Re: calibration (dark,Flat & Bias

Good day Fabio, I shall read through your comments and try them out. I have also had a friend give me some advice on creating darks etc and applying them and also how to create a master. No I meant to calibrate single images. I'm not an imager so don't usually do pretty pictures. I need individual i...

Re: calibration (dark,Flat & Bias

Fabio, I have now additionally done the flat field (inc the dark flats) correction and have a single corrected displayed. So i guess I now save this image. Which again I guess would be the 11 stacked corrected image. ? Suppose I wanted to calibrate the the II images individually. I suppose this coul...

Re: calibration (dark,Flat & Bias

Fabio,

I have successfully followed these instructions and have the single image with noise much reduced, but the flat faults showing. What would be the next steps?

Cheers, Eric

Re: calibration (dark,Flat & Bias

Fabio, Re point 1 i am finding in difficult to follow the instructions given in the manual and tutorial. I can load up the images, flats, darks etc into the pre-processing, but it's what to do next and how to proceed? your comments re point 2 seem to ring a bell with me so I shall look into this fur...

calibration (dark,Flat & Bias

I'm new to Astroart8. My familiarity with similar software is MaxIm Ver 6.14 and the sky X with which I've found calibration of images fairly simple. 1. Can I create master darks, flats etc that I could load and use for calibration instead of load say the 20 + images taken for each (akin to MaxIM) 2...

saving directly keyed instructions as short scripts

I have been reading through some of the messages on scripts and I recall reading that regular processes or commands keyed in could be saved as scripts and used. The impression I got that directly keying in manually processes could be directly saved rather than actually write a script. Am I correct i...

Re: Slew to star of given magnitude

Fabio, thanks for replying. The reason I asked was that on my present set up I use maxIm DL for focusing. I do not yet use AA& with it and I find it best to focus on a given magnitude star for a given filter. It would be useful for me there. On my new set up I will use AA7 from the start. many thank...

Slew to star of given magnitude

I have just set up a 2nd observatory housing a 16" Newt on Paramount ME and an Altair 10" RC on an EQ8 mount with CCD cameras Moravian and starlite express respectively. I plan to use Astroart7 to control and obtain images on both systems from the start for automated S?N searching and time series ph...
