Marc, If you had said that you were having mechanical issues (you probably did at some point and I missed it) then I would have directed you to send it back to us for adjustment/replacement as require

I really don't appreciate your threats to go back to Amex and OPT to get a full refund without you demonstrating an ounce of due diligence to get your system working. I don't really know what you woul

Hi chaps, some advice from you experienced DSLR astro photographers if possible please.... I am using a Cannon EOS1300D DSLR on my IEXOS 100 mount. The camera I picked up second hand and it came with

Brian You need to get a long focal length lens. My guess is it would be less expensive to buy a telescope and use it as a prime lens. It will also have the advantage of less glass (optical loss) great

#iEXOS-100

Hi Brian... Wes is correct if you want to go long focal length such as into the 400+mm range. In that case, it is probably less expensive to get a good 420mm telescope (ie, Skywatcher Evostar ED 72mm)

There is a lot you can do with just lenses. I started with lenses and I am still a big fan. Lenses have the distinct advantage is that you can use them for daytime photography. . Last night I tried my

I would caution you that even though the weight limit will support the longer focal length scopes, our general advice for the iEXOS 100 mount is to not exceed 400 mm in focal length because even when

#iEXOS-100

Right Jerry, good advice. The ST-80, and most other 80mm f5 scopes of course have a 400mm fl. But the danged camera sensor can make things longer if it is a cropped sensor like a DX in Nikons. In that

Howdy, Probably the previously owned lens was defective when you bought it? You could always send it back to Sigma and have them inspect it. They have a firmware update as well. I have four setups for

I am going to skip the Polemaster, with the thought to using the guidescope & Sharpcap to align. I will also be getting the ASIAIR, but the intention of that use is farther away. So far now it would j

Sean, I can't speak to the iExos-100, and the payload you propose, as I don't have one. There are certainly examples here, of that mount performing much better than you'd expect for its size - but jus

I was originally going to get just a field flattener, but I took a look at using the Orion .8 focal reducer, which using Astronomy Tools site tells me I would get to 408mm focal length. That should be
