Ta diplomska naloga raziskuje astrofotografijo s poudarkom na tehnikah in opremi, ki so ključni za zajemanje globoko vesoljskih objektov (DSO), kot so galaksije, meglice in zvezdne kopice. Z napredkom tehnologije je astrofotografija postala dostopnejša tako amaterskim kot tudi profesionalnim fotografom. Raziskava preučuje vpliv svetlobnega onesnaženja na kakovost slik, pri čemer se uporablja Bortleova lestvica za določanje primernih lokacij. Ključna tehnika »stacking« je bila skupaj z uporabo kalibracijskih slik uporabljena za izboljšanje ostrine slike in zmanjšanje šuma. Eksperimentalni del raziskave je vključeval testiranje osnovne fotografske opreme, da bi ocenili njeno učinkovitost pri astrofotografiji. Raziskava je potrdila pomembnost natančne postavitve opreme, še posebej uporabe sledilca Sky Watcher Star Adventurer GTi za natančno sledenje nebu. Rezultati kažejo, da natančna kalibracija in obdelava slik bistveno izboljšata kakovost posnetkov. Zaključek raziskave je, da uspešna astrofotografija zahteva ne le tehnično znanje, temveč tudi sistematičen pristop pri ravnanju z opremo in obdelavi slik. V prihodnjih raziskavah bi bilo smiselno raziskati še drugo opremo in naprednejše tehnike obdelave slik.

Abstract

This diploma thesis researches astrophotography, focusing on techniques and equipment es-sential for capturing deep space objects (DSOs) like galaxies, nebulae, and star clusters. With advancements in technology, astrophotography has become more accessible to both ama-teurs and professionals. The research examines the impact of light pollution on image quality, utilizing the Bortle scale to identify suitable locations. A key technique, “stacking”, is applied to enhance image clarity and reduce noise along with the use of calibration frames. The experimental part of the study involved testing basic photography equipment to deter-mine its effectiveness for astrophotography. The research confirmed the importance of pre-cise equipment setup, particularly the use of the Sky Watcher Star Adventurer GTi for accu-rate tracking. Results show that careful calibration and post-processing significantly improve image quality. The study concludes that successful astrophotography requires not only technical knowledge but also a systematic approach to equipment handling and image processing. Future research could explore other equipment and advanced image editing techniques.
