The "All Seeing Eye knows all".... Actually Stuart, I downloaded your image, then viewed it in Canon's Digital Photo Professional application. There is a lot...
A very good start, Stuart! - Jerry Hudson Stuart Forman wrote: At our last imaging meeting I mentioned I would post my attempt at the Orion Nebula This is an...
Good job Stuart. By all means try ISO 800, (as for an unguided shot you will be able to use a shorter exposure) but you may find that sky glow (for a longer...
Skies cleared up tonight. I'm going to try the 45 second exposure. But if I want to take multiple images and stack in images plus how long should the exposured...
Your sky must be different to mine! The individual exposure length should be as long as you can go without (1) the stars trailing or becoming ovoid, and (2)...
Thanks Chris, It clouded up soon after I wrote that email. Does anybody know if Images Plus (or Elements) has tools for decreasing light glow? I just as soon...
Hi Stuart, I enjoyed your Orion Nebula saga and had some thoughts. I think the idea of shorter exposures (unguideded) are the way to go. Judging from your...
Hi All; especially I think Bob. Does anyone own one of the newer Nikon DSLRs? By "newer" I mean younger than the D-100 and with the larger chip. If you do...
The gemini user group has been discussing a device call "telescope drive master" One user reports: "My results have shown a consistent Periodic Error of +/-...
Hi Jim, Yes, I do have a nikon d300 and I use it with older nikon lenses. The D300 has an aps sized sensor so a 1.6x factor applies for the lenses (sensor is...
45 second exposure with ISO 800 with sharpness slightly modified in Canon software. The new one is "800 45 resized". I included the old one for comparison...
Ron Taking you literally here. Should I go out and take 50 exposures at ISO 800? Or should I use a lower ISO. I took about 15 exposures at ISO 200 for 20...
Last night I took about 40 pictures of the Double Cluster. The object was relatively low in the sky so skyglow was a problem. I would have taken more, but a...
Hi Bob, Don't bring the Nikon on my account. I might not make the meeting. Your thoughts are fine for me. My D-100 actually works quite well. It soulds...
Hi Stuart, You could probably download Registax free. I think you could stack your images with it. It offers several stacking options, image processing...
Great idea, Jim, thanks! Okay, I downloaded it. Not intuitively obvious on how to use it, though. I'll play with it and see if I can figure it out. If I can...
Hi Jim, For show and tell, I will be bringing some of the MDOA hardware recently purchased - projection adapter, off axis guider, and guider from Orion... Here...
