Do you want to use longer exposures to photograph fainter objects? Without tracking control, you’ll notice star trails in your image!

👉 Solution: Guiding

➡️ Options:

1️⃣ Autoguiding: The most common and easiest method.
➡️ We need:
▶️ Guide scope
🔗 https://ow.ly/GMkS50Yk68J
▶️ Alternatively: Off-axis guider
🔗 https://ow.ly/ayj850Yk68M
▶️ Guiding camera
🔗 https://ow.ly/jfhX50Yk68L
▶️ Camera for imaging
🔗 https://ow.ly/qsv150Yk6kp

➡️ The guiding camera is mounted at the end of the guide scope or off-axis guider and connected to a GoTo mount via an ST-4 cable. The task of the autoguider: track a guide star and immediately send a correction command to the mount if there is any deviation. The astro camera is mounted at the end of the telescope as usual and connected to your laptop via USB.

2️⃣: Manual guiding with a guide scope or off-axis guider. A more complex but more affordable method.

➡️ We need:
▶️ Guide scope or off-axis guider
▶️ Diagonal mirror or Amici prism (only when using a guide scope)
🔗 https://ow.ly/A8gr50Yk68O
▶️ Reticle eyepiece:
🔗 https://ow.ly/Reks50Yk68N

➡️ First determine where the right ascension direction is in the eyepiece. Then rotate the reticle eyepiece in the focuser until the crosshair aligns in the same direction (east-west). This gives you good orientation and lets you know which buttons to press if the selected guide star drifts.

🌔 On the evening of 26 May we can see the Golden Handle on the Moon. It appears when the waxing Moon is exactly 83 percent illuminated. About 10 days after new Moon the time has come. The light phenomenon occurs and on the dark side of the light–shadow boundary on the Moon, a handle shape emerges. 🫖

💥 Airbag gas generator as a civilian by-product of solid rocket fuel technology

🚀 Solid rocket – explained briefly
A solid rocket motor contains a solid propellant made up of fuel and oxidizer. Both are already mixed. Once ignited, the propellant burns evenly, producing a gas which, according to Newton’s laws (action/reaction), generates thrust. Solid rockets are known for their simplicity, reliability and storability – but they face challenges when it comes to thrust control.

⛽ Liquid rocket – the opposite
Here, fuel and oxidizer are stored separately and only mixed together in the combustion chamber. Thanks to the controlled fuel flow, thrust can be regulated, but the technology behind it is more complex and expensive.

🚗 The airbag as a by-product
The airbag uses exactly this principle of solid fuel technology. In the event of a severe impact, the solid propellant is electrically ignited. Within just a few milliseconds, almost pure nitrogen is produced under high pressure. The airbag inflates explosively and cushions the head.

💡 Fun Fact
Despite the huge safety benefit, airbags are not legally required in Germany – even though they have been installed since 1981 and are now part of the standard equipment in every car. In the USA, however, they have been mandatory since 1997.

🌙✨ When twilight falls on 19 May, an inviting meeting in the sky awaits us. Low above the western horizon, around 10 p.m., three striking celestial bodies gather in the constellation Gemini: the Moon, Venus and Jupiter.

The Moon appears as a delicate waxing crescent, illuminated by only about 13 percent. To its right shines Venus, the brightest planet in the night sky. On the other side, Jupiter glows with a slightly yellowish light. With a magnitude of –3.9, Venus clearly outshines the gas giant, which still reaches –1.9 mag. A direct comparison of these two planets is rarely this easy. The scene is especially beautiful during evening twilight – a perfect backdrop for a photo. 📷

Want to explore the moon but don't know where to start? 🌚
👉 We'll show you three highlights on the edge of the moon!

🌋 Langrenus
- Ring of mountains on the eastern edge of Mare Fecunditatis*
- Diameter: 132 km
- Depth: 4,300 m
- Contains a central mountain range with two main peaks
- The bottom of the crater is flooded with lava
- Beautiful contrast to Langrenus in the north-west: trio consisting of the craters Atwood (29 km), Bilharz (43 km) and Naonobu (35 km)

* ‘Sea of the Moon’ on the side of the moon facing Earth

⛰️ Petavius
- Ring mountain range at the southern end of Mare Fecunditatis
- Diameter: approx. 180 km
- Depth: west 3300 m; east 1800 m
- Special features:
> Southwestern wall hangs split into two separate ridges. This creates a ring within a ring.
> Also in the southwest: Petavius rilles – visible as a thin black line on the morning terminator* and as a bright line on the evening terminator*.

* Day-night boundary on the Moon. When the Moon is waxing, the Sun rises in this area (morning terminator) and when the Moon is waning, the Sun sets there (evening terminator).

🔦 Beam of light in Hyginus
- Best visibility about 7 days after the new moon (we recommend a high magnification of about 200x)
- Wedge of light on the shadow-covered crater floor
- Sun shines through the Rima Hyginus*

* Two-part groove interrupted by the crater ‘Hyginus’. Probably once a lava channel.

The Moon loves to pay our night sky a visit every now and then. 🌍
On 14 May, the thin crescent Moon calls in on Saturn. Encounters like this are a truly beautiful sight. ✨
They’re also a perfect chance to capture a mood shot with a stationary camera and lens. 📷
In the early morning you’ll need a clear view of the eastern horizon.

Our sun 🌞

Did you know that this summer in Europe we can once again look forward to a partial solar eclipse – and in some regions even a total one? 😎
Here’s a little warm-up of our home star in all its glory, captured by Cristian Fattinanzi.

👉 Here are all the details at a glance:
🔭 Telescope: Coronado ST 60/400 SolarMax II
📷 Camera: ToupTek G3M224C

Do you also have great shots? 📸
👉 Then tag us in your posts or send us a DM – we look forward to your astrophotos! 😊

Since the Earth rotates, every object moves ¼ of a degree westward per minute. To avoid star trails, tracking is therefore essential. With a 50 mm lens, you can expose for about 10 seconds before a star is no longer rendered as a pinpoint. The longer the focal length, the shorter the exposure time must be.

➡️ The following mounts are recommended:

1️⃣ Retrofitting a motor to a non-motorised equatorial mount
🔗 https://ow.ly/JJ2350Y7pxU

2️⃣ Motorised, equatorial travel mounts
▶️ We recommend our specially developed Omegon MiniTrack:

3️⃣ Equatorial mounts with GoTo (available at astroshop.eu)
🔗 https://ow.ly/QtRl50Y7pxV

💡 Note: When using an alt-azimuth mount that tracks on both axes, field rotation may occur at long focal lengths and long exposure times. This effect can sometimes be corrected later during image processing.
