Can you guess which case is the AP180 ?? |
|
Here is the 180 f/9 next to my 155 f/7. As you can see, the AP180 is quite the APO.
|
|
1" doesn't sound like much, but the 180 is a good bit heftier than the 155.
|
|
It comes with a 2.7" focuser, and it is just as smooth as the new ones.
|
|
The AP180 even begins to make the Paramount ME look small. |
|
My ST-10XME gives me about 0.86"/pix, which is usually oversampled for my skies, while the FSQ-106N uses my ST-237A and produces almost the same FOV, but 2.88"/pix.
|
|
The Tak FSQ-106N looks tiny riding on top as the guidescope.
|
|
Andy Homeyer's custom rings for the FSQ allow the center of the FSQ-106N to be the same as the center of the AP180.
|
|
Losmandy plates added to the front and rear of the Versa-Plate allow for easy balancing and support of the water cooling lines. |
|
The combo requires 60lbs of counterweights, but the Paramount ME hardly knows they are there.
|
|
A custom made motorized focuser allows for precise focusing during the night.
|
|
It's even color coordinated to match the observatory !!.
|
|
Closing in on image time, and it looks like it's going to be a beautiful night. |
|
Image quality is what you would expect from a classic AP refractor.
