On my PC, the above processes occur quickly with the 8MB binned 2x2 images I usually deal with. Save it (File>Save Image/Slice as FITS.) into your preferred folder. A stacked image is created and displayed. Select the appropriate responses in the dialog and click "OK". To stack the images, load them (File>Import>Image Sequence), then select Image>Stack>Z Project (yeah, I know that's not intuitive). The images will be aligned in a new subdirectory named "aligned" in the folder containing the original files. Make sure those stars are present in all images in the stack. Then place (by clicking) an aperture around each of a few stars. In the row of icons just above the displayed image (the first of the stack), find the one that is labelled "align stack using apertures" when you hover the cursor. Make sure you have enabled Virtual Stack in the dialog where you select the images. Load all your images using File>Import>Image Sequence from the AIJ toolbar.

Has anyone successfully built the software on a RHEL 7 or similar system? If so, what did you have to do to make it compile and link?Īlternatively, does anyone know of an easier (especially, more efficient) way to plate solve star field images? I have tried to use the native solver in ASTAP, but it has failed on every image I have of Delta Cephei, taken with a 250 mm lens and a 30 second exposure at ISO 200 and having a roughly 5.5 x 3.5 degree FOV. Adding the compiler flag -std=c99 gets me past that hurdle, but then the build fails at what appears to be linking build-hd-tree, with complaints about a large number of multiply defined functions. I have tried to build the software locally on a Linux machine (Scientific Linux 7.9), using the instructions for the very similar CentOS 7.8 on, following the link from, but this fails to compile catalogs/ucac5tofits.c out of the box. fits files and waiting several minutes for each one.
does a beautiful job, but this requires uploading large.

In addition to a larger catalogue of objects and a more accurate plate-solution, the advanced plate-solving available on AstroBin Ultimate also offers a Space Cursor to explore coordinates on your images, and full customization of the annotated objects, so you can turn on or off any of the categories above.After taking a number of science images, naturally now I want to plate solve them. GCVS (General Catalogue of Variable Stars) The following object categories are available as annotations: This means that wide fields will especially enjoy a more accurate plate solution.
With the advanced plate-solution provided by PixInsight, available in the AstroBin Ultimate subscription plan, images will be solved with a higher level of accuracy that accounts for field distortions (read more here). Some examples of what it looks like for AstroBin Lite and Premium The biggest limitation is that wide-field images are going to be less accurate due to field distortion (plate-solving works by star triangulation and wide fields will suffer from distorted angles).Īnnotations are only displayed, as they have since 2010, on the main image page, but not in high resolution.

The annotations identify most Messier, NGC, and IC objects, plus named stars. Users of the AstroBin Lite and Premium subscriptions get access to the regular plate-solving experience that has been on AstroBin since the beginning: it uses as a backend, and accurately solves most deep-sky images. Thanks to these tools, you can automatically identify and highlight deep-sky objects in your images, including nebulae, galaxies, stars, planets and a growing catalogue of asteroids.
AstroBin interfaces with and PixInsight to provide state-of-the-art plate-solution overlays and precise astrometry data.
