Welcome to The Nightspirit Observatory located in Kyiv, Ukraine.
It's privat home observatory. I use this non-profit blog to document the natural beauty of our universe using modest equipment. I hope this site will be a source of inspiration for you to reach closer to the wonders of our universe.
The Nightspirit Observatory was founded by professional astronomer Sergii Pokhvala in Ukraine. The main field of stady of observatory is the high-speed spectroscopy and photometry of variable stars. Also, there is interest of observations of  comets, asteroids and meteors.
For observations of variable stars used the high-speed shooting technique. This enables to obtain results with high time resolution. High-speed observations shows fast effects of stars. For example, we can observed the fast processes such as spicules, prominences, flares, etc. Also this technique enables to use  "Lucky imaging" technique.
The observatory is located on the outskirts of Kyiv. It's not good place for astronomy because sky is very dirty. Dust, smog, pollutions created a parasitic illumination. Nevertheless, it's not problem for urban observations. Many objects are available!
Observatory has some excellent sky to the south and upward to the 60°.

The Nightspirit Observatory has cooperation with The Main Astronomical Observatory (MAO) of the National Academy of Sciences of Ukraine and Andrushivka Astronomical Observatory "East Eye". This enables to access to observations on the big telescopes. This is AZT-2 (70cm RC reflector) in MAO and Carl-Zeiss 600 (60cm RC reflector) in "East Eye". Every year I have observation campaign from April to November. This enables to obtain the work on the professional equipment and to take part in conferences and to print scientific articles.

1.  Maksutov Cassegrain Reflector

Intes Micro ALTER M 603 - 6"F/10


It is main telescope of The Nightspirit Observatory from March 2017!

It has Maksutov Cassegrain Reflector optical system. Telescope has very high quality.
This 6" Mak is a good telescope, has consistenly impressed every SCT user that looks through it. The optics are sharp, and are probably close to maximum performance that can be expected from an f/10 MCT.  The scope is well baffeled and very handy.
Mechanically the scope is solid and reasonably attractive; there is some backlash in the focuser but not extreme. I have noticed only a little image shift.

It's great instrument for spectroscopy, photometry and astrophoto of Deep Sky, Moon and bright planets. Usually, I use it for spectrometric and photometrical observations.

Also, It's great telescope for visual observations.

This telescope replaced the previous refractor Sky Watcher 2101.

2. Reflector by Maksutov


This telescope has Maksutov optical system, designed and created in USSR. Today this telescope can not used. It had first lite in 2013, but instrument need stabile mount. I hope that this excellent telescope will be used in 2016!

UPD: It was my main telescope from February 2016 till March 2017. Currently, This scope used like mobile device with manual EQ3 mount. Next step: motorization of EQ3 mount.

3. Refractor-triplet 



It has refractor optical system, three lenses in three groups. This is telephoto lens designed and created in USSR. It has excellent quality lens. Usually, I use it for guidescope or photography of Deep Sky and stellar fields. Also, it's great compact scope for trevelling. This is lens can be used for photometry and spectroscopy too. It's very universal and useful lens, nice assistant for Stargazers!

4. Sensors.

I use Canon 350D, Atik 314+L mono and QHY6 cameras for photometry, spectroscopy and astrophotography. Also, i have modified web camera Logitech 310 for guiding.

5. Accessories

- Star Analyser 200 (SA-200) diffraction grating
- Star Analyser 100 (SA-100) diffraction grating
- School experiments diffraction grating (R~300)
- H-Alpha filter
- U, B, V, R Johnson filters
- Blue, Green, Orange, Red, Dark (Solar) and Neutral Grey (Lunar) TAL 1.25" filter set
- Tair aperture filter set

- 32mm, 25mm, 10 mm oculars
- Antares 2inch 0.5x focal reducer 
- K-1 2x photo converter (Barlow lens) (USSR)

- Flip mirror
- Filter wheel 5-Position, 1.25"

EQDrive Standard the control unit, is intended for automation of work of the equatorial, German and azimuthal mounts.

The Nightspirit Observatory is open to any suggestions and collaborations! We need people for data processing which have skills in programming (MATLAB, Python or other).
Also, you can do financial assistance for the development of observatory :-) If you want give your help you can write message to e-mail: nightspirit10@gmail.com

Clear skies!

    So it happen? Can you talk something about it?

    1. Dear Roman!

      You can see some results of tesing of MTO-1000 in my two posts before:

      It was my main telescope from February 206 till March 2017.
      My main curent telescope is INTES ALTER M603.

      The information of news of Observatory will be updated in the near future.

      Best regards,

  2. «It has refractor optical system, three lenses in one group» [Tair-3]

    Excuse me, but it have 3 lenses in 3 groups!

  3. Sergii Pokhvala, do you have a Russian version of this your article?
    Also interested your professional graduation in field of astronomy, and, possible, science works, other articles .

    Сергей Похвала, у вас есть версия этой статьи на русском языке?
    Также интересует ваше профессиональное образование астронома и, возможно, научные работы, другие статьи.

  4. Roman, you mean "Short time-scale variability in the spectrum of O-B hot stars" article?
    Noup, only English...

    My astonomical education is Master degree of Astophysics in Taras Shevchenko University, Kyiv. Also, I finished Postgraduate studentship in Main Astronomical Observatory of NASU and now I'm working on my PhD dissertation.

    You can see my scientific publications here:

  5. Can you say what: H-Alpha filter, - U, V, R Johnson filters,
    where I can UT buy?

    Focal reducer is achromatic?

    1. Hello Roman!
      You can buy H-Alpha, H-beta (etc.) & Johnson filters in many astronomical shops, especially, in Europe. Before crisic in 2014 all this accessories were avaliable in Ukrainian www.astroshop.ua. I hope, many shops in CIS (СНГ) can deliver to order this accessories.
      I use filters which were manufactured of SE "Ukrmetrteststandart" many yeas ago.

      Focal reducer is achromatic, yes. You can find information of this reducer in internet.

  6. Thank you for article update. But info about sw 1201 refractor also was interesting.

    1. I hope, in future I will create review of this telescope.
      Also, you can find more info of SW 1201 on this page:
