M81 and Holmberg IX

M81 is also known as The Bode's Galaxy. It's located in the constellation Ursa Major and its distance is 12 million light years. It's brobably one of the most beautiful galaxies in the northern hemisphere.

This image has exposure L 310m and RGB 60m each channel. This image was taken with VC200L @F/6, QSI583wsg and Takahashi EM-200Temma2Jr. Guiding was done with Lodestar and QSI inbuild OAG. Big image is here.

California Nebula in Ha

This was a side product of M42 imaging sessions. Before M42 was high enough (max. 23 degrees here), I spent some time with NGC 1499 (The California Nebula). This image consists of 12 x 20m exposures with QSI 583wsg and FSQ-85EDX.

California Nebula is located in the constellation Perseus. Its shape resembles the state of California.

M42 in Hubble palette - QSI583wsg first light

This is the first-light image of QSI583wsg CCD. The camera has the popular KAF8300 chip. It's a beautifully engineered piece of equipment.

M42 The Great Nebula of Orion is perhaps one of the most stunning celestial objects visible from my latitudes and worth the CCD first light. Exposure SII 11x20m, Ha 13x20m and OIII 9x20m with FSQ85EDX, QSI583wsg, Baader narrow band filters and Takahashi EM-200Temma2Jr. This is a bit challenging target in my northern latitudes, it never rises more than 25 degrees above the horizon. Also the dynamic range of the M42 brightness gives challenges for both the camera and image processing.

NGC891

NGC 891 is an edge-on galaxy in the constellation Andromeda. It's about 30 million light years from Earth. It was discovered by William Herchel 1784. This image has exposure of 8h 30m with VC200L @F/9, QHY8, SXV-AO and IDAS LPS. The image below is a crop of 66% downsampled original.

NGC7000 finalized in HST palette

After 8 nights imaging and 1 day processing the results, this is now finalized. Exposure time is 15 hours per each two images in the mosaic. Taken with FSQ-85EDX, QHY8, Baader narrowband filters and Takahashi EM-200Temma2Jr mount. Image processing follows the ideas presented in Tone Mapping by J-P Metsävainio. Full size original (6MB) is here.



This is a crop from the best signal region. Big one is here.

NGC 6946 in RGB

NGC 6946 is also known as The Fireworks Galaxy. It is in the constellation Cepheus and the distance to it is 10 million light years. It is one of our neighbor galaxies. This image has exposure of 9 hours with VC200L @F/9, QHY8, SXV-AO and IDAS LPS. A particular attention was paid to preserve star colors. This guideline by Russel Croman was applied. Original image with almost the whole FOV is here.

The Iris Nebula

NGC7023 The Iris Nebula is a reflection nebula in the constellation Cepheus. The nebula core is relatively bright with magnitude +7 star. However, the outer rims are faint and require long exposures. The distance to the nebula is about 1300 light years and it is six light years across. This image has exposure of 8 hours and it is made with VC200L, QHY8, SXV-AO, IDAS LPS and EM-200Temma2Jr. 50% down sampled image is here.
