Quote:I did a little searching and found a blurb in the FAQ's at Stark Labs about Nikon support for the software. It takes a lot more code. So, the Canon interface is easier to write code for. Not that the cameras are one better than the other, the aftermarket support is higher on Canon, because folks can handle writing code easier for it.

Quote:Does the PEC work in conjunction with a guide star? I'm not familiar yet with how that works.
Quote:On the interesting Nikon lenses I have... I have the AFS 300mm f/4D ED-IF. I shot the full Moon with it last year but I normally use it for birding. That shot of the Moon was with just the 300mm but I also have the Nikon TC14E, 1.4x teleconverter that works really well with the 300mm for birding.
Quote:I also have the famous AFS 85mm f/1.4G lens, for portrait work... but because it is so fast and razor sharp, I could see how it would be interesting.
Quote:For WA, I have their equally famous, AFS 14-24mm f/2.8G, which is an amazing lens!
Quote:So, please tell me, do you just piggyback the DSLR to the scope on the mount with one of these lens and have at it?
Quote:Your Nikons will do but Canon will be better; once you get into serious imaging, you'll need to mod your camera for AP, but for now try what you have.
Quote:Thanks for the explanation of PEC! Sounds tedious and I see why folks pay for an autoguide system and be done with it.
Quote:My 100mm Apo has rings that are drilled and tapped for 1/4-20 on the top. My 300mm lens has a lens collar and I have a Feisol QR plate on it. I'll just buy another Feisol dovetail and screw it into one of the ring 1/4-20 holes.... done!
Quote:I looked at your shots and they are quite good! Are they cropped a lot?? I don't have a sense yet of the size of things and what we have to work with.
Quote:The 14-24mm is used fairly often for milky way WA shots. In the Nikon Capture software, you can select to flatten its field curvature. Or... you can leave it alone for that effect also.
Quote:For prime focus, I have the CNC Supply True 2 Nikon adapter showing up any day now. I hope I can get the scope to balance with the camera mounted. Otherwise I'll need a longer dovetail.
Quote:I'll play around and see what happens!
Quote:It is useful to look at the sizes of objects in a planetarium program. Some of them even let you input your camera sensor size and lens and/or telescope focal lengths to show you a preview of how things can be framed up. I use Stelarium for that - it is not the most full featured program for this, but it is quite good for a free app.
