Recently，the second solar chromosphere telescope jointly developed for Indian Institute of Astrophysics （IIAP）by Nanjing Institute of Astronomical optics & Technology （NIAOT）and Nanjing Astronomical Instruments Co.，LTD sees first light。

The solar chromosphere telescope self installed by india in Hanle observatory of （IIAP）consists of three tubes：

1）：chromosphere observing tube-- clear aperture 200mm

 full-disc observing mode：Φ41’（field of view）、1.21 arcsecond（spatial resolution）

 local observing mode：Φ16.5’（field of view）、0.48 arcsecond（spatial resolution）

          full-disc image and local image employ the same CCD

2）：photo-electric guiding telescope tube

3）：finding tube

The solar chromosphere telescope is equipped with Hα birefringence filter mounted in collimating optical system。

Speciafication of Hα birefringence filter：

1）：clear aperture 36 mm

2）：center wavelength（6562.81Å）、passband FWHM（0.4Å）

3）：wavelength shift range（+/-4Å ）controlled by PC with shift accuracy（1/100 Å）

4）：two-stage constant temperature function with accuracy of 1/1000C

The solar chromosphere telescope has automatic ponting、automatic tracking、CCD automatic finding function which is completely controlled by computer。

The solar chromosphere telescope can be remotely controlled while its parameter remotely modified so that remote observation can be achieved with corresponding attachments。

At present，NIAOT have developed two solar chromosphere telescope of its kind。on October 2014，the first one was installed in Kodaikanal observatory of IIAP by NIAOT and observation has been conducted since then。

The second one was self installed by india in Hanle observatory of （IIAP）under remote guidance of NIAOT。Diffraction limit images can be obtained by these two solar chromosphere telescope which are the best ones of its kind。
