[SOLD] Etx-125 uhtc ota

[tonybarry (Tony)]

I have an ETX 125 optical tube assembly with ultra high contrast coatings, for sale.

It is the dark blue tube (not the pink printed tube). Diameter = 127mm, f/15, Maksutov-Cassegrain optics, with an inbuilt flip-mirror for either right-angle viewing or axial viewing.

The corrector is not perfectly blemish free - there is one "spot" of about 2mm, at the 9 o'clock position, which is resistant to a dust blower, and a concentric line and smudge at about 11 o'clock which looks to be of the same aetiology. I have not tried to clean either of these marks. You can see them in the photographs below.

I obtained the OTA + mount about six months ago from a fellow Ice-InSpace member, intending it to be a grab and go scope for lunar occultations, but it has not seen starlight (or moonlight).

I have instead cannibalised the mount for other purposes, and so the OTA is available for an interested Ice-In-Space member to acquire.

Price $200 + post (but pickup from Western Sydney would be preferred).

Email to tonybarry2008 AT mac DOT com NO DOT AU in the first instance, or PM here at Ice-In-Space.

Regards,
Tony Barry

Tony are u able to tell me the weight of the tube (and mounting plate if it has one). I am still looking around for a good photo scope to go on an iOptron cube but the weight limit is 5kg.

Hi Trevor,

The weight (with corrector cover and eyepiece cover) is 3.03kg. The mount point is a flat area 50 x 70 mm (approx) with two 1/4" threads, visible in the second picture.
