T8 - 106mm APO Refractor

Very Wide Field. Imaging Missions. Typically used for RGB & Narrowband Imaging. 

T8 is a 106mm Takahashi FSQ telescope based at SSO in Australia. It has a selection of RGB and Narrowband imaging filters. Its teamed with a sensitive FLI Microline CCD and a full house filter wheel.

T8 is a prime imaging platform in the southern hemisphere with exceptional optics and will be able to gather data of APOD winning quality.


T9 - 127mm APO Refractor

T9 is a wide-field imaging system dedicated to the astro-imager.

The flat-field, fast focal ratio, and short focal length of the NP127fli is a perfect match for the large CCD chip in it's FLI ProLine PL16803 camera. This Tele Vue telescope has superb optics.

Together they produce over a 3° field of beautifully sharp stars.


T12 - 106mm APO Refractor

Very Wide Field Telescope. Typically used for Wide Field RGB / Narrowband Imaging. FITS and TIF file formats. Dark Frame calibration data is available for  60, 120, 180, 300, 600, 900  second exposures. Binx1 - Binx2.

T12 features a high quality Grade 1 FLI CCD. Its Internal Off Axis (MOAG) guidance system can provide high accuracy during even long exposures.


T13 - 90mm APO Refractor

Typically used for imaging of wide field targets. One Shot Colour.

The T13 Telescope is also part of the iTelescope outreach program run in partnership with the ANU Research School for Astronomy & Astrophysics, to also be used by the general public as an educational tool.


T17 - 430mm Reflector

T17 is a Science Platform. Normally used for Science Missions, Deep Photometry, Narrowband and 'Extended Red' light IR imaging. It is equipped with a FLI ProLine E2V CCD47-10-1-109 CCD. that has 'extended red sensitivity' when compared to standard CCD’s. Giving it an almost 'Near Infrared' mission profile.

T17 is a unique telescope. T17 holds multiple world record achievements for the most distant objects imaged by amateur astronomers.  

T17 can detect extremely distant galaxies in 300 sec exposures. Some of its targets have been the most distant and oldest ever imaged on a publicly accessible telescope.

If you wanted to bring out stars hidden in nebula with its Helium filter or chase targets that are very faint, then this CCD will do the job. Its extremely sensitive, so much so that OVER exposure becomes an issue and users should take care since its CCD is of the NABG variety.

T17 is a valuable science asset to iTelescope Siding Spring Observatory. 


Telescope 30 - 500mm Reflector

Deep Field. Hybrid Missions. Typically used for Photometry and Imaging. 

The Planewave Ascension 200HR mount is so accurate whilst tracking that iTelescope Admin have disabled active guidance, with a corresponding decrease in session setup time when imaging.

Note: T30 is fitted with a very sensitive  Non Anti Blooming Gate (NABG) CCD. Beware of long exposures on moderate to bright stars or targets and use a bracket of short exposures or use software to repair any blooming artifacts.


T31 - 500mm Reflector

Deep Field. Hybrid Missions. Typically used for Photometry and Imaging.

T31 is fitted with a 0.66 Focal reducer.

The Planewave Ascension 200HR mount is so accurate whilst tracking that iTelescope Admin have disabled active guidance, with a corresponding decrease in session setup time when imaging.

T32 - 413mm Reflector

T32 features a Huge CCD chip with an amazingly wide FoV. Matched up with the wonderful Planewave mount this telescope can deliver incredable data. Note: VERY large FITs files - 32Mb Binx1

FITS and TIF file formats. Dark Frame calibration data is available for  60, 120, 180, 300 & 600 second exposures. Binx1 - Binx2.  ABG. Recommended Maximum Exposure 300 secs.

The Planewave Ascension 200HR mount is so accurate whilst tracking that iTelescope Admin have disabled active guidance, with a corresponding decrease in session setup time when imaging.


T33 - 400mm Reflector

T33 features a large CCD chip with a great FoV. Matched up with the wonderful Paramount PME mount and off axis guidance this telescope will deliver incredable data.

Due to the very fast optical design, a bright moon light may impact some exposures.  Select targets well away from the moon position and use narrowband filters for quality data during bright moon periods.

T33 is also best used on calm, low wind nights.

A 'point' is iTelescope currency. Your membership plan comes with a set number of points, When you join to a new plan or when your membership plan renews you accumulate 'points' in your account, and you can even buy additional points if you are running low.

Each telescope has an hourly imaging rate expressed in 'points per imaging hour', this is the cost of using one hour of exposure time on that given telescope. Each telescope has it own hourly rate, which is influenced by your membership plan and the illumination of the moon. Typically the higher the membership plan the lower the hourly imaging rate per telescope. You can find the telescope rates here and on the launchpad.

You exchange your accumulated points for imaging time on a telescope. 

Example: If the telescope rate is 50 points per imaging hour and you have 100 points in your account, this means that you have 2 hours of imaging time on that given telescope.

You only pay for the imaging time you use, if you take a 5 minutes exposure you only pay for 5 minutes of imaging time in points, each time you use a telescope you consume your points along the way, simple! 

Click the 'view membership plans' button below to see the imaging hour rate for each telescope for a given membership plan and moon illumination.



When your observing plan finishes, your account will be billed for the total exposure time you have used. If your observing plan contains 30 mins of imaging, thats all you will be charged, in most cases. Typically, you do not pay for slewing, focusing and pointing, etc.


As astronomers and imagers we all know that clouds and a gust of wind can spoil your observing session. We have made it simple for members to request a refund for a telescope session. You can now just follow the link from your email usage receipt or via the account history tab located in the launchpad. In most cases refunded points can be returned to your account instantly.

Approximate Time Example

Here is a simple example of how much imaging time you can approximately have on T3 when you first join a paid plan. These calculations assume you factor the 40 points you are initially provided with when you open your account. No moon is visible in the night sky, if the moon is present, your time would increase, up to double with a full moon.

Starter-Trial, approximately 1 hour of imaging time.
Plan-40, approximately 1.5 hours of imaging time.
Plan-90, approximately 2.5 hours of imaging time.
Plan-160 for example approximately 4.1 hours of imaging time.
Plan-290 for example approximately 7.3 hours of imaging time.
Plan-490 for example approximately 13.2 hours of imaging time.
Plan-1000 for example approximately 30.5 hours of imaging time.

You are not limited to T3 this is just an example. Paid memberships include full access to all telescopes, to view the hourly rate for a given telescope please visit the membership plan page.

Before connecting to a telescope we strongly recommend that you use Chrome or Firefox to connect to our telescopes. Both Safari and Microsoft Edge are currently not compatible with our systems.
