Guide for Combining Astronomical Photos Captured with Diverse Camera Configurations
Combining Multi-Focal Length Astrophotography Data with Astro Pixel Processor (APP)
Astrophotography enthusiasts often rephotograph the same celestial targets using different equipment to capture a broader range of details. One popular tool for processing and combining these diverse images is Astro Pixel Processor (APP). Here's a step-by-step guide on how to use APP to create stunning, seamless astrophotography composites from multi-focal length data.
Prepare Your Data
- Sort your images by equipment/setup (different focal lengths or cameras).
- Remove poor frames (with clouds, trails, or other defects).
- Take and organize calibration frames (darks, flats) for each dataset.
- Save each dataset into separate folders.
Set Up in APP
- Open APP and select a working directory containing your datasets. If the prompt doesn’t appear, use the ‘Directory’ button to navigate to your folders.
Calibration and Registering
- Load each dataset and apply dark and flat corrections.
- Use the registration step to align the stars properly for each dataset, even though they have different focal lengths. APP can handle different image scales.
Stacking and Blending Multi-focal Data
- APP can blend the datasets, combining details from wide-field and high-magnification images into one composite.
- The software matches the star fields and scales the images accordingly to provide a seamless blend.
- This process allows you to capitalize on the wider context from shorter focal length data and the fine details from longer focal length images.
Output and Further Processing
- After stacking and blending, APP produces a high-resolution master image.
- This output can then be further processed in other astro-imaging tools (e.g., PixInsight, Photoshop) for enhancement.
APP simplifies multi-focal-length stacking by allowing you to calibrate, register, and blend datasets from multiple imaging setups, producing seamless, high-resolution astrophotography composites.
To optimize your results, experiment with different settings in the 'Integrate' tab, save the stacked image in the working directory, and use the advanced normalization function on the '5) Normalize' tab. Additionally, go to '3) Analyse stars' to let APP review each light frame for star quality, and adjust the slider to 95%, set integrate to 'average', weights to 'quality', composition to 'full', LNC to 'no LNC', MBB to 5-15% (5% is generally fine), 'No under/over shoot', and then click 'integrate' on the '6) Integrate' tab.
Before opening APP, ensure you've removed any frames containing plane trails, clouds, or other unwanted elements from each dataset. Organize light and calibration files into separate folders for each dataset to speed up the stacking process. Dark and flat calibration images were taken for each dataset and saved into separate folders.
When opening APP, a window pops up asking for the working directory, the location where the data is saved. Repeat the process for light and calibration frames from dataset 2, selecting the 'session 2' option.
