⚠️ Important Safety Information
Before performing any maintenance on your Sky-Watcher EQ6-R Pro, please read and understand
these safety guidelines:
- Optical Safety: Never clean optical surfaces unless absolutely necessary.
Improper cleaning can permanently damage coatings. - Chemical Safety: Use only approved optical cleaning solutions.
Never use household glass cleaners or alcohol-based products. - Solar Safety: Never look at the sun through your telescope or finder scope,
even when performing maintenance. - Equipment Safety: Keep track of all screws and small parts during maintenance.
Document their positions before removal.

SpaceX Rocket Launch Plume over California
What's happened to the sky? Last Monday, the photogenic launch plume from a SpaceX rocket launch created quite a spectacle over parts of southern California and Arizona. Looking at times like a giant space fish, the impressive rocket launch from Vandenberg Air Force Base near Lompoc, California, was so bright because it was backlit by the setting Sun. The Falcon 9 rocket successfully delivered to low Earth orbit 23 Starlink communications satellites. The plume from the first stage is seen on the right, while the soaring upper stage rocket is seen at the apex of the plume toward the left. Venus appears at the top of the frame, while a bright streetlight shines on the far right. The featured image was captured toward the west after sunset from near Phoenix, Arizona.

About Optical Coatings
Your Sky-Watcher EQ6-R Pro uses coatings
for optimal light transmission. These coatings are delicate and require special care:
- Never use cleaning solutions not specifically approved for coated optics
- Avoid touching coated surfaces
- Clean only when necessary
- Use minimal pressure when cleaning
- Watch for signs of coating wear
Dew Prevention and Management
- Use a dew shield during observations
- Consider a dew heater for long sessions
- Allow telescope to acclimate to outdoor temperature
- Never store telescope while dew is present
- Use desiccant in storage case
Storage Requirements
Optimal Storage Conditions
Temperature
10-30°C (50-86°F)
- Avoid extreme temperatures
- Prevent rapid temperature changes
- Keep away from heat sources
Humidity
30-50% Relative Humidity
- Use desiccant packs
- Monitor humidity levels
- Replace desiccant regularly
Environment
Clean, Dry Space
- Avoid dusty areas
- Keep away from windows
- Use climate control if possible
Position
Proper Orientation
- Store tube horizontally
- Support at multiple points
