Procedure for Finding Limiting Magnitude477 views1. Set up and polar align Tak. NJP mount with 8" Newt. with SBIG 11000
2. Locate NGC 2403
4. Locate guide star and calibrate guider
5. Take sequence of 5, 10, 30, 60, 120, and 600 sec.
6. Open dark-subtracted images in MaxIm
7. Using the settings above, find magnitude and SNR of the three circled stars
8. Record Magnitude and SNR of each in Excel
9. insert the formula "=(LOG(SNR Star x/3)/LOG(2.51))+Magnitude Star x for each star to find the limiting magnitude using a SNR of 3 as the limiting magnitude
