NGC 6823 – 2018-08-08

NGC 6823

It appears that 17×6 minutes at ISO 1600 are barely a start for this nebulosity. I used my N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, aided by the IDAS LPS D2 filter. I acquired the lights from Dângău Mare, Cluj county. I personally, call this nebula by an indecent word, much like the sword of Orion. NGC 6820 is the little, yellowish nebula hiding in front of the larger, mainly red complex.

Messier 11 – Wild Duck Cluster

Messier 11, the Wild Duck Cluster

I imaged the Messier 11 Wild Duck Cluster, using the N 150/750, Baader MPCC Mark III, IDAS LPS D2, Canon 1100D mod, HEQ5 setup. I recorded 16×3 minutes of light at ISO 1600, on the night of 2018-08-07-08, from Dângău Mare, Cluj county.

Sharpless 112 – 2018-08-05

Sharpless 112

Using the good old setup, N 150/750, Baader MPCC Mark III, Canon 1100D mod with the IDAS LPS D2 filter, HEQ5, I took 15×4 minutes of the Sharpless 112 nebula in Cygnus. Would have taken more, had the Moon not risen. This nebula deserved more attention, it has a fairly high surface brightness, it’s not that small, being comparable to the Tulip nebula. But SH2-112’s neighborhood literally outshines it – just think about the North America Nebula, the Crescent Nebula, the Sadr Nebula, the Propeller, not to mention the Veil complex. I couldn’t even find a proper name for this object. I imaged from Dângău Mare, Cluj.

Saturn – 2018-08-03-04

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).

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
