ATT 2024 wrap-up - RASA promotion: Celestron RASA 8" on AVX GoTo mount with StarSense autoguider

Celestron Advanced VX 8" RASA Bundle

The ideal astrophoto combination of RASA 8", AVX mount and StarSense autoguider

Celestron 8" Rowe-Ackermann Schmidt-Astrograph - fast Deep-Sky Photo Telescope
The compact 8" Rowe-Ackermann Schmidt astrograph was developed by Celestron as complete telescope for astrophotography. Make spectacular wide field images with high resolution and ultra-short exposure time. The 8" RSA is optimized for mirrorless system cameras and, of course, for astro cameras like the ones from ZWO. The astrograph is not suitable for classic DSLR cameras, as their flange focal distance is too long.

Most important features of the 8" f/2 RASA:

The RASA provides a corrected image field with 32 mm diameter.

A built-in fan speeds up cooling down, thus the RASA becomes fully operational after relatively short time.

The primary mirror is held by stable roller bearings, so unintentional readjustment is excluded. Now focusing is more accurate and simple than ever before.

The RASA 8" is designed for the most up-to-date cameras like mirrorless system cameras and, of course, astrocameras up to 25 mm flange focal distance. The adaption to T2 is included in the scope of delivery. Fine tuning is made with T2 adapters from Teleskop-Service.

The Advanced VX GoTo mount from CelestronThe AVX is the ideal mount for the 8" RASA astrograph. It can be set up in minutes and polar alignment is just as easy. Thanks to the PEC (Periodic Error Correction) you have an accurate tracking that makes guiding unnecessary.


The equatorial GoTo mount AVX from Celestron:

The equatorial GoTo mount Advanced VX carries the RASA with very good stability. It also offers performance reserves for accessories like heavy CCD cameras and guide scopes. We recommend this mount especially for astrophotography because of its accurate tracking. The mount automatically positions any object in the sky. There are over 40,000 celestial objects stored in the database. The mount is delivered with a stable stainless steel tripod which can be extended to a height of 140 cm.

Carrying capacity of the mount up to 15 kg

Menu language selectable - for example English

Electronic polar alignment aid for precise positioning

Autoguiding port for astrophotography

Further information about this mount can be found in the AVX presentation.


Celestron StarSense Autoguider
The Celestron StarSense Autoguider is an all-in-one solution that makes operating your telescope easier and more successful than ever before. This small, powerful device connects to your Celestron mount, increasing GoTo accuracy and helping you capture sharp, long-exposure astrophotographs with minimal effort. Whether you are just starting out in the hobby or have years of experience in astrophotography, this accessory will help you make the most of clear nights.

Further information on the StarSense can be found in the StarSense-Presentation.

Question:
How can I adapt my astro camera with 17.5 mm working distance?

Answer from Teleskop-Service:
Many cameras from ZWO, Atik, QHY ... have a working distance of 17.5 mm (distance T2 internal thread to sensor). The RASA8 works optimally if the sensor is 25 mm from the T2 thread connection.

We recommend the following adaptation (from RASA to camera):

T2AbstimmA2 ... 1.5 mm length

TST2V5 ... 5 mm length

T2AbstimmA1 ... 1 mm length

You will then be exactly at the correct distance. The adaptation also works with the Celestron # 93614 nebula filter for the astrograph.
