Coronado SolarMax II 60 NexImage Registax Panoramic

Creating a full-disk solar panorama is not always straightforward when using a dedicated solar telescope and a CCD camera. With the Coronado SolarMax II 60 and NexImage CCD, the apparent solar disk can be too large to fit into a single frame at native resolution.

Instead of reducing magnification or sacrificing detail, I decided to apply a classical astrophotography solution: build a panoramic mosaic of the Sun.

The idea is simple in principle but requires careful planning in practice:

• Record multiple overlapping solar segments (in this case – three videos).
• Keep identical exposure, gain, and duration settings for each capture.
• Process all videos using the same stacking parameters in RegiStax.
• Export uniformly sharpened frames.
• Merge them using Photoshop → File → Automate → Photomerge.

Consistency is critical. If video duration, histogram levels, or wavelet sharpening differ between segments, the final mosaic will show visible seams. Proper overlap between frames is also essential to allow accurate alignment of solar features such as filaments and prominences.

This workflow is very similar to techniques used in:

• Nightscape panoramas (for example, multi-frame Milky Way images)
• Large-field “Rainbow Milky Way” mosaics
• Deep-sky mosaics when a single frame cannot capture the entire object

Solar mosaics require the same discipline — but with an additional challenge: the Sun evolves quickly. Prominences and surface detail can subtly change during capture, so recording segments efficiently is important.

The final result below demonstrates how three stacked segments were combined into a seamless panoramic solar image.

This example shows that even with a compact solar setup, it is possible to produce high-resolution full-disk results by applying classical astrophotography mosaic techniques.

RegiStax 6 - Astrophotography Saturn - Testing new version v6

In April 2011, RegiStax 6 was officially released — and I immediately downloaded it to test on one of my favorite planetary targets: Saturn.

For planetary astrophotographers, RegiStax has long been one of the most important free tools available. The new version introduced major improvements in alignment, wavelet sharpening, and processing speed — making experimentation much easier and more intuitive.

What Was New in RegiStax 6?

Release date: April 2, 2011
Platform tested: Windows Vista

Installation was simple and smooth. Compared to Version 5, the interface became noticeably more intuitive and streamlined.

One of the biggest improvements for me was the multi-alignment feature. In Version 5, I occasionally experienced alignment issues. In RegiStax 6, alignment worked flawlessly — almost like magic.

The introduction of Linked Wavelet Layers was a game-changer. This allowed more controlled sharpening adjustments across layers, producing smoother yet detailed planetary surfaces.

Processing speed was significantly improved, allowing more experimentation with parameters — essential when trying to extract fine details from stacked planetary frames.

Equipment Used for Saturn Imaging

Telescope: Celestron NexStar 4SE
Barlow Lens: 2× Barlow
Camera: NexImage planetary webcam
Location: Brooklyn, New York
Target: Saturn

This setup represents classic early-2010s webcam planetary astrophotography — recording AVI video files and stacking thousands of frames in RegiStax.

Processing Workflow in RegiStax 6

The video above demonstrates the full workflow:

• Loading AVI video file
• Setting alignment points
• Frame quality analysis
• Stacking selected frames
• Wavelet sharpening (linked layers)
• Final image optimization

Stacking video frames dramatically improves signal-to-noise ratio and reveals planetary details such as Saturn’s ring structure and atmospheric banding.

Why RegiStax Was (and Still Is) Important

In the early 2010s, RegiStax was one of the most accessible tools for amateur planetary imaging. It allowed backyard astronomers — even from urban environments like Brooklyn — to capture detailed images of planets.

Even today, many astrophotographers use RegiStax for final wavelet sharpening after stacking in AutoStakkert.

Huge thanks to the developers of RegiStax for creating and maintaining such an incredible free tool for the astronomy community.

Saturn Celestron NexStar 4SE Telescope RegiStax NexImage

This post documents my backyard astrophotography session capturing Saturn near opposition (March 20–25, 2011) using the Celestron NexStar 4SE telescope and Celestron NexImage CCD webcam.

The video below shows the complete workflow — from GoTo alignment and telescope setup to live planetary capture and final image processing in RegiStax.

Backyard Planetary Imaging Workflow

Location: Brooklyn, New York
Telescope: Celestron NexStar 4SE (GoTo, Solar System Align)
Camera: Celestron NexImage CCD (VGA 640×480)
Barlow: 2× Barlow (1.25")
Capture Software: AMCap
Processing: RegiStax 5.1.9.2

The video demonstrates:

• Solar System GoTo alignment
• Selecting Saturn in the NexStar controller
• Physical setup of telescope and NexImage webcam
• Live capture of Saturn using AMCap
• Stacking and sharpening workflow in RegiStax
• Final processed Saturn images

Capture Details

Two video sequences were recorded:

• 7 minutes (420 sec) at 5 fps → 2100 frames
• 1 min 40 sec (100 sec) at 10 fps → 1000 frames

Processing settings in RegiStax v5 included:

• Align: Default / Center of Gravity / Gradient2
• Drizzle optimization
• Wavelets: Gaussian (Initial Layer 2)
• RGB Align – Estimate
• Histogram stretch

Even from an urban backyard, careful stacking revealed remarkable detail in Saturn’s ring system.

Cassini Division from a Backyard Telescope

A thin black gap in Saturn’s rings — the Cassini Division — is clearly visible in the final stacked images.

The Cassini Division is a 4,800 km wide separation between Saturn’s A and B rings. Observing it with a 4-inch telescope under city skies is always a rewarding confirmation of good seeing conditions and proper processing.

Small Telescope, Real Planetary Detail

This setup demonstrates that meaningful planetary astrophotography does not require a large observatory or expensive professional equipment. Even with a small and relatively affordable 4-inch telescope like the Celestron NexStar 4SE, a basic planetary webcam, and proper stacking techniques, detailed views of Saturn are achievable.

Features such as the Cassini Division, ring shadowing on the planet’s disk, and subtle atmospheric banding become visible after stacking thousands of video frames and applying careful wavelet sharpening.

This is one of the most exciting aspects of modern amateur astronomy: high-resolution planetary imaging is accessible to backyard observers using compact, beginner-friendly equipment.

Jupiter 2010 Opposition - Celestron 4SE NexImage Registax

These images and video capture Jupiter during its 2010 opposition, photographed on September 20 and September 21, 2010 from my backyard in Brooklyn, New York. Planetary opposition is one of the best times to observe Jupiter, as the planet is closest to Earth, appears brighter, and shows its largest apparent disk.

All video data was recorded using a Celestron NexStar 4SE telescope with a 2× Barlow lens and the original Celestron NexImage CCD camera. Despite heavy urban light pollution, Jupiter’s cloud bands and the Great Red Spot were clearly resolved using high-frame-rate video capture and stacking techniques.

Capture & Processing Details

• Telescope: Celestron NexStar 4SE
• Camera: Celestron NexImage CCD
• Barlow Lens: 2×
• Frame Rate: 10 frames per second
• Exposure: 1/10 second
• Video Length: ~4 minutes per capture
• Total Frames: ~2400
• Resolution: 640 × 480 (AVI)
• Stacking Software: RegiStax v5
• Final Processing: Adobe Photoshop

The AVI video files were stacked in RegiStax v5, where the best frames were aligned and combined to reduce atmospheric turbulence. Wavelet sharpening was applied to enhance fine details, followed by final contrast and color adjustments in Photoshop.

The video demonstrates the complete planetary imaging workflow: the physical backyard telescope setup, live Jupiter capture using AmCap, raw CCD footage, RegiStax stacking and wavelet processing, and the final sharpened planetary images.

Image 1 shows three photographs of Jupiter arranged vertically, taken approximately one hour apart. The planet’s rotation is clearly visible through the changing position of the Great Red Spot. In the top image the Red Spot appears on the left side of Jupiter’s disk, in the middle image it is near the center, and in the bottom image it has moved toward the right side. From this sequence, Jupiter’s rapid rotation can be visually estimated directly from the photographs.

Image 2 shows the same three Jupiter photographs, again arranged vertically for comparison. This layout makes the motion of the Great Red Spot even easier to follow and highlights how much Jupiter rotates over a short period of time. Since Jupiter completes one full rotation in roughly 10 hours, significant surface movement can be observed within a single night of planetary imaging.

This project demonstrates how effective planetary imaging can be even from a light-polluted city when using high-frame-rate video capture and stacking techniques. Jupiter’s cloud belts, polar shading, and the Great Red Spot are clearly visible thanks to careful capture timing and RegiStax processing during opposition.
