Digitizing the Cosmos - An Introduction to Astroimaging
I'm an amateur astronomer and imaging scientist living in Concord, MA.
I’ve been imaging since about 2011, and so far, it's been a *lot* of fun.
It's also been amazingly easy to do, despite the seeming complexity of the process.
As with most things in this wonderful life, the first step is the hardest, and
so it is with this. But, once you get started, I promise you, the fun never stops!
I am by no means an expert, but the beauty
of this is you don't have to be, and remember, *everyone* starts out as an amateur.
I've finally made my presentation available describing how to get started in
both deep sky imaging and planetary video imaging. I've also put together a document
describing how to begin processing in DeepSkyStacker, complete with screenshots from
the program. Hope this helps! Just click on the icons below (note: you need to enable

Below are a number of links to resources that I have found useful.
- DeepSkyStacker: a wonderful freeware
program for astrophotographers, by Luc Coiffier, that simplifies all the pre-processing steps for stacking deep sky images.
There are many commercial alternatives, but I've had a great deal of success and fun using this program to create
wonderful records of some fantastic objects in the Universe. You can see some of the
- RegiStax: free software by Cor Berrevoets et al. for
alignment/stacking/processing of planetary images. Try not to be intimidated by this program. It's complicated, but its default
settings are superb.
- Castrator: a very useful tool by Emil Kraaikamp
for reducing the size of planetary videos to drastically speed up processing in RegiStax
- STOIK Video Converter: this website
has a link to a trial version of software that does WMV to AVI conversion. I'm sure there are other
programs, but this seems to be virus / ad free and has the minimal functionality I need. And, of course,
if you like it, you can always purchase the entire product!
- GIMP: a great general FREE image processing program that does almost everything
that Photoshop does! I can do all my postprocessing with this program!
- UFRaw: a FREE plugin for GIMP (or works standalone too) that can handle
processing of 16 bit images. I've played with it myself, but don't use it in general. However if you want to overcome
the 8 bit limitation of GIMP, you might find this useful. I find that if I do my processing in DeepSkyStacker well
enough, the 8 bits in GIMP is good enough. Freeware and it's safe, but your call!
- Go to this site, if you need *any* type of adapter for your camera and
telescope. It's run by CNC Parts Supply Inc. and they are always willing to respond to emailed questions about any of their
- Another site that has a huge supply of telescope related items that you might not find elsewhere
is Scope Stuff
- Go to iTelescope.net to get a FREE trial membership on a robotic on-line telescope. They
give you approximately 30 minutes on a single color shot telescope in New Mexico that you can use on a first come first
serve basis! Great fun if you want to get a glimmer of what it's like to start imaging yourself!
- If you're interested in converting a Logitech 9000 camera to a web cam for planetary photography,
this site by Gary Homis gives a great detailed play-by-play description,
which may even be useful for adapting other web cams as well! Definitely worth a look...I took all my early planetary images with
a converted Logitech 9000 and was able to get some *really* nice results. Since 2015, I've been using a
Celestron Skyris 132C color camera that has a faster frame rate
allowing more frames for processing and producing even better results! Check out these
comparison images between the converted Logitech
images and the Skyris.
- And remember...the internet is your friend! There are a lot of people out there that are very knowledgeable and
more than willing to help. Try out these three yahoo newsgroups: DeepSkyStacker, RegiStax and ISSTracking. There are of
course, many others, but these are specifically applicable to the programs I list above.
For those who might be interested in attending sessions of the Skylight Astronomical Society, Inc. we have
our regular meetings on the last Thursday of every month at Rockbottom Observatory in Stow, MA. Several maps with directions appear below. Please also visit the
