Explore Scientific 50mm Finder Scope Rings “ Tall

$74.99
SKU FNDRRGSTALL

Description

Explore Scientific finderscope rings are all made for 50mm finders. Choose from a classic low profile bracket (about an inch tall), one that is a tad higher (1.5") or a high profile bracket that stands 4" above the finderscope base.

Regardless of the height you choose, these brackets have two rings to hold your finder firmly yet gently, and each ring has three adjustment points. Heavy-duty plastic thumbscrews are included, and have large heads for easy adjustment even if you’re wearing gloves.

Because your telescope may not fit in its case with the finderscope attached, you will appreciate the quick release feature on Explore Scientific finder brackets. The bracket itself dovetails into the finder base (sold separately), and locks down with thumbscrews. It is a simple thing to remove or install your finder and bracket on your telescope in this manner.

To install your finder into the bracket, simply back the thumbscrews out so that you’ve opened up the full inside diameter of the rings. Slide the finder into place, and adjust the screws inward until your finderscope is securely held in position. You should have very rough alignment at this point, which means when you look through the finder and center an object, and then look through a low power eyepiece inserted in your telescope diagonal or focuser, that object will most likely be in the field of view, but not at or near the center (unless you are very lucky!). Doing that first fine alignment…the task of matching what’s in your finder to what’s in your eyepiece…can be tedious and frustrating sometimes, but once you complete the job, it should never be required again. Sure, you will have to tweak the adjustment every time you re-install the finder/bracket combo onto your telescope, but it should be fairly quick and simple.

Here is a helpful hint when it comes time to do that first alignment. Set your telescope up in the daytime, and make sure you bring out a variety of eyepieces with you. Find an easy target that is relatively far away, like a streetlight or the top of a telephone pole. Starting with the lowest power eyepiece, adjust your finder bracket until you have “matchingâ€

Exceptional Mount

A couple of years ago, I wanted to replace my old VMA200 mount with something more modern.
While visiting the Paris Astronomy show (RCE 2012) I noticed the Nova120. At that time, it was a brand new offering that I have not seen before, hence my hesitation to purchase
I wanted to purchase a E.U product to guarantee the quality and ease of access to support in my own language. I checked the forums and heard nothing but good things about the Nova120 so I decided to purchase it.

I have used enough astronomical instruments in the last 30 years to know what great quality is. The Nova120 coupled with the PRISM v10 and a CDK20 (508 mm) helped me pull off 900s unguided images with great ease. (Raw FITS File here). Payload of this setup is about 80 kg (160 lb).

The dizzying slew speeds, excellent accuracy and painless tracking makes this hobby easy and enjoyable again.
After using this setup for a year and a half, the only problem I had was rebalacing the gear after changing scopes. The superb electronics and software included make this tasks even more easier that just eyeballing the scope for movement due to unbalance.

You can very easily watch the motor consumption and know where the unbalance is....that easy. I have so much data that it is becoming difficult yo keep up.
I have absolutely zero regrets, this purchase has made everything easier: No summer/winter worm-gear adjustments, no guiding... just start imaging night after night after night.

Imaging Made Easy

Prism is my GoTo program for observatory control and imaging. Prism's many features make imaging taking a breeze.

I was concerned about giving Prism a try , especially as its quite expensive. So far Im very impressed and glad of my decision.
Im a beginner at all this so haven't tried other more recommended software, Prism appealed as it seems to do everything instead of using several programs 👍🏻

Great lightweight guide scope

This guide scope replaces a 400/80 that was waaay too heavy for what it did. The smaller 60mm scope does a great job guiding and I can RA balance with just one counter weight now - much better - and it looks like something Ferrari designed

Still learning Prism using Wireless links...

I have much of your software working at this time... I have it parked on my main computer, and a notebook... My main computer is a OverClock computer with 32 Gigs of RAM Clocking presently at 4400MHz with software parked on SSD drives... The rotation dome by NexDome is still not working... Most problems like this have to do with ASCOM Drivers... There is not very much detail information on how to use this software... I have to feel my way to a total operational staus... Second issue... The rain in the San Francisco Bay Area this year has limited my access to my larger telescope (12 inch SCT)... This rain has been so significant, I was force to weatherize my observatory... My goal here is,,, I am trying to remotely control my observatory totally. I have used Netgear Powerline 2000 to handle camera images and discover controlling rules to do that... High speed is vital for images with cameras over 3 Megs... I have both 12 Mega sensors and 24 Mega sensors... I am also using Netgear Nighthawk router and its mating extender to increase control signals to my observatory that is about 100 feet on the side of hill... I am also using Virtual Here software on a Raspberry Pi inside the observatory to solve the USB interface requirements... I started out using Model B and B+ on level 3 raspberry Pi's... I have moved to Level 4 Raspberry Pi to gain access to USB 3.0 technology... Big difference! I hope by early spring to have everything working... Bob Ritter MicTechS
