Making mosaic pictures

Postby cwardlaw » Sat Feb 11, 2017 11:51 am

I am beginning to create some simple pictures of The moon with my Alt/az mount at the moment. As my camera is not full frame I would like to/believe it is possible to create mosaics to join the various sections together?

Can anyone help me with how to do this please?

Thank you

It is possible. Any decent graphics program will enable you to overlay sections together. I often take a top and bottom of the moon and simply join them tother. As long as the photos have the same exposure etc, and one is taken within a minute or two of the other there is no problem. I did once put together a super sized photo with 8 exposures. (If I ever wanted it printing, it would take up half a wall!) Basically create a graphic big enough to accomodate all the sections. Cut and paste as sections, and join them together. I find it helps to keep the cut away from any edge where there might be different focussing or exposure from the rest of the image. I use Paint Shop Pro. Others use 'Photoshop', and there is 'Gimp' which is free.

Some graphic programs will have a 'stitching' process that smooths out any imperfections. I've never needed that for the moon.

It would be interesting to hear how others do this.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, with an 80mm refractor as a guidescope. They are housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC for imaging.

Microsoft's Image Composite Editor is a free Windows program that will analyse and stitch programs together in 2 dimensions. It's very straightforward to use - simply select all the images you want to try to stitch and ICE will work out how the parts fit together.
Scopes: Meade 8" SCT, Skywatcher 127mm Mak
For imaging: Pentax K5, Asda webcam, Star Adventurer (new toy)
For companionship: Mid Cheshire Astronomical Group.

I'd not heard of that before, so I thought I would try it out. I just loaded a north and south image of the moon, pressed the button and voila - a whole picture of the moon! 'Wonders will never cease' !
It doesn't do it any better, but it is a lot easier and faster.
I wonder if it will work for other objects?

Many thanks for the suggestion. :ugeek:

Yes, I use Microsoft ICE extensively. I also use it for stacking full disc lunar images.
