Im not exactly new to astrophotography but I am definitely new to stacking images. I first tried deep sky stacker because it seems it's what everyone uses. Almost every time I've tried stacking it only wants to stack 1 image cause of a star detection error. I made the detection threshold so it would detect the most amount of stars and it doesn't help. I read other posts and thought it was a focusing error on the stars so I made sure to focus the image as much as possible and the error still pops up. The Orion nebula picture is one of a data set where I tried to stack and the error came up but the stars are very clearly visible. Any suggestions?
DeepSkyStacker 4.2.4 Beta 3 is now available.
Welcome to DeepSkyStacker 4.2.4 Beta 3
The main changes in this release are:
Fix to display Exposure, f-Stop, and ISO setting from EXIF tags in TIFF files. Update libtiff to 4.1.0 Automatic detection of CFA matrix based upon FITS keywords such as BAYERPAT, COLORTYP, and MOSAIC (for Meade DSI colour cameras). The FITS File tab of the Raw/FITS DDP Settings dialogue has changed. If you de-select the tick box for: "Monochrome 16 bit FITS Files are RAW files created by a DSLR or a color CCD camera", then automatic detection will be used. You can override this by selecting this option and manually selecting the CFA pattern to be used. All the other settings on that tab are now always available for modification. The exposure time is now correctly displayed for FITS files with the exposure time in microseconds (keyword EXPOINUS). Display a warning message saying that DeepSkyStacker won't de-Bayer 8-bit FITS images. Change code to read TIFF files in strips instead of by scanline. This can reduce the time to read the image by as much as a factor of 3. Refactor the code to decode the TIFF file we just read and also use OpenMP. Time to decode the image reduced by about 4-5 times. Refactor the code that writes TIFF files and use OpenMP to speed it up. Also write the output file in strips rather than scanlines. Substantial performance increase. Refactor the code that reads FITS files to make it easier to understand and also use OpenMP. Only a marginal performance benefit. Major bug fix - calibration frames were either not applied or incorrectly applied when using Super-Pixel mode. Clear skies
I just got an old kenko telescope cheap and I was thinking of going about modernizing it a bit. (okay its not very old)
Since the equatorial mount that came with the telescope said it supported attachment of a R.A. motor, I was thinking of putting one on but I couldn't find any information on what kind of equatorial mount this is, is it EQ1, EQ2 or EQ3?? (pictures below)
If it is EQ1 or EQ2, I was thinking of maybe attaching one of the simple type EQ 1/2 RA motors. (the economical types) Though I understand I need to ad hoc an adaptor to keep in place.
Also, I've read those are adjustable in the rotation speed... just how adjustable are they?
Any help would be great, Thx
Looking for a 12" DOB (or larger) which can be transported to Prestwick, Ayrshire. Any brand, as long as the telescope is optically sound and in good working order. I'm a reliable buyer who has bought and sold on this site before.
Please note that the translation of the help is not yet done. So the help will be either as it was previously or a mixture of (e.g.) French and English
The main changes in this release are:
The 32 bit version will now run on Windows XP SP3. It is likely that the next release of DeepSkyStacker will not do so. The stacking settings dialog width has been increased to reduce or eliminate the need to scroll the tabs. Add .rw2 to list of RAW file extensions. Change the colour scheme for DeepSkyStacker Live to make it more "night vision" friendly. Recognise and use GAIN values in FITS file from CMOS/CCD cameras in a manner similar to how ISO is handled for matching darks, lights etc.. Please note this is not the same as EGAIN (e-/ADU). It refers to the camera's scaling of EGAIN. Update help files and add a new Dutch version of the help. Issue #83: Provide the option to perform NO White Balance processing at all (requested by Ivo Jager for StarTools). Fix for issue #42 - the stacking method "Average" wasn't always reported in the recap html file. Common control library 6 now used so some cosmetic changes such as filled progress bars. Make the progress dialogs non-modal so that DeepSkyStacker can be minimised while processing. Update the DeepSkyStacker taskbar icon with a progress bar that matches the main progress bar. Saving of final TIFF file is now faster, and a number of other performance enhancements have been made. Ctrl-A will select all images in the file list (not the same as "Check All"). Del key will delete an image from the file list so you don't need right click and select "Remove from list" Bug fix - if you change the type of an image from the file list "Properties" dialogue, the icon was changed, but the text wasn't.
