... camera itself, or on the filter wheel. For most setups, rotation will rotate both, so the dust motes will not change due to rotation. What may - or may...
Hi, I have a SXV-M7 camera mounted on a manual filter wheel inserted by an extension tube on the Crayford of a 80 mm. APO refractor. I am now trying to...
Hi Paul: No, the guidescope does not have to be precisely aligned at all---in fact one advantage of a separate guidescope is the fact that it can moved a ...
Last night was "first light" with my Pentax 125 SDP and it's dedicated reducer...image capture with Proline 16803 and FLI HA filter these were taken about 12...
Good start, Alex. You've got some good data there. My only suggestion would be to look at the dark end of the histogram in your image...it might be "clipped"....
Hello All! To get an image of Vesta through a C14 and an SBIG ST8 camera that is using a Celestron 0.63 focal reducer, how much total time do I need to expose...
The mount is what is aligned to the pole. There is a single axis (north to south pole). That is what the guide scope is helping you follow. Any star on the...
Paul If you are imaging the same subject for any length of time you will introduce field rotation; obviously the more off axis the guider the more rotation....
All, As I understand there will not be an issue if you are polar aligned accurately (to the mean refracted pole). With any residual error the field will...
... Because you are guiding. Keith PMMail/2 Tag->Keith Myers.... computing into the future with eComStation! This OS/2 system uptime is 0 days 17:42 hours...
Thank you all for kind comments, so I am going to work on my "blacks" and look at histograms, the question I have is how to be able to pull more details of...
I think I can answer this without being inaccurate. The reason this is possible is that both guidescope and mount, although pointed at slightly different...
Hello all, This couple is M97 and M108 together. Object : M97 and M108 Common name : Nébuleuse du Hibou et Galaxie M108 Date :16 mars 2007 Optics : Lunette...
If I stacked 70 images on one night and then 30 images taken from the other night, and then combined two resulting pictures (first stack of 70, second stack of...
short answer: Yes. Longer answer: there could be differences in the data for the two nights that might affect results. For example, the FWHM might be larger...
... This is my understanding also, but within particular limits, due to atmospheric refraction. That's why the guidescope "offset" is usually kept to as...
Hi, Have they improved or solved any of the problems that people seemed to have with the YR Nugget guider? I was just curious as I have not seem much in the...
I have Hap Griffin Astro-Cable for canon 350D, any idea where can I get an adapter to use with 20D ?? anyone can sell one ? I am not too friendly with the ...
... You can use N3 based remote switches that have 2.5mm syncro sockets for this purpose. Further details here (scroll down to the picture of the ADIDT M1 C3):...
Steve, ... If you take a set of exposures an hour apart, you should see movement between the two sets. Vesta is bright, magnitude 6.1 (according to The Sky),...
Thanks Andy. I am using the ST10 internal guider. I had to move the object a little bit to find a good guiding star. My guiding exposure was 8 seconds. ...
