After a 20 year long hiatus - my last astrophoto was captured with a film camera in 1997 - at the beginning of 2020 I decided it was time to start again. So, January 25th 2020 I brought home my used Sky-Watcher NEQ6 Pro and I immediately started taking photos. Obviously, my first target was M42 in Orion. This was my first digital astrophotography. 31 subframes, 30s each, taken at ISO800 with my unmodified Nikon D90, Nikkor 70-300mm at 300mm f/6.3 - January 28th, 2020, home front yard, Bortle 5/6 sky, no guiding, no filters. A grand total of 15.5 minutes... A couple of week

Hi I've got an 8" dobsonian and I just got a dslr to connect to it. Obviously there's no tracking so what kind of things can I capture. Will I be able to do dso and planets? Thanks

The Witch Head Nebula, aka IC2118 & NGC1909 in the constellation Orion, near the star Rigel. This object is very large in the sky, being 3°×1°, so I had to use my smallest telescope to deliver the wide angle and low power needed to image all of the "Witches" profile. This is a very difficult object to image using a DSLR, and a dark sky is needed to capture it in it's full glory. I thought that I'd give it a go with my DSLR, and see what I end up with... I'm happy that the end result in my image shows the shape of the "Witch Head" but I think that the overall image will not be win© Mariusz Goralski

I managed to bag another object, this time the reflection Nebula M78 in the constellation Orion. I was planning to capture natural color subs than add some HAlpha and OIII narrowband data to emphesize the image details and reveal deeper matter, but after processing the OSC/RGB subs, I decided that adding the narrowband data is not necessary. This image was taken across two nights (juggling clouds), 6th and 11th February, and I managed to capture 3 hours and 18 minutes worth of useful subs (21x60 sec, 19x120 sec, 18x180 and 17 x 300 second subs). The telescope used was a 80mm ref© Mariusz Goralski

Hi, I just got a canon eos 600d to take pictures with my skywatcher 200p scope. I am using prime focus with it which seems to work fine despite the problems people face with getting it to focus. I plan to get some great shots of the moon, planets and orion nebula but I was wondering if theres a way I can get shots of dimmer objects in the sky. At the moment i am finding this hard as I am limited to a 1.5 second shutter speed in order to prevent star trails, I am putting the ISO up high to get the most light but I was wondering if there were better ways to go about getting the best pictures wit

From the album: Deep Sky Imaging
Mosaic of the Large Magellanic Cloud One of two (known) companion/satellite galaxies of the Milkyway galaxy, located 160,000LY away and only visible from the southern hemisphere. Due to the angular size of the LMC, this image consists of 4 frames, each exposed in natural color at 500mm focal length through an 80mm refractor. The 4 frame are combined into one image to fit the whole satellite galaxy into the frame. The camera used was my astromodded and active cooled canon 40D. Exposure time was 2 hours and 42 minutes per frame for a total of 11.5 hours for the whole image.© Mariusz Goralski

Hi All! I am currently in the market for getting a new telescope, as I have outgrown my current one (celestron 130eq). I own a DSLR camera already and have been experimenting with some astrophotography (first stage of getting addicted). Over the last few months I have now developed an urge to purchase a telescope that will allow me to take semi-decent deep space photos (Second stage of addition). The crux: I have a fairly limited budged, of around $ 1,000-$1,500 AUD, but I can't seem to find one that fits within the scope (pun not intended) of astrophotography. After doing some resear -
I would like to share my fourth image. With my "lucky week" of imaging, along with M33, I managed to finish also this project. This is my longest integration to date. These are IC 405 and IC 410, also known as the Flaming Star Nebula and the Tadpole Nebula, respectively, taken over 7 nights, under my Bortle 5/6 home sky. Total integration time: 18h 29m 00s. Here are the acquisition details: Mount: Sky-Watcher NEQ6 Pro Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series Camera: D5300 astromodified Reducer/flattener: Tecnosky 4 elements, 0.8x Guid- 12 replies

I would like to share my third image. I finally had a "lucky week", since my last session, December 18th. I managed 5 clear nights out of the past 6 (has to be a record, at least for me and my area) and I was able to finish a couple of projects I had started long ago and start a few new ones. This is M33, also known as the Triangulum Galaxy, taken over 10 nights, under my Bortle 5/6 home sky. Total integration time: 10h 14m 00s. Here are the acquisition details: Mount: Sky-Watcher NEQ6 Pro Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series Camera: D5300

Hi guys, hoping you can help with the tracking problems I'm coming across with my astrophotography setup. I've been using it since August 2020 and have kind of put up with the problem until last night where I think it's getting worse...

Hi, I'm just getting started with astrophotography and have been gathering the equipment. I've purchased the Star Watcher Evostar 72 APO Refractor Telescope and I've been researching all over the place for what flattener I should purchase. I'm wondering if there's a rule on how to pick one, does it have to be a certain size, brand, type, etc? Or does just any typical flattener work?... I see a wide range of prices and Its a little unclear to me what exactly I'm looking for since some flatteners look different than others. Im planning to connect this to a Nikon D7500 and I already have the M48 -

NGC 6357 is a nebula about 5500 light years away in the constellation Scorpius near the better known NGC 6334, AKA the "Cat's Paw" or "Bear Paw" nebula. This nebula was also given the name War and Peace Nebula because of its appearance in infrared images, the bright western part resembles a dove and the eastern part looks like a skull. This photo was taken through a 8" SCT at f6.3 (1280mm focal length) and exposed using a full spectrum modded and cooled Canon 40D DSLR.© Mariusz Goralski

Hello everyone, I'm looking to buy some NB filters and wanna make the best decision. 1. Does the size of the filter impacts the quality of the image? (is it a big impact?) 2. I know that lower HBW is best, but... for example: does the difference between 35nm and 7nm is worth the price? 3.Can you recommend some H-alpha, OIII, SII? Thank you in advance! Cheers, Vlad

I had a Hip replacement in 2016 and have not been 100% since so I have not setup my CEM60 Mount more than 2 times since then as it is ungainly to haul in and out of the house now compared to before the surgery. I miss my solar imaging and am strongly considering an iOptron Permanent Pier I have not found any videos on how to set it up though. I was also wondering what I should do about running wiring permanently as well or continue to haul it out every setup I do not and can not have an actual observatory so I run the wires from the livingroom laptop out a window (with a board the has 2 strips

Hi, I would like to share my design of a smart barn door tracker. It is a simple to build isosceles barn door tracker with tangent error correction through a Arduino micro-controller. I have shared all the details about the tracker including the mechanical design, electrical circuit and the software source code here: https://barndoor.spa...ference-design/ If you are interested in the math and other details about a barn door tracker, more details are there in the blog. Also find an online calculator which helps in calculating various parameters while designing a barn door tracker. The

Hello to all, I've just acquired my first tracking mount, a Skywatcher Star Adventurer, having dabbled with AP some years ago with a Celestron Nexstar 5SE which I still own but quickly realised back then that I needed an EQ mount. I captured my first ever planetary images this week with the 5SE and my new ZWO ASI290MC - Jupiter and Mars -which I was pleased with as a first stab but clearly need more work and knowledge. Looking forward to contributing more on the forums. Clear skies, Andy
