Below is a comparison between single dark frames taken with the Nikon D7500 and D5300 with exposure durations varying from 1 sec to 240 sec ( my usual main light frame exposure ) all at ISO400. Firstly a graph of the standard deviation of the noise in the dark frames versus exposure time: The standard deviation of the noise is a fairly constant 2 ADU less for the D7500 compared to the D5300 ( pretty much the difference in the read noise between the two ) However, the difference is not just in absolute terms but also in the quality of the noise ... Below are the dark fr

The Nikon D5300 has a well-earned reputation as one of the lowest noise DSLR cameras used for Astrophotography. Now that I have a new Nikon D7500, I was keen to see how it compared to the D5300 in terms of the level of read noise and the extent to which that read noise is non-random ( and thus needs to be removed using a Master Bias frame to prevent it summing up during image integration). So here goes ... ......... A single bias frame Nikon D5300: ISO400, 1/4000th second: This may look pretty bad but really the extreme stretch is bringing out the very small variat

The Discovery of the Sculptor Galaxy by Miss Caroline Herschel in 1783 On the 23rd of September 1783, sitting before her telescope in the field behind the house she shared with her brother William in Datchet near Slough in the south of England, Miss Caroline Herschel "swept" the sky searching for new comets and never before seen star clusters and nebulae. On this occasion, way down in the sky, not far above the Southern horizon, Miss Herschel saw and noted down a very bright and large nebula where one had never before been recorded and that was later recognised by her brother, Sir Willi

Posting in this forum after too long! One of the first attempts at taking photos of the moon. All photos taken using skywatcher 90mm refractor with eq2 mount, Nikon DSLR and 2x Barlow here and there. No exposure. Basic editing in cellphone. Thank you! Suggestions highly appreciated!

Newb here. I have settled on my first telescope being the 4SE or 6SE and I have a Sony Alpha 300 DSLR I would like to be able to connect to play around with AP. I am barely starting to grasp the terminology involved with telescopes in general but it seems connecting a camera to a telescope is a whole different ball game. It seems as though the 4SE has a separate eyepiece and camera attachment? Looks like you can just flip a knob to swap between the viewer and camera? Whereas the 6SE it appears that you have to remove the whole eyepiece to connect the camera. After reading some reviews eve

Hello everyone! I'm new here. So my question or questions may sound kinda ignorant. The answers may be a little obvious. I love this site and have read so many comments and learned so much! Anyway, I have a Canon 60D camera with live-view. I have a Tasco reflector with D=114mm F=900mm(this maybe a little small?). I will be using a T-ring/adapter and with this I hope to capture many decent photos. But for the eclipse, do need a special filter for the scope or the camera or both? If so, could you give suggestions where to get this? Thanks to everyone for any help!

Good Day to you all, I just wanted to share my first real attempt at photographing the Moon. This image is the result of a stack of 50 or so photos processed using Registax. I used my Nikon dslr and a telephoto lens. I would gladly welcome your critique. The image has been optimized for web, the original was over 60mb in size. Thank you Ben

I've been on the lookout for NLC's since the beginning of this season, but no luck, until last night. As I was getting ready for bed, I glanced out the window and FINALLY, some beautiful noctilucent clouds! Grabbed my DSLR and a tripod and ran outside. Camera: Sony SLT A77 Lens: Tamron SP 70-200 F/2.8 Di USD Tripod: Benro A4570T with Benro B1 ballhead Settings: manual mode, RAW, ISO 500, f/4.0, 0.5 sec, 120mm Post: Some basic minor tweaks in PSE15 (levels, contrast, unsharp mask and slight colour correction)

Hi all, I'm looking to buy a wide angle lens for my Canon 70d for photographing the night sky. I currently only have an 18-135mm lens. Having looked around, I'm finding it difficult to make the decision on my own! Does anyone have any recommendations? Max budget is around £300. Thanks!

Hi everyone, I’m putting a shopping list together for an astrophotography setup and I could really do with a bit of advice on my options thus far. My aim is to photograph DSO’s (I’m really keen on imaging galaxies) I need a rig that is easy to set up and also portable as I plan to transport it to the darkest skies I have available to me. I’ve been shooting wide field astrophotography with a DSLR and a tripod for about 5 years now so I already own a modified Sony A7S and an unmodified Canon 5D Mk3, so I will start by shooting with these bodies. I'm still undecided on scope a

So my last post about imaging the moon got alot of good feedback from you guys. But today after a down-pouring, overcast afternoon came a glorious clear evening with a beautiful red/purple sunset and an incredible Waxing Gibbous beaming onto the soaked pathways and grass in my garden. I set up my telescope on my little platform as usual along with my laptop, Neximage Burst camera and eyepieces. ( to align the Moon. ) I took 3 images of the Moon tonight. But out of the three my favorite was the image I took of the Copernicus crater. I know to a professional astrophotographer ( The majority

Good morning all I am still very much beginner. Bought some books, read a lot of articles, bought a cheap telescope to get familiar and now I would like to purchase something to make a new step. I want to get to know more about photography and observation and looking for a new scope. At the moment my favorite is this one: https://www.amazon.co.uk/Celestron-31051-Astromaster-Reflector-Telescope/dp/B0013Z42AK I would definitely want to have a motor and remote. Also, as critics are against the mount I am thinking about changing it with a different one if it proves to be that

Hi. I am new to astrophotography and want to start using an eyepiece camera with my Celestron eq130. Can anyone recommend a decent camera for a small budget, say £50. Also, do these type of cameras just fit into the telescope, or do they fit into a Barlow lens ??

Hi all! Long time since I've posted on the forums. Looks like an upgraded system. Nice I just wanted to share something that I think is extremely awesome! I didn't know exactly where to post this... I thought maybe in science, but it's also photography... I dunno. First of all... What is Schlieren Photography? From Wikipedia: "Schlieren photography is a visual process that is used to photograph the flow of fluids of varying density"... In this case -- Air. I watched this great tutorial on YouTube on how to make a homemade Schlieren setup, and it's pretty simple. Unlike
