StarryCamera2 vs GearBoxTimer

This camera app is designed to help you take beautiful photos of the stars with your iPhone. Why not try shooting star trails with your iPhone? ### How to Use 1. Go to a location with low temperatures where stars are clearly visible. 2. Secure your iPhone on a tripod or similar mount (this is the most important step). 3. Select a shooting mode. 4. Adjust brightness using shutter speed and ISO sensitivity. 5. Press the shutter button. ### Mode Features Starry Sky: Makes bright stars stand out; captures the scene close to how the naked eye sees it. Star Trails: For capturing star trail photos (shooting for 30 minutes creates a distinct star trail effect). Milky Way: For capturing the Milky Way and fine stars with sharp clarity. Night View: For when you want no processing; produces low-noise images. Lighten Composite: Uses lighten compositing (ideal for fireflies, fireworks, light trails, etc.). ### Fine-Tuning Focus 1. Position a bright star (such as a first- or second-magnitude star) in the center of the screen. 2. Press the focus button to zoom in; use the slider for coarse adjustment, then use the stepper controls to find the position where the star appears smallest. 3. If it is difficult to tell, try shooting with different focus positions and compare the results. ### About Star Trail Mode Unlike other modes, Star Trail Mode and Lighten Composite Mode do not allow brightness adjustments via shutter speed; please adjust the brightness using ISO sensitivity instead. To minimize errors, start with a 120-second test shot to adjust settings like ISO sensitivity before proceeding to the actual 1,800- or 3,600-second exposure. The "Starry Sky" mode is suitable for urban astrophotography, as it allows you to capture images in locations where long exposures might otherwise result in an overexposed, washed-out white image. Including statues or monuments in the frame can create impressive, visually striking photos. Using flimsy holders or tripods can cause the star trails to blur, so I recommend using sturdy, high-quality equipment. In "Star Trail" mode, the background is smoothed out via "Lighten Composite" (stacking) processing; this improves the visual quality, even on cameras with small, noise-prone sensors like those found in iPhones. Including the North Star enhances the swirling effect but results in shorter trails. Pointing the camera east (or elsewhere) eliminates the swirling look but produces longer trails. Choose whichever style you prefer. During a meteor shower, a one-hour star trail exposure might capture two or three shooting stars. For "Star Trail" mode, I recommend setting the light duration to "Middle Only." ### About Watermarks The default setting displays the app's name; please customize this with your handle or account name to protect your copyright. ### Recommended Method for Star Trail Photos with Cars 1. Start by selecting the ISO setting one step below the maximum. 2. In the settings, select "Middle Only" for the light duration. 3. Set the light intensity to "Medium" on the shooting screen. 4. Set the shutter speed to 120 seconds and take a few test shots to adjust the ISO sensitivity and light intensity. If the entire image is too bright, lower the ISO sensitivity; if it is too dark, raise it. If the car illuminated by the light is too bright, lower the light intensity; if it is too dark, raise it. 5. Once the ISO and light settings are finalized, set the shutter speed to 1800 seconds for the actual shot. Initially, you can leave the focus at the default setting of 0.0; however, once you get the hang of it, pressing the focus button to ensure precise focusing will result in sharper star trails and higher-quality photos.

GearBoxTimerは、天体撮影機器制御ツールGearBoxに接続してインターバル撮影を実行する天体撮影アプリです。 撮影には別売りのGearBoxが必要になります。 ○使い方 1. カメラを接続したGearBoxのWi-Fiに接続し、アプリから接続します。 2. 基準となる露出設定と撮影時間を設定し、GearBoxに送信します。 3. 撮影中はGearBoxのWi-Fiから切断しても、再接続すれば自動的に現在進行中の撮影状態を確認できます。 ○対応機種 ・Canon EOS R / EOS RP / EOS Ra / EOS R3 / EOS R6 / EOS R6 Mark II / EOS R7 / EOS R8 / EOS R10 / EOS R50 / EOS R100 EOS-1D Mark III / EOS-1D Mark IV / EOS-1D X / EOS-1D X Mark II / EOS-1D X Mark III / EOS-1Ds Mark III EOS 5D Mark II / EOS 5D Mark III / EOS 5D Mark IV / EOS 5Ds / EOS 5Ds R / EOS 6D / EOS 6D Mark II / EOS 7D / EOS 7D Mark II EOS 40D / EOS 50D / EOS 60D / EOS 60Da / EOS 70D / EOS 80D / EOS 90D EOS Kiss F / EOS Kiss M / EOS Kiss M2 / EOS Kiss X2 / EOS Kiss X3 / EOS Kiss X4 / EOS Kiss X5 / EOS Kiss X6i / EOS Kiss X7 / EOS Kiss X7i / EOS Kiss X8i / EOS Kiss X9 / EOS Kiss X9i / EOS Kiss X10 / EOS Kiss X10i / EOS Kiss X50 / EOS Kiss X70 / EOS Kiss X80 / EOS Kiss X90 / EOS M200 ・FUJIFILM X-Pro3 / X-T3 / X-T4 / X-S10 ・Nikon Z5 / Z5II / Z6 / Z6II / Z7 / Z7II / Z9 / Z50 D4S / D5 / D6 D500 / D610 / D750 / D780 / D800 / D800E / D810 / D810A / D850 D5300 / D5500 / D5600 / D7100 / D7500 ・SONY α1 / α7C / α7S III / α7R IV / α7R V / α9 II / α6700
