Re: After Preprocessing, How to Use Trichromy?

Hi, I suggest to start with L: do Preprocessing, (maybe save the settings if you want to repeat it later) then obtain the combined L image. This will show you which level of S/N you can expect in your final LRGB image. On the master L image, apply the filters you need (e.g. DDP, histogram stretch, n...

Re: Feature request

OK. This is not planned in the near future, so for the moment I can suggest the fastest procedure available: 1) For every night do a usual Preprocessing with the method Sum or Sigma+Sum. Maybe save the setting for later use. 2) Repeat for the other nights, leave all Preprocessing results opened in t...

Re: combining 1x1 lights with 2x2 colour

Hi, you can combine steps 1 and 2 with the single command "Coregister", which scales and aligns. If it's not possible to align automically, Coregister will ask you to select three stars (or three points) on both images. The procedure is: select the RGB image, click "Coregister", the select the L ima...

[-] (Numeric keypad). Zooms out the image. [Arrows]. Pans the image. [PAG_UP] , [PAG_DOWN]. Changes ...

Re: autoguiding query

Hi, about "reduced the pulsing", which option exactly ? By the way, I suggest to reset all autoguide settings (click the 3 buttons "Default values") and repeat the calibration (is it normal that RA is 2X faster than DEC?)

Re: Trying to quantify seeing/image-quality

Try the option "Confirm all images" with the option "Multithreading", prepare the left hand on the ESC key and the right hand on the RETURN key, usually it's possible to select/discard manually images quite quickly, I'd say that 300 images can be selected in 200 seconds. The options for automatic re...
