...The HST/WFC3 IR Point Spread Function: A 13-Year Empirical Characterization for Precision Astronomy in the JWST Era Telescope’s Wide Field Camera 3 infrared channel (WFC3/IR) point spread function, analyzing 512 high-quality PSF measurements from 13 years of archival observations (2010–2023). Using a statistically robust sample across multiple filters with precise focus values (–2.0 to +2.0 µm), we quantify: (1) focus-dependent FWHM variations of 18.7% across the operational range, following a parabolic relationship with minimum at focus =–0.2 µm (FWHM(focus) = 1.92 + 0.031·foc

Telescope drive using a ATMega2650 and RAMPS 1.4 Board. The interface uses standard LX200 instructions. Different timers are used for RA and Dec Axis to achieve higher and more precise stepper frequencies.

PARot is a program for ultra fast and precise polar alignment of equatorial mounts. You can easily achieve alignment accuracy better than 1 arcmin in 5 minutes of time. You take one image of the celestial pole, rotate the mount around the RA axis and take another image. The program compares the images and shows you the necessary adjustment. The adjustment process is controlled by the live-liew created by your camera.

Mobile Planet Tracking, lets you track the position of any of the 8 planets in the Solar System, you can specify your current earth position, date and time to get the most approximated values.

AtomicGPSClock is a low cost alternative to keep precise time on your computer. It utilizes any GPS that outputs the NMEA 2.0 protocol via RS-232 to accurately set a computers clock. For standalone, mobile, or network (SNTP) installations.
