Celestron Powerseeker 60EQ OTA rings mod.

This is for my tower balcony 24/7 seeker. With heavy EPs it's asking for a significant OTA rebalancing often. The first solution was an OTA counterweight (3lb) sliding on H&L tension belts. This one is finally the ultimate solution for this classic small tube long refractor telescope:

Design details as follows.

SeeStar S50 trick: No leveling nor compass ever?

Being working on the Plate Solving project myself in the past, I've figured that SeeStar firmware implementation might follow a similar math for its functionality.

That led to a few simple experiments confirming that initially. After a few software updates from ZWO  rendering my initial findings obsolete I now have reworked my quick guide below.

ZWO SeeStar S50

I have decided to get this minimalistic but full fledged robotic astro-photo rig for occasional near zero effort sky events documenting and possibly astro-photometry, some astronomy apps development ideas benefiting my main aperture (Portaball 12.5), and remote terrestrial imaging.

Zero regrets! I believe it's on par with the venerable 100% manual AstroScan ball scope in the engineering ingenuity.

Orion 70mm Multi-Use Finder Scope

Just would like to share my impressions with this simple purchase.

At $100 it's somewhat overpriced for what it is indeed, as at the close inspection I have figured it's just the front piece of the Orion's 70mm binoculars plus the 6 adjustment screws shoe mount stalk and some threaded adapters. But overall it might worth it in the long run.

or The ultimate Telrad / QuInsight USB Power / Blinker Mod

Every light-producing telescope sighting device for astronomy use could benefit from the so called "Blinker" feature, which helps the observer to maintain the eyes darkness adaptation as much as possible during the telescope pointing flow with that type of finders simply reducing the light exposure. That allows to point with such a device using much fainter stars than with the reticle constantly shining into observer's eyes.

I had that "blinker mod" implemented over a decade ago using the trivial LM555 timer IC for my Telrad (you can easily google for that circuit and Telrad integration guides, there are plenty online). But as I have recently acquired the more advanced collimator sight the QuInsight I decided to make a more advanced blinker as well. But it turned out so advanced that I see it frankly opening the IoT era in amateur astronomy!
