Small Accessories Pouch
Loop a zippered pouch around the tripods center large knob and fasten with a plastic clothes clip for easy removal. The bag will hold small accessories to include the tiny leveler, other optics and misc. items that don't fit the center tray. The bag hangs in the center of the tripod and increases stability.

Install a New Weightless Finderscope
(see photos) At about $5 from China, the nearly weightless black 80EQ 5x24 standard optical refractor finderscope (with mount, lenses, crosshairs, and focusable EP) is made by Celestron. Because this unit is all plastic with resin lenses, the weight is almost nothing and it has none of the challenges the red dot finder has which currently lists for $23.95. It comes with a mount for adjusting the finderscope with three setscrews.
New Celestron AC Adaptor Accessory
The telescope has no AC power adapter. Eight AA batteries (not included) are short lived. Non rechargeables don't work because they rate at 1.2 volts and eight would fall short of the recommended 12 volts. The recommended adapter does not have enough power to drive the telescope and all accessories. Therefore a 5 amp
Celestron adapter was purchased, item number 18780. It can handle astro imaging and additional equipment. In the future, this may include a dew heater, imager, focuser, etc. 

Routing the Power Cable
The barrel on the DC plug is supposed to thread directly onto the mounts power jack and prevent accidental power out from a cable pull out. However, the mount's jack is recessed too far into the telescope's mount and the DC plug won't thread onto it. To fix this, the power cord is wrapped once around the base of the mount arm with a small loop. This allows the cord to follow the mount and the DC plug won't pull out.

Red Dot Finder
The red dot finder was removed as it did not fit onto the slide mount already on the OTA. It was replaced with a lighter weight Celestron standard finderscope with crosshairs.






Japanese Hand Warmer
Try this Japanese hand warmer. Just open a packet and shake to activate. Provides a lukewarm heat for 24 hours. Works perfectly when equalizing the thermodynamic temperature differences between outdoors and indoors, or working outdoors.

Stop Light Pollution
The light pollution may be created by your own residence. Tall skyscrapers have a habit of turning on automatic timer lighting located high above outside decks. These lights are designed to make the skyscraper look beautiful at night. Typical residences have lighting on at 6:30 pm and off at 9:30 pm. Contact an electrician to have these lights and/or timer turned off. The good news is these lights are usually low wattage, around 15, so not very bright and they are hung on the bottom side of exterior deck small roof overhangs, so they are reachable though reaching one has a certain amount of risk. On the other hand, they are located on a small overhead overhang where the telescope never points, is easily shielded or just don't observe between 6:30 and 9:30 pm or whatever timing they have set. Generally they are somewhat insignificant when observing the Moon and planets at lower elevations and the light could be filtered out with a light pollution filter. When the telescope is positioned indoors for through window observing, the light may be automatically shielded and never seen.
