Hi, When you for the first time setup an off-axis adapter it can be confusing, at least it was for me. I have written down a tutorial that maybe can be of some help: http://www.astrofriend.eu/astronomy/tutorials/tutorial-setup-off-axis-adapter/01-tutorial-setup-off-axis-adapter.html I will edit and do some complement in the text later. A question to all you that already have an off-axis adapter, what make and model do you have ? Are you satisfaid with it ? /Lars
A lot of people have asked me about the iso setting and what is going on inside the DSLR camera. I have tried to do a simple tutorial about this on my homepage: http://astrofriend.eu/astronomy/tutorials/tutorial-iso-dslr/tutorial-iso-dslr.html Now when DSLR cameras get better and better it's not that big advantages to use high iso setting. On earlier high noise readout cameras you could raise the signal above the readoutnoise by using a high iso setting (but depends on the camera if the amplifier was good enough), but in the same time you lower the dynamic range. With a better new camera you can lower the iso setting and stretch the data in your imageprocessing software and still have the same (or almost) low signal details. And with that get a higher dynamic range (don't saturate or clip the high levels). With my new Canon 6D I normally use iso800 but also iso 400. Modern Nikon cameras with Sony sensors are even better. Normally you can read about isoless cameras, that's the ones that can take advantage of lover iso setting. Depends on the object what to prefer. One important thing to know, the iso setting doesn't change how many photos the camera detect, just how the camera read out the sensor. Hope I clearify and not confuse with my tutorial. /Lars
Hello, I’m strongly interested in getting Mel’s (Astro Baby’s) tutorial for disassembling/fixing/reassembling the SkyWatcher AZ-EQ6 mount from Synta. I know it should be somewhere in East Midlands Stargazers website, but it seems to be unreachable. Maybe she also posted something like that in Stargazers Lounge. Could someone give me please some help to find it out or to contact Mel in order to ask her for it directly? I'm also looking for contacts with Scott Cunnington, author of a tutorial on the same topic I succeded in finding, with whom I would like to discuss some details of the proecedure. Thank you very much. Greetings, cesco
I've been asked on a number of occasions, how I managed to do planet astrophotography with a manual Dobsonian telescope. So I have created a tutorial, to help fellow owners create a worthy image. I hope it makes sense and you find it useful. Dob AP Tutorial.pdf
