Well done superb images ... brings back memories

I used to be into astrophotograpy but since getting married and family life getting in way sold most of my setup through lack of time.

I think I'm not going to be able to get into it till I retire in 30 years time.

By that time you won't be able to see stars for the amount of space junk and satellites! It's bad enough now lol
 
It seems the light pollution is less since the introduction of downward pointing street lamp.
I hope that aspect continues to improve

Yes I've had countless planes ... satellites and bits of iss and other things spoiling my 10 min exposures.

If your into ap then I guess they can be removed bu stacking....

Thanks very much! Yes it can be difficult balancing photography with family life. With how technology is progressing it's quite easy to get good images more quickly these days though.
 
The first Astrophotography Image at my new House, the California Nebula.

The Nebula is located in the Constellation Perseus. It's named after the outline of the Nebula resembling the US State of California.

A distance of 1,000 Light Years from Earth.

Hi guys,

Here's my latest image, the Rosette Nebula...


The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster, NGC 2244, (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.

The cluster and nebula lie at a distance of 5,000 light years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.


Imaged over two nights.

The Eastern Veil Nebula

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus, a supernova remnant and part of the Cygnus Loop. The source supernova was a star 20 times more massive than our Sun, which exploded between 10,000 and 20,000 years ago. NGC 6992 is around 2,400 light-years from Earth and is expanding at a velocity of about 1.5 million kilometers per hour.

Very good result for a single-shot colour cam, amazing how technology has advanced.

Also amazing how BIG the Veil neb is, I captured (almost) all of it with a large format CCD some years ago.
Best to click on the image and view on Flickr where you can zoom in - there's a lot of pixels :-)

That’s insanely good. And also a bit freaky as I was searching for this thread along with another a few days ago but couldn’t find this one for some reason.

Thanks very much. I had to search for the thread :D I haven't managed many Astro images this year thus far, clouds!

Yes it certainly is, I'll have a go at getting the whole lot one day, might have to do a mosaic unless I get a really widefield lens or refractor.
 
Excellent images. I picked up a used Edge 8 HD with starsense and a Altair 60 EDF S-FPL53 Refractor. I have never thought about astrophotography as I have always had v large dobs. I needed more portable scopes as my dob is impossible to lug about.
 
Hi, here's my latest Astro Photograph.

Imaged over three nights, this is my North American & Pelican Nebula image. The total exposure time is 8 hours and 12 minutes, consisting of 164 Lights. Calibrated with Darks (-10), Flats (from one night, along with dark flats). I omitted taking any after the first night, I did take flats after the second and third night's but I hadn't realised that I had ran out of disk space just as APT was taking flats on the morning after the third night - so I calibrated with just one set of flats from the second session, which seem to have worked alright.
