So my recommendation is to learn how to take the best images for exoplanet photometry before worrying too much about whether one software package does better than another in the measurement step.
The "least amount of noise" gets into how you calibrate your images and what filters you use. Defocusing can be a problem in crowded fields, as neighboring stars start to contaminate your measuring aperture. The larger number of photons to get down to S/N=1000 or more usually requires defocusing so that the star image covers more pixels, none of which are saturated. The longer exposures are necessary to remove scintillation, a major contributor with amateur-sized telescopes. The main problems with exoplanet photometry are to get sufficient number of photons with as long exposure as possible, while introducing the least amount of noise. I recommend that you look at Bruce Gary's book to get oriented. Thanks.įor high precision work, the software used is less important than the observation methodology.

I would be interested in other's opinion of Mira Pro as well as any other software that might be better. Someone recommended Mira Pro, but that is the only recommendation I have received so far. fit photos? My objectives for this software are (in the order of importance):Ģ) As accurate as possible for extremely sensitive differential photometryģ) Versitile and capable of excellent analysisħ) Widely used by professionals and ameteurs Can anyone make a recommendation on what is the best software available for analyzing the. Second Question : I would like to do extremely accurate (as accurate as possible) differential photometry to study variable stars and especially exoplanets. Can anyone confirm that? Is there more accurate software out there that I should use instead of Maxim DL to take photos and report magnitudes with? I have a few questions:įirst Question : I heard that Maxim DL's magnitude readings are not very accurate. It also allows you to export your data to CSV or AAVSO format reports. It looks like all that Maxim DL does is plot the magnitudes of each star (target star, reference star, and check star) independently on a graph. I just ran my first photometry run with Maxim DL and a CCD camera a few nights ago. Hi, I am a complete beginner with photometry.
