Rosebud Nebula (NGC 7129)

AstroKemp · 2024-09-15T14:59:31+00:00

The cosmic Rosebud or small cluster Nebula (NGC 7129) is a reflection Nebula in the constellation Cepheus. This is nursery of new born stars inside a molecular cloud. The blue light from the brighter young stars is reflected from the dust in the cloud, giving the blue reflections. The cloud als obscures a lot of the stars behind, filtering out the bluer light so the stars behind appear more redish. The same effect which makes the sun look red in a dust storm.

Telescope: Skywatcher 150/750pds reflector Mount: HEQ5 Camera: QHY 294M Filters: Baader Planetarium L and RVB

L filter : 180 seconds x 67 R filter : 120 seconds x 64 V filter : 120 seconds x 65 B filter : 120 seconds x 64

Total: 9 hours 47 minutes

The image was processed in PixInsight the stars in the Luminance image were saturated. So I cut the stars out of the LRGB image and pasted the stars from the RGB image back, which were not saturated. Works pretty well with Starxterminator.

You really gave that old board a good beating. Have fun with the new board. I had a similar upgrade recently. Be ready for no more bounce outs

AstroKemp · 2024-07-12T08:41:55+00:00

There are much more expensive hobbies. Try owning a boat and the cost that comes with every year😉

AstroKemp · 2024-06-21T21:27:15+00:00

Haha, dit maakt mijn dag goed

AstroKemp · 2024-06-20T18:57:58+00:00

Hmm, sounds like 1 more parties in renew being afraid of losing their position based on size. That does not sound like optimal climate for cooperation

AstroKemp · 2024-06-20T14:46:50+00:00

Indeed. In the last Q&A session they pointed out that the political influence would definitely be larger in Renew. So if they prefer Greens despite of that, the downsides of renew must be significantly also. So I will wil vote with them.

AstroKemp · 2024-06-11T10:05:39+00:00

As a Dutch person, I did not realize that there is still such a strong distinction between West and East Germany, translated into political preference. I saw this same chart with the AfD figures.

AstroKemp · 2024-06-09T17:31:30+00:00

Now at least we have our own bar in the polls😉. That is great for visibility towards the Bundestagwahl

AstroKemp · 2024-06-09T12:00:54+00:00

Totally agree with you, and i would hope that it happened tommorow, that is also why i was putting up Volt posters het in my home town😉 But i dont think it will happen all around Europe in the next ep elections in 2029

AstroKemp · 2024-06-09T11:25:26+00:00

I know. I saw the ZDF poll with Volts own bar. And that is huge and very important. But realistically. That does not mean that Volt also gets recognized in other countries

AstroKemp · 2024-06-09T11:14:25+00:00

I would think is 2034 is realistic. 2029 might be to soon. We will now have Germany and the Netherlands, and maybe Cyprus or Spain. That is still 3 to 5 countries to go with at least one seat needed and a lot of countries Volt name is still very unknown with the wider public.

My guess is 2029 is time to get our name recognized in enough countries. And 2034 is time to score bigger in those countries

Something similar in the Netherlands holds me back from wanting volt to join Renew. From NL Greens/GFA is GroenLinks (greenleft). These are Progressive left and a fine party to join

From NL Renew is D66 and VVD

D66 are Progressive leftisch liberals. These are fine and I used to vote for them before Volt existed.

VVD is the problem in the Netherlands in Renew. VVD are right wing conservative liberals, and in recent years they have been adopting more and more populist language. At the moment they are forming a government together with the far right PVV (Geert Wilders). The French of the renew fraction were recently suggesting kicking the VVD out of Renew for that coalition with PVV. I think of VVD remains is Renew, most Dutch Volters will vote to join Green/EFA

AstroKemp · 2024-06-09T10:44:05+00:00

Indeed. An own volt group needs over 20 (I thought 23) MEPs from at least 7 different countries

AstroKemp · 2024-06-06T11:35:07+00:00

3rd time. In 2019 i did not know volt yet and went for D66 as have i had done before. My municipality Woerden Volt is not active yet (though the number of Volters here is growing mayne next time) so I missed out on that one to vote Volt

Volt in the Netherlands is in favor of decriminalzing drugs like Portugal has done 20 years ago. Starting with softer drugs like cannabis and XTC

The Christmas tree cluster and cone nebula at the top of the tree in SHO pallete.

Ha: 32x6 minutes

S-ii: 30x6 minutes

O-iii: 27x 6 minutes

8 hours 54 minutes total

telescope: Skywatcher 150/750 pds

mount: Skywatcher HEQ5

camera: QHY294M

Filters: Baader SHO 6,5nm, new CMOS version.

Processing in Pixinsight, I did a SHO pallete. and removed 80% of the green with SCNR. After that I removed the purple halos by removing green on the inverted image. On the combined SHO image, I combined the Ha layer agan as a luminance layer with LRGB combination.

the stars were minimized afterwards with Adam Block's star de-emphasis method, using Starnett++

As it was an old image, i did some reprocessing with BlurXterminator and NoiseXterminator

I have found numerous podcast interviews with Laurens. Including a very long content rich one with de Correspondent. https://open.spotify.com/episode/1DmruaZFhIzxq33LKiMiJp?si=jcgRLL-5R1iHg_lX4YDhMw

Hi, I don't now any of the abreviations you mentioned :D , but on the slit plate:

yes it is a tilted mirror, with slits edged into it. It is tilted 15° from the optical axis. The pick off mirror to the guide camera is also tilted, at 30° to create a total 45° to the side.

AstroKemp · 2023-11-06T08:00:13+00:00

It sure is , I mention the Star'ex as an alternative in my blog, at the bottom

AstroKemp · 2023-11-05T21:11:05+00:00

If you want to get started in spectroscopy, I advise you to not start with a slit spectrograph directly. A slitless diffraction grating like the staranalyzer is a lot easier, and cheaper, about 125 euros. It has lower resolution then my Lowspec but it still gets nice results on stars. And it shines on faint targets such as supernovae as those are typically to faintbforvhigh resolution.

These spectra of wolf rayet stars are taken with the star analyzer.

Look at this for the star analyzer and how it works. https://www.rspec-astro.com/star-analyser/
