Hi Ivo, No problem & merry Christmas and New year :-) I did another stack without flats and it looks horrible, I redid then another stack with an other set of flats taken with the T-shirt method, and It looks a little bit better, but not much. I also triyed a stack with DSS set to auto-WB and it was...

Good day, This is the second set images taken with my modded 1100D that I try to post process in StarTools, and the troubles are not jet over.... in the first set I had problems with flats, I could solve those a bit, with the help of Ivo and Rowland. this is the link to that tread: http://www.starto...

Good day, A little update, I have modified my self made Led Light box by adding on the back of the light box reflecting side a blue plastic film coming from a plastic office maps, you know, the one's to put A4 documents inside? The one on right most side is the histogram of the resulting Flat, all t...

...... Other things that might affect your results - temperature consistency across the whole data set. It is not unusual for the lines to be absent in an uncalibrated stack. This doesn't mean you should not calibrate, the lines may be present because the calibration frames, most likely the darks a...

Hi Ivo & Rowland, Ivo, I agree, I do not discern the streaks in the light only stack, I am also completely at loss about what is going on. Rowland, unfortunately DSS will not let me do what you propose as stacking method... :( The data in the second link was a set without Flats... I use DSS nearly o...

Good day Ivo, I have checked the PHD logs again, and it looks the dithering was done. correctly after each frame: here two sample extracts: INFO: SET LOCK POSITION, new lock pos = 635.725, 475.230 INFO: DITHER by 0.088, 0.191, new lock pos = 635.829, 475.413 ##### INFO: SET LOCK POSITION, new lock p...

Hi Ivo, Thanks for your response. The CR2 attached in the previous post does not have flats subtracted, Rowland just asked for a single stretched image. The set of CR2 were taken with APT and guided with PHD2, and the dithering was done without any errors reported from APT. I have uploaded in Google...

Hi Rowland, Thanks for your mail. The light frames were just CR2 files stacked in DSS, and the resulting autosave file opened in ST no preprocessing done. The EOS was attached to a Meade LS6" SCT FR 6.3 I don't know where the truncating/clipping could have happened. Could the full moon have somethin...

Good day Ivo, Please check this image, it is the first image that I have taken with my freshly self modded EOS1100D (yesterday night with the full moon. On the center/right side of the image there are a sort of diagonal streaks, I don't know if they are caused by moon, or by a to much stretched imag...

Hi Caley, StarTools can appear to be a bit complicate at the beginning, but it is actually easy to use once you get used to its way. Here a log of a typical session, from uploading the "Virgin" DSS file to saving the results. Try and apply them to your file. -----------------------------------------...
