The Telrad Pulser improves contrast by pulsing the reticle image on and off, thus aiding in the location of faint objects. It will also greatly increase the battery life for your Telrad. Following the simple instructions you can easily install the pulser in a short time. Once installed, the original control knob still controls the power and brightness, and the new control knob will control the pulse speed of the reticle image. You can vary the pulse frequency from very slow to having the reticle image constantly on.

Works as described.Pros: Cons: Comments:
I found it was easy to install, as long as you follow the instructions carefully, especially when putting the rheostat (switch) in place, which is where you really need to follow the instructions carefully, because it only goes in following the instructions. When it comes to finding objects in the night sky I like to use everything available, and I prefer the fun of finding objects without computers. The very slow pulse of the reticle is really nice.

Should be an included option on all Telrads.Pros:
Easy to Use,AccurateCons: Comments:
Works great. You have control over brightness and pulsing frequency. You have to cut battery leads and use provided twist connections. ( I soldered and used heat shrink ) You have to drill into the side housing, (template provided ) to fit the pulsing control, but be careful putting the battery pack back in. It is a tight fit with the installed pulse control circuit board installed. I had to enlarge the hole the control fits through and get the proper distance to the back wall of the housing. Worth the hassle though.

Makes the Telrad more usefulPros:
The Telrad should come with this for the amount they charge. That being said if you have a Telrad this is very useful. Be warned that it is a tight fit and you will have to drill a hole in just the right spot.

Easy to UseCons: Comments:
This is the second unit I bought. I ordered and installed the first one and liked it so much I had to put one on my other Telrad. You can adjust the brightness and the pulsing interval. Installation is a little tricky. It comes with a template to cut out and tape on the sideplate to drill the necessary hole and twist connections to attach the unit to the battery wires. I chose to solder and heat shrink the connections. One word of caution. It is necessary to drill the hole for the unit slightly oversize to get the adjustment shaft through and properly positioned so that the battery pack will fit without crushing into the chipboard. It's a tight fit,but the finished result is well worth the effort.

Easy to UseCons: Comments:
The installation went smoothly, albeit, the fit was tight. I used the axiom 'measure twice, cut once', and the unit fit perfectly. This unit is very useful for aiming at dim objects, or in light polluted skies. I'd imagine that the battery life will be extended, but haven't used it long enough to find out yet. The addition of the pulser brings the already excellent Telrad up a notch higher. I'd recommend it to all Telrad users that view in light polluted skies, or have difficulties aiming at dim objects.

Needed riffler files and a drill pressPros:
Lightweight,Easy to UseCons:
Operation is fine, but installation was awkward. Dimensions given on the instructions that came with the pulser didn't match the dimensons of the parts. AgenaAstro furnishes instructions that have better dimensions, but the potentiometer shaft and board are too large to slide into place even using the 5/16" shaft hole Agena specifies. To get the board and shaft into postion I had to angle the side of the hole with a file.

The icing on the cakePros:
Easy to Use,Lightweight,CompactCons: Comments:
This is an easy-to-install add-on which will make your telrad easier to use with faint guide stars. The instructions are complete and the installation only takes a few minutes, but don't rush. I have 2 telrads modified this way and they work very well. The old control still alters the brightness while the new one controls the blinking rate.

The ultimate Telrad upgradePros:
Easy to UseCons: Comments:
Easy to install and use. Infinite adjustment ability of the telrad reticle. Slow to fast pulsation or constant on AND barely visible up to brilliant brightness capabilities. Kudos to the genius of this Telrad innovation.

Improves finding targets,Easy to follow instructio,Easy conversion kitCons:
Pattern measurement offComments:
My eyesight is not good. This makes it much easier to find and center target in lenses. Only complaint is that drilling diagram measurement is off but not a big concern everyone just needs to be aware of it. Have shown it to friends and they love it.

Find the dim stuff faster and easierPros:
Easy assemblyCons: Comments:
Have you ever tried to star hop to that 6.5 magnitude star that is right next to NGC eleventy something but just can't quite get there? No matter how dim you make the telrad sight it still overpowers and washes out that dim star.
Enter the pulser. A friend had one of these on his Telrad and after trying it just once, I had to have one. It is so much easier to see the really dim stars while the led is off, then move the scope to that position when it is on. The rate of the blink is adjustable from full on to one blink every couple of seconds.
Installation is pretty straight forward with the one exception of drilling a hole 0.7 inches from one edge as indicated on the included instructions. 0.7 inches is just slightly more than 11/16 of an inch or slightly less than 3/4 of an inch. Either figure would have been easier to use than the 0.7 inches. Heck, I would have even taken metric measurements over that. That's 18mm for those who may need it. Installation was completed in under 15 minutes.
Bottom line: This was one of the best investments I made in astro stuff in the last several years.
