TL;DR

This paper analyzes a large dataset of variable star observations, including supernovae and novae, to evaluate and improve photometric accuracy from naked eye to advanced standards, highlighting the balance between simplicity and precision.

Contribution

It provides a comprehensive analysis of over a thousand observations spanning 17 years, demonstrating how observational accuracy can be enhanced across different levels of instrumentation and expertise.

Findings

Improved photometric accuracy through data analysis.

Validation of naked eye observations against professional standards.

Insights into observational techniques from amateur to professional levels.

Abstract

The theory of General Relativity deals with very accurate measurements that show significant divergences from Newtonian predictions only with speeds near to the velocity of light. An introduction for educational purposes, based on naked eye photometry, deals with the radiation near collapsing star's shells like novae and supernovae. The theme of accuracy is drafted from entry level observations to the precision of professional data, often of public domain on the web. Thousand observations of variable stars, included the type 1a SN2014J, the Nova Del 2013 and the Nova Cen 2013, sent to the AAVSO by the author, with SGQ code, during the period 1998-2015 are analyzed to increase the photometric accuracy, in the occasion of the International Year of Light 2015.
