I captured two and a half additional nights of data on NGC 7822, this time with a different dual narrow-band filter that captures the Oxygen III emission line in the green and blue channels of the camera and the Sulphur II emission line on the red channel.

Combining this new data with the original data (Oxygen III and Hydrogen Alpha), I produced an SHO image where the Sulphur II, Hydrogen Alpha and Oxygen III emission lines are assigned to the the red, green and blue channels of the image respectively.

In total 13h 30m of data, 5h 5m on the Oiii+Ha filter and 8h 25m on the Oiii+Sii filter.

Here is a 3.3 x 2.2 degrees field of view in the constellation of Cepheus that includes many objects; the Lobster Claw Nebula (Sharpless 2-157), the Bubble Nebula (NGC 7635), the NGC 7538 emission nebula and the Sharpless 2-161 H II region, as well as the Messier 52 and NGC 7510 open clusters.

The data was captured under bright moonlight on three nights between August 27 and September 3. The moonlight made the data noisy and difficult to process.

Did you know there were sharks in space? 🦈

This is the Dark Shark Nebula, LDN 1235 from Lynds Dark Nebula catalogue, in the constellation of Cepheus. It is a large cloud of interstellar dust that reflects the light of surrounding stars.

I captured this image Tuesday night from La Mauricie National Park (QC, 🇨🇦) where the low light pollution (Bortle 3) allows capturing this very dim object in a reasonable amount of time.

There are 5 galaxies visible in the image, can you spot them? Two are easy, three are more difficult.

Look what I picked up this weekend! A complete set of the Webb Society's Deep-Sky Observer's Handbooks. The eight volume set covers double stars, nebulae, star clusters, galaxies, and variable stars. The books range in publication date from 1978 through to 1987. This, along with my Burnham's Celestial Handbooks are perfect for reading on cloudy nights and building observing lists for when it is clear.

I keep adding data to NGC7023 when there is an opportunity (no rain, no clouds, no smoke). 15 hours and 25 minutes so far.

Which color palette do you prefer? (refer to previous toots).

After over a month of cloudy nights, the sky finally opened up last Sunday night. I took this opportunity to get out and try a new filter I ordered in March and received early July - Astrophotography is definitely exercising ma patience.

These are the North America and Pelican nebulae (NGC 7000 & IC 5070) in the Cygnus constellation. The image uses the HOO palette where the Hydrogen emission line (Ha) is mapped to the red channel of the image and the Oxygen emission line (Oiii) is mapped to the green and blue channels.

The dark nebula LDN 935 is a gigantic interstellar dust cloud that separates the two emission nebulae by blocking the light they emit, giving this dark appearance.

Last night we went down to a local lake, and set up the #DwarfII while we retreated to the car to shelter from the mozzies.
This was just a trial run, but we got this rather nice shot of the Lagoon Nebula NGC6523.
Only 50*15s at gain80, and post processed in #snapseed .
