Hey folks, I see several pictures from the HLA and they're beautiful, but I have a question. Why do people just snag data from the archive and process it? Isn't it a bit too far removed from the craft? You know, like setting up your gear, calibrating everything, framing the shot, taking exposures and all that, and then processing the data the next day. Isn't that what this is all about? Grabbing data off of the HLA seems like it wouldn't feel like astrophotography anymore. I've never tried. I don't mean to be rude, but I'm just curious about how people decided to do HLA processing only. And how fulfilling it may or may not be. For example, if I were to ever log-on to a remote site and click the mouse a few times and have data in the morning, even that would sort of feel like a let down. There's no substitute for being out under a clear dark sky in the thicket of it all! To let your eyes dark adapt as you scan the heavens while your rig loops through exposures to to be immersed in that calm chilly night air with nothing other than yourself and the Universe...where all worries and stress of your job and finances and relationships melt away and it's just peaceful calm beauty. You sort of let yourself go and become part of the night. Another shadow drifting under the cool glowing light from the early fall Milky Way. |

| I was just looking at the hubble data the other day ... weather has been terrible here last few weeks so no opportunity to capture anything. Otherwise largely agree with your sentiments. |

It's just a different way to enjoy astronomy. As a professional astronomer, I love to see more people digging into professional observatories' data archive, processing the images, and sharing the beautiful results with the public. This is a good way to bring astronomy to more people and is good for the society. From astrophotography hobbyists' point of view, not everyone can have frequent good weather, or easy access to dark places. Spending time on data that are publicly available is quite understandable. It's also a good exercise. |

I have to agree with you John. Carole |

| Processing professional data is another way to enjoy astrophotography, and the best way to see if that option suits you, is to have a try. You may be surprised from how hard that can be. |

Each to own I think. Also here is no dark sky in summer so if wish practice or do images either remote or archive. Sigga |

Have to run for a popcorn 🍿 Tricky question with no clear answer. For me using professional observatory data is a steal (sorry for offending my opponents). Unless you are a professional astronomer - keep your own works or your amateur colleagues (with their permission). But other points of view exist and it is great.  |

I mean, it's certainly rewarding to take raw data and turn it into something beautiful. For those who don't have the location, weather, time, and/or money required to gather one's own photons, I certainly don't begrudge them enjoying that aspect of astro-imaging. It just becomes a problem if you start thinking of Astrobin as a competition. Backyard astronomers don't want to be on the same playing field as Hubble. But I actually find those Hubble images useful as a reference to strive toward. |

Adel Kildeev: I think only taking something without permission is called "steal." The professional observatories open the archival images to the whole world. Everyone can download the images without permission as long as the images are found in the public domain. This is definitely not stealing. |

| Professional observatories equipment is no match to amateur telescopes, so comparing results make no sense. And professional observatories have specific purposes, scientific and very distant from just our amateur photos. Stealing (even with permission) scientific data for own pleasure, removing stars, changing colors etc- sorry, not my field. ;) |

You have forgotten all the algorithms and data reduction procedures we as amateurs steal from professional astronomers! Guilty as charged, your Honor! And for punishment, only eyepieces, pencils and drafting paper is allowed from now on! |

John, my main motivation for doing it is to polish my 'processiing' skills as a AP beginner. How close can i get from other published images? The other reason is the hla data provides something to do during cloudy season. Right now, i have not seen stars for the past 3 to 4 weeks. i agree with some of the posts, that it becomes a 'steal' when the image competes against 'earth' images for iotd. earth images taken with non professional equipment. The HLA data, in my opinion, is rather, easy to process. My astrobin index is disabled and i don't participate in the iotd, so i am not stealing the day. the astrobin iotd is another topic in itself, but i do not have any interest in it. clear skies |

Well...I saw just once a really dark sky when I was 14 years old...I enjoy too much outdoor AP, alive...my "great " gear, a gso 8 with color camera and IEQ45 gave me quite fair results...even at a Bortle 100 sky at my home....and the sky still really very crappy last year...and about this three last months also....so, between my work and my studies, I love to play with Hubble, Subaru, Kiso, Eso, Liverpool Telescope subs...and its great to play with awesome subs from other astrophotographer as well! We have lucky APs who could play with Chilescope, DSW, iTelescope...thats awesome subs also! I think whatever the source of your image subs (local, remote, Hubble, etc...) you have to show your passion at the final result...the observer could feel it! you have to express your soul and your emotions at these very moments (for example, when Im sad or depressed...I made some bad processing and then you show this bad result also! Or you wanna show it! )... thats feeling and true passion - you extracted blood from stone - which moves your will to produce a nice picture (or not, but you tried!) ....wherever your source came from...sure its only my opinion....  |
