AstroImager



AstroImager - AstroImager is a powerful, but easy to use image capture application for the astrophotography. (OSX) AstroTelescope - AstroTelescope, is a simple planetarium and telescope control application for the astrophotography. One of the best ways to learn what works best in astrophotography is to experiment. I’ll be detailing my experiments which should help you to answer the questions you have in your own journey. Perhaps it will save you time and stress and speed up your own progress. Need ideas or want to collaborate?

Keith's Image Stacker is an image processing program that is oriented primarily toward astrophotography. See my astrophotography webpage for information about my personal venture into that hobby. What Keith's Image Stacker provides, more than anything else, is a workspace in which to align many similar images (say from a quicktime movie of Jupiter taken through a telescope with a webcam) and then to produce a stack of the images, which consists of a single image that comprises either the sum, or the average, or some value in between of the individually stacked images. Stacking images is a well-established method for increasing the signal-to-noise ratio in a series of similar images. True 'information' will shine through the stack, while random noise will drop out.

Here's are some examples of what can be accomplished with this program:

One frame (above, left), stack of 61 such frames with various processing (above, right)

Keith's Image Stacker is 'uncrippled' shareware. For the endless hours of work I have put into creating this utility I ask that you please pay me $15.00, which automatically registers you for all future versions. In return I will place you on an extremely infrequent mailing list to be directly notified of version updates when they occur. Specific instructions for paying can be found in the README file that is bundled with the program. Thank you.

Thank you, and please contact me and tell me what you think of this program. I would really like to know people's reaction to it.

I have attached a composite I did with my R2 imager in Feb. at the Winter Star Party in Chiefland Florida this year. This was with no post processing. Images were captured through my 8' Meade LX90 in Alt Az and captured with Sharpcap. My R2 attached to my 8' gave me better views than the 20' dob that was beside me was seeing. He could not see the Horsehead with a $150 filter, I got a wonderful view without a filter. It was a cold evening with lots of dew but I was sitting in my heated tent warm and dry, controlling my scope with Sky Safari on my iPad and seeing more on my computer screen than my fellow observers and in color no less! I love the detail I am able to see.

Astroimager Tutorial

'The RI may be the most exciting $300 astronomy purchase I've ever made. I could barely sleep last night after viewing M51, M81, M82 and Jupiter on my first evening with the new gear. I've been in the hobby since 1960 and last night was the first time I experienced the same awe as I did the first time I 'discovered' Saturn.
Thanks for making such a wonderful and affordable product.'

Thanks a lot. I'm really looking forward to using it for our astronomy outreach.......and just to show you that you CAN teach old dogs new tricks...I'm a 72 year old Lady! I really love the new technologies that are coming out now. I've been waiting for something like this very item and, when one of the other people in our club showed up at our last star party with this, I just HAD to have it!!

“ I do believe that the Revolution package will shake-up and wake up new interest in amateur astronomy. One does not have to pack up and drive a distance to get remarkable results. Neighbors' lights are no longer a problem (other than for the ecology).
My neighbor was astounded by some images I showed him on the spot, and was as surprised at the low cost (value) of the video components.
This has definitely rekindled the fire of discovery I felt in prior years, as I hope it will for many others. “
