Recommended Gear:

Planetary imaging is a specialized branch of astrophotography focused on celestial bodies within our solar system, such as Jupiter, Saturn, Mars, and the Moon. Unlike deep-sky imaging, which targets faint distant objects, planetary photography aims to capture fine surface details – Jupiter’s Great Red Spot, Saturn’s rings, and lunar craters. 

Since planets are relatively bright but heavily affected by atmospheric turbulence, astrophotography techniques like short exposures, high frame rate video recording, and post-stacking are used to counteract atmospheric distortion and produce sharp images.

Think planets are just quiet little dots in the night sky? Think again! They're actually the “hyperactive kids” of the cosmos. Jupiter completes a full rotation in just 10 hours. Its Great Red Spot is like a hamster on a treadmill. If you don’t capture it quickly, it spins away! You’ll need high-speed shooting (60–200 FPS) to freeze the detail. Also, turbulent air makes stars and planets wobble like jelly underwater.

The fix? Record high frame rate videos (typically 60–200 FPS), extract 1000+ frames, then let the software automatically select the top 10% to synthesize a crystal-clear image (a method known as “lucky imaging”).

Planetary Imaging is beginner-friendly for amateur astrophotographers. It works even in city light pollution as planets shine like bulbs. Additionally, the entry barrier to planetary imaging is low. A 114mm telescope + a modded DSLR or ToupTek Astro budget-friendly planetary camera is all you need.

Budget-friendly and High-quality Picks

1. Telescope

Since planetary angular sizes are small (e.g., Jupiter \~50 arcseconds), long focal lengths are key to resolving detail. Recommended types:

  • Mak/SCT Telescopes: F-ratio ≥ f/10, portable with stable collimation. Their closed tube design minimizes air turbulence, improving adaptability to varying seeing conditions.

  • Newtonian Reflectors: Great performance-to-price ratio but require regular collimation.

  • Refractors: APO triplet refractors deliver razor-sharp images but come at a premium price.

Recommended Aperture: ≥150mm - larger apertures gather more light, enabling better resolution of features like Jupiter’s bands.

2. Equatorial Mount: the Anti-shake Champion

The main purpose of using an equatorial mount is to counteract Earth's rotation (\~15° per hour). Top choice:

  • Motorized Alt-Az Mounts: Lightweight and user-friendly for visual and basic imaging.

4. Essential Accessories

  • Barlow Lens: The telescope’s zoom lens. A 2x Barlow instantly doubles Mars’ size! Tip: Pixel size (μm) × 5 ≈ ideal F-ratio. For instance, a 3.75μm camera (e.g., ToupTek Astro G3M662C) pairs best with ≤7.5x Barlow.
  • Electric Focuser: Using ToupTek Astro AAF to avoid hand-shake during focusing.

Astrophotography Planetary Imaging

  • ADC (Atmospheric Dispersion Corrector): Fixes planet “rainbow fringing,” especially effective when altitude <45° (Saturn’s rings stay clean!).

  • 1.25" Extension Tube: Adds 20mm of focus travel - perfect when your focuser falls short.
  • 12V Power Bank: 10Ah+ recommended for 6 hours of field use with mount+camera (no more mid-session shutdowns).

24 Hours Before Imaging:

  • Golden Window: Time your shoot around planetary opposition (closest approach to Earth; Mars appears 7x larger!).
  • Thermal Equilibrium: Move the scope outdoors 2 hours early to equalize temperature and prevent dew/fog. Metallic tubes especially need time to cool down. 
  • Ideal Weather: Pick a calm, clear night with planets above 30° altitude to minimize atmospheric distortion.
  • Top Apps:
    • SkyWalker Pro: Look for seeing <1.5 arcseconds + wind <15km/h = dream conditions.

    • Stellarium: Simulate planetary positions and plan your framing in advance.

Imaging Night Playbook:

  • Focus Like a Pro: Use a bright star + Bahtinov mask. Success = symmetrical diffraction spikes ().
  • Tools: SharpCap and FireCapture are popular tools for planetary imaging. Alternatively, you can use ToupSky, a self-developed astrophotography processing software from ToupTek Astro. In ToupSky, just enable the “Sharpness Index". The higher numbers mean crisper focus.
  • Optimal Settings: Pay attention to the brightness of individual frames during exposure. It's okay to slightly underexpose them. Adjust accordingly based on the planet's actual brightness during shooting. Gain control also requires careful attention - avoid letting noise become too prominent. For Jupiter, set the gain between 30-120, aiming for a histogram peak around 75%. Saturn can tolerate a slightly higher gain.
  • Recording Duration: For fast-rotating targets like Jupiter, keep each capture sequence under 3 minutes. Excessive recording duration will cause the stacking software to align surface features from different rotational positions, resulting in blurred details during post-processing.
  • Avoid Mistakes: 
    • Polar alignment: First, align the equatorial mount with Polaris. While planetary imaging has lower tracking requirements than deep-sky photography, proper polar alignment reduces field rotation during extended sessions and minimizes image drift.
    • Test shoot: take a 30-second test shoot before formal imaging. This checks for clouds, aircraft interference, and verifies if exposure settings are appropriate.
    • Stable setup: Choose a solid foundation away from vibration sources. Prefer ground-level locations over high-risk buildings to avoid structural vibrations. Opt for a concrete surface rather than wooden floors to prevent vibrations from foot traffic.

Post-Processing: Turn Raw Clips into Masterpieces

1. Stacking: Use AutoStakkert to auto-select the top frames. Jupiter = top 10–20%, Saturn = up to 30%.

2. Sharpening Tricks: Using RegiStax6: Layer 1 = enhance bands, Layer 2 = bring out texture, Layer 3 = use with caution (noise alert!).

3. Color Grading Tips: Avoid over-saturation - don’t turn Saturn into a lemon. A soft yellow haze looks more authentic.

 

Advanced Techniques

Use Monochrome Camera and Filter Wheel: LRGB Imaging for Max Resolution

Monochrome sensors skip the Bayer matrix, capturing pure luminance per pixel. Shooting in L (luminance), R (Red), G (Green), and B (Blue) channels separately, then combining, boosts resolution by 30%+, which is perfect for Jupiter’s belts and Saturn’s ring gaps.

How to Do It:

  • Hardware Setup:
    • Camera: ToupTek Astro G3M series mono camera 
    • Filter Wheel: ToupTek Astro 36mm, 1.25",2” filter wheels
    • Filters: ToupTek Astro 36mm, 1.25",2” filter wheels LRGB filter sets
  • Shooting Sequence:Record  90s per channel in order: L→R→G→B (\~5000 frames/channel)
  • Alignment & Synthesis: Use WinJUPOS’s \[De-rotation of R/G/B frames] to correct for rotation. Ctrl+H removes field rotation from tracking errors.

  • Color Accuracy Check: In Photoshop, verify histogram peaks for all channels aligh pre-composition.

Rotation Correction (WinJUPOS): Full Disk Imaging Without Blur

Because Jupiter rotates 15°/hour, clips>3 minutes blur features.  WinJUPOS models planetary rotation and aligns multiple video segments in reverse rotation, stitching them into a sharp global image.

Step Workflow:

  • Pre-process: Stack each video in AutoStakkert export as TIFF (retain full resolution). 
  • Import to WinJUPOS:
    • Go to \[Recording]\[Image Measurement]
    • Accurate UTC timestamp + lat/lon (error <0.01°)
