com/page/ds/emumilkyway.htm)

It's very good at what it does.

You can save the screen dump.
It does excellent job, in calibration mode the transitions between original frames are invisible.

Avandonk used it for his fantastic work.

Nice emu.
I think I am sold

Thanks bojan.
I will have a play when I get home.

Like you, I've tried many, many different photomerge type apps - Pt Gui, PS, Panogiga etc. to get my now 7 panel, 6 filter mosaic of Carina together.
Just need the damn clouds to disappear to finish it!
But Registar was the only one that just works.
Blindingly fast, accurate as all heck and well worth the bucks.
Bloody hard to find much if any documentation though, only a couple of tutorials on YouTube/ net.
Very surprised about that but wouldn't stop me recommending it. 😊

Just another plug for you-know-what, since it's expected, eh Scott? :D

PI supports some very powerful techniques for mosaics too. One that I've found useful with poor quality data (e.g. marginal overlap) is to generate a synthetic star field with CatalogStarGenerator and use it as a registration master. There's also the MosaicByCoordinates script which uses plate solve information to construct the mosaic. MBC can deal with the strong distortion of short FL lenses when constructing wide field mosaics.

As usual, PI has great tools... but you need to figure out how to use them ;)

Cheers,
Rick.

Thanks Andy for your thoughts.
It looks like the praise being heaped on registar and my brief experiments with it is convincing me to pull the trigger!

Thanks rick. I have to admit pi looks better and better each time it is talked about

Registar will beat anything!

That being said it does not work in 32/64 bit linear mode like PI.

What I have done for 'difficult' mosaics is to save the 16 bit registered images from Registar. Crop them as a new image and then use PI to 'align' these already aligned images with StarAlignment in PI and then use Gradient Merge Mosaic.

The inherent problem is that any image is a flat projection of a spherical image. Registar is far better at distorting to match images.
See post 11 here
It explains how to set parameters to make PI 'distort' more.

Registar is now 64 bit and there is almost no limit to image size or number of images. It is well worth the money.

Another way is to align your images with an image generated by Starrynightpro or similar with Registar and then the resultant mosaic image will have the least distortion due to the mapping of spherical to planar fields.
