If those extension tubes came with the telescope (they appear to be ES extension tubes), then they fit on your scope. You need to unscrew the collar from the back end of the focuser tube and then scre

I should also add that with your type of T2 adapter, you should be at 55mm now. It appears as though your T2 adapter already has the correct length of backfocus length to go with your camera's lens fl

You need to check the website where you purchased the field flattener. That is usually where you will find the specs for required backfocus. Typically, however, this is 55mm give or take a little bit

I agree with you about finding objects that aren't solar system objects or Messier objects. This, in my opinion, is a weak area of the app. What if someone doesn't know the names of things to view? Wo

Tracking at the zenith or very near the zenith with any equatorial mount is troublesome. Even when trying to slew manually, by hand, it is very difficult to get it right. That being said, this looks m

I second the need for a lighter, much lighter, counterweight. The 9.9 lb counterweight will be far too heavy for just a camera. Patrick

I'm not sure which rule of the Cloudy Nights forum Jerry is referring to about Vendors not being allowed to comment on products but, there is an obvious downside to doing so. For example, I now have n

Power supply problems is the first thing to check after all else that you have already checked. If using a battery of some sort, a low battery will often cause one axis to drop out first. The next pos

I also need extra counterweights for my iEXOS-100 so I've been checking the ES website monthly since I purchased the mount (Dec, 2019) but have yet to see the black counterweights in stock. It is poss

Stellarium works fine without the need for the quirky and unstable Stellarium Scope now and for the past few months. However, make sure you are still using the current version of ASCOM Platform and no

I haven't tried it myself but, last I heard, Stellarium Scope is no longer needed for telescope control in Stellarium. The newest version(s) of Stellarium eliminate the need to use Stellarium Scope. I

I had the same idea and made my own adapter to fit the iEXOS-100 to my EXOS-2 tripod and my permanent pier. This homemade adapter worked just fine although without any fine azimuth control but I have

Okay, Jerry, clearly I misunderstood. Thanks for clarifying. With the multiple references to needing to purchase an ST-2, at a minimum, I misunderstood what you wrote. Patrick

In the poll, I answered that I would pay over $25 for the upgrade because that was the 'most correct' answer for my thoughts on this so I felt I should add my thoughts here. That being said, having pu

The pricing seems reasonable to me so I have no complaints there. The purpose of the iEXOS-100 was to provide a high quality mount that is lightweight and portable. The iEXOS-100 in its original confi

What is an ST2 or ST3 tripod? I went to the Explore Scientific website and can't find any tripods at all nevermind tripods named ST2/3. Patrick

Is the tripod for the EXOS-2GT non-PMC the same as the PMC version? If they are the same, the Orion pier extension will work with minor adaptation. If I remember correctly, you just need to file down
