I have been playing around with building a barn-door tracker for some months. Spent some time this-aft doing some trigonometry and spreadsheeting, and I now...
Way to go Colin! I too did a similar thing a couple of decades ago. Something that I was not aware of: The King rate, very slightly different from the sidereal...
Hello Astrophotgraphy group, I am looking to purchase a photo of the night sky taken in/near/around Edmonton. A friend of mine is a astrophysics student who is...
This isn't a particularly busy group at the moment, and we don't have a lot of rules, but there are some 'stellar' photographers that follow this list, and...
Hi Leah, You can check out some of my work here on Flickr. I have a few "iconic" shots of Edmonton and Auroura, including one that made the Astronomy Picture ...
Hi Colin, As to what I'm looking for, I'm not a huge astronomy buff myself, so I don't really have anything in particular in mind. I was mostly hoping to get a...
Leah, Your request is like blood in shark infested waters... I don't think I have anything that would be quite right, but I wonder if Alister Ling or Luca...
Luca has an APOD shot of the moon over downtown, as well Greg Scratchley has an NLC photo (also APOD) with downtown Edmonton in it I think too. All would be...
Mass, How do you take Bias frames? http://www.starlightccd.com/faq/platt/platt5.htm Lance ... -- "All things are possible with enough Time, Code, Money, XAND /...
If I remember correctly, with a lenscap on, you take the shortest possible exposure at the iso you are going to use. --Colin ... Colin Peart Sent from mobile ...
I thought those were dark frames? Oh yeah.. I just purchased Nebulosity 2. This software is amazing! http://www.stark-labs.com/downloads.html I am off next...
A dark frame has the same exposure time as your light frames. A bias frame has the shortest possible exposure time your camera can do -- it's the noise ...
Thanks Colin, that clears that up for me. =) ... -- "All things are possible with enough Time, Code, Money, XAND / XOR Beer." Twitter:* *@lancetay E-Mail*:*...
Keep in mind that you don't need bias frames if you take darks at the same ISO. Since bias signal is present in every frame you take, darks will have bias...
I am tempted to go out to Blackfoot this weekend, when were you planning? Trying to work out all the bugs in my setup before next new moon. Updated my...
Massimo, I just downloaded 2.4.5 beta of Neb2 and it appears to now include DIGIC 4 support for 550D/600D. http://www.stark-labs.com/depot/beta/ I will test...
Anyone play around with this package before? Just tried out the image stacking options in it, and it doesn't do to bad of a job either. But, holy kaw.. what a...
Just stumbled across this 'Astronomy/Imager' forum today: http://www.astronomyforum.net/astrophotography-image-processing-forum/105994-new-dslr-tutorial.html ...
Yes I used Iris particularly its spectro functions. A bit unusual, but extremely versatile and powerful. Once you get over the initial learning curve it's...
Looking at the weather forecast it looks like Sat is better and Sun is best. Now that the Sun goes down early enough it is possible to go out even if the...
Will keep an eye here, and on the sky. Sun is out for me.. work on Monday, so perhaps Saturday night. ... -- "All things are possible with enough Time, Code,...
You wuss! :-) Darryl and I were out at Blackfoot on weekdays around Summer solstice. Following day at the office was dedicated to clean up old files, read a...
Yes, the version below in beta repository supports my camera now. Bonus, and I can run it on the PC an MAC. =) ... -- "All things are possible with enough...
Ok weather is supposed to be nice tonight. Darryl and I will be out at Blackfoot. Moon is still in the sky, but I will be imaging either Abell 72 or NGC6934 in...
