Saturn
From very bad to almost good seeing conditions, it was everything in just a few seconds. I used the N 150/750 on the HEQ5 with the ASI 224 MC camera.

Mars – 2018-08-03, first light
It is the first light of my new ASI 224MC camera. It is a much much much much much more comfortable world than the Scopium camera – although the latter has been battle tested, and it grew to my heart inspite of its limitations. 10000 frames, Gain=349 Exposure=0,01. I used the SW MC 102/1300 with a barlow, mounted on the HEQ5.

Lunar Eclipse 2018-07-27
Just before the Sun got lost
I imaged the lunar eclipse, as much as the clouds allowed me to. The main instrument was the Canon 1100D mod @ SW MC 102/1300 on the HEQ5. The secondary instrument was the battle tested veteran raspberry pi, and I used a Canon A800 too, and my phone.

Sunrise on the Moon
I recorded the Moon for three hours in order to capture the shadows get shorter, and mountains get into the light. The clouds were not my friend, so I kept four frames out of the 32 I recorded. I used the Skywatcher MC 102/1300 tube with the Scopium webcam, mounted on the HEQ5.

The IDAS LPS D2 filter
I tested the new filter (the DSLR clip in version) from within the city (many, too many Sodium and LED lights). I used the following:
Canon 1100D mod,
Canon EF 200mm f2.8L II USM,
HEQ5,
ExposureTime – 15 seconds
FNumber – 3.50
ISOSpeedRatings – 1600

NGC 6960 – Western Veil – 2018-07-14
NGC 6960, 12×4 min
This is the first light of the IDAS LPS D2 filter (the DSLR clip in version) I added to my toolkit. Using the Canon 1100D mod, I imaged 12×4 minutes at ISO 1600 with the N 150/750, Baader MPCC Mark III, HEQ5 setup, from Gyerőfidongó, Kolozs county.
Moon-Mars Conjunction – 2018-07-01
Moon, Mars
Old habits die hard, so I pointed a raspberry pi (an old friend of mine, a model B+ from a few years back, still functioning like a charm) plus some compatible camera with a large field of view (fish eye like) to record. Record what? IDK, just make timelapses and something *will* come out of it.
So I captured the conjunction of the Moon and Mars with a very modest and toy-like MacGyverish, but at the same time very versatile setup. The Raspberry Pi board is „floating” in a drainage tube with tight fittings, with a camera front from a cheap mock camera for weather protection and an ND filter in front (the Sun has a tendency to burn its trail into the sensor, already visible on every image). Since I risked to move the camera, the ND filter stays on for the night which kinda sucks… I know.
I also created a max combination of all the recorded images, function finalPixel(x,y) = max(pixel(frame[0], x,y), pixel(frame[1], x, y) … pixel(frame[n], x, y)) where max compared values of luminance = (rgb24 >> 16) + ((rgb24 >> 8) % 256)*2 + (rgb24 % 256).
Omega Centauri – 2016-05-02
Omega Centauri
While in Namibia, I imaged the largest globular cluster or galaxy remnant we have, the ω Centauri. I used a rather dark 300 mm photo lens, and my Canon 1100D mod on the HEQ5. I have taken 36×90 sec, ISO 1600 at f/7.1, according to the EXIF. I may still have some unprocessed raws hiding in some folders on the external hard drives :)

NGC 6791 – 2018-06-19-20
NGC 6791
I also captured an open cluster, 12x90sec, ISO 800.
NGC 6791 [open cluster in Lyr] 9.5m ø10′ [wiki] [simbad] 750mm, 800mm, 1000mm
It is not particularly interesting for visual/photographic viewing, I chose it because it is on my local zenith – and accessible in spite of the heavy light pollution. It is however a cluster that fell onto the sensor of Kepler during its first mission, and it is a very very old cluster. At 13000 light years, it is also very very far away for a visible open cluster.
Messier 39 – 2018-06-19-20
M39
During that same night, I imaged M39, 12x30sec ISO 800 frames. (tovább…)
