Take the guesswork out of using third-party heating bands or straps and increase your power efficiency with the Celestron Thermistor for Smart DewHeater Controllers. This accessory allows the Smart DewHeater Controller (sold separately) to deliver just the right amount warmth for to your telescope’s corrector to prevent dew without wasting battery. 6’ cable length accommodates a wide variety of configurations.

How it works

Connect the heating band to your telescope and place the Thermistor's sealed probe tip under the heating band. Plug each cable into its corresponding port of the Smart DewHeater Controller.

NOTE: This thermistor is not required if you are using a Celestron Dew Heater Ring because the ring already contains a built-in thermistor.

NOTE: Heating Band Not included.

Enhance your setup

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power your dew heater needs to keep the optics clear.

Specs

To achieve the best astroimages, it is important to attain the proper back-focus distance for your camera relative to the telescope it is being used with. If the back-focus distance your camera consumes is not exact, the performance at the corners of full frame imaging sensors will suffer—stars will appear elongated and not as pinpoints.
Example: RASA 8 with a ZWO ASI 183 MC PRO camera

• Required back-focus distance for RASA 8 with included M42 camera adapter: 25mm
• Back-focus consumed by ZWO ASI 183 MC PRO camera: 17.5mm
• To achieve equal back-focus distance, a 7.5mm M42 spacer ring is required

Celestron’s M42 Spacer Ring kit includes three different length spacer rings to achieve the proper back-focus distance with our popular Celestron optical tubes and T-thread camera adapters.

How to Use
Depending your method of astrophotography (DSLR or CCD/CMOS), there are two ways to use the M42 Spacer Ring. If you are using a DSLR, place the desired M42 Spacer Ring between your T-Ring and your T-Adapter for your optical tube. If you are using a CCD or CMOS camera, place the desired M42 Spacer Ring between the camera and the T-Adapter for your optical tube.

Below is a quick guide to help you determine which spacer ring to use for our EdgeHD, Schmidt-Cassegrain, and RASA 8 optical tubes:

45.1fps (10bit, high speed mode). ST4 Port: Can be used to connect with the auto guide port of mount
for guiding

.

Readout Noise Readout noise includes pixel noise, circuit noise, and ADC quantization noise. The lower the readout noise, the better. As can be seen, the readout noise of ASI715MC is very low. As the gain value goes high, the readout noise goes down.

Quantum Efficiency The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout
noise are necessary to improve the image signal-to-noise ratio. According to our estimation, the QE peak value of ASI715MC is about80%.

Upgraded from SkyTracker, the new Pro version is more compact, small enough to fit on your palm, better precision, silent tracking, it even has a built-in rechargeable power source that runs for up to 24 hours of continuous operation. With built-in iPolar, quick and accurate polar alignment is just a joy.

The SkyTracker Pro features four tracking rates, 1X or sidereal, 1/2X for sky and landscape, solar and lunar. All 4 tracking rates work in both northern and southern hemispheres. We have also added a quick slew mode with both forward and reverse to help quickly reframing your image without disrupting the cameras position.

We have made big improvements on the SkyTracker Pro’s removable alt-azimuth base, which features a precision bubble level, degree markings for the altitude and a built in post for the azimuth control. You can also mount the SkyTracker Pro head (without the base) directly to any standard photographic tripod with 1/4” or 3/8” threads. The SkyTracker Pro is certainly a must have tool for any photographer interested in astroscape or wide field astrophotography.
