Today I finally edited some data I've had for a while. It's a widefield shot (50mm prime lens) that was used on a modified Canon 600D. The end result is about 50 x 3 minute exposures, ISO 800 f/3.5. It was also shot with an IDAS D2 light pollution suppression filter riding atop an iOptron SkyGuider Pro. The Eastern skies when I shot this are full of street lights so there were some nasty gradients.
I also realised that the camera lens pulls itself in when the camera is switched off, which meant that even though I'd taped the focus ring down, my focus had changed and I couldn't use flat frames anymore, resulting in the horrible dust motes. Ah well, show must go on! Speaking of flat frames, I have a video on them on my YouTube channel and a post on my website.
I hope you enjoy the photo. It was actually quite difficult to process in a way that doesn't destroy any details in Andromeda. Also, because it wasn't dithered there's a lot of walking noise in the image that also ruined definition.
Just... appreciate it from afar, and don't zoom in! 😂
By stepping beyond
I've had 3 new mounts since after Xmas last year and it has been a real pita trying to get the first to mounts to operate correctly with my Sgp Software . March rolled in and I had lost too much time trying to get the 1st 2 mounts to do the job . I dipped back in the kitty and got an AVX straight out of the box took me to galaxies FAR FAR AWAY, WOOHOO! I've been trying to process the galaxy for a mount and match it with my archived data and finally I'm getting somewhere.
I've created my own darks library for my ASI1600mm Pro. Various gains and various exposure times all at -10 Celsius.
I'm just wondering what people do with them? Once you've taken darks and processed an image you get your master darks.
Do you guys just keep the master dark, in a master darks library, or do you process your darks again each time you stack a new image?
I'm just thinking to save storage, could I discard the dark sub frames and just keep the masters? I don't want to throw them away if that is wrong though.
Also, with this camera I take dark flats rather than bias frames. Because the scope is covered, do I need to do dark flats each time I take flats?
I have an even illuminated flat box which I always use at the same exposure lengths. I guess the only thing that could vary is the gain value.
I understand the need for flats every time you change focus, for each filter etc., but if I'm using the same exposure time can I just use a previous set of dark flats as long as the camera settings are the same?
If this is possible, can I then create a dark flats library for any difference in gain values? Not sure if I gain values affect dark flats though.
I've read that back, and that's a lot of questions! All help greatly received.
Since I am very new to this, I struggle a lot. Especially when observing planets and also recently deep sky objects. My telescope is an amateur telescope and its almost 11 years old (The telescope was re used a year ago). During summer of last year I took photos of Saturn,Jupiter and a month ago took photos of Venus and Mars. About 2 days ago I stumbled upon a new thing in the sky, (Unfortunately, I didn't take a picture). It definitely was in the Orion constellation as I had observed Betelgeuse and the 3 stars that were close to each other. After a couple of minutes later I saw 2 stars next to each other and another two which were on top of the other star, surrounding these set of stars were a blue-ish and grey-ish colour at the same time. I had done some research and many people told me it was the trapezium cluster found in Orion. I honestly don't know. Any ideas? Thanks.
