Sequator stacking software4/16/2024 I was not using a field flattener, but the stellar images were perfect across the unvignetted field of view. As a result, the field was significantly vignetted but the two clusters were well covered. The telescope has a 3-inch focuser but, having a 2-inch barrel, could not be expected to cover the full frame sensor. The D610 was controlled over a USB cable from an Android tablet using the program qDslrDashboard and took 56, 20 second, exposures at an ISO of 800. The raw frames had been taken using a full frame Nikon D610 attached to a CFF Telescope’s 127 mm apochromat refractor employing an aspherical oil-spaced triplet objective. I currently do not have any wide angle data to try out, but decided to test Sequator with a set of Nikon raw files that I have extensively tried out with Deep Sky Stacker. As a result, the stars within the sky will be sharp as will be the foreground. The programs will then stack the sky area accounting for the movement of the stars across the sky but stack the foreground with no movement. The sky area is selected leaving the foreground unselected. In this case, a fixed tripod is used with exposures short enough to prevent star trailing. They both have the ability to treat the sky and any foreground separately – great for wide angle night landscapes. ![]() The former is only available for the Mac and the latter for Windows. More recently, two new stacking programs have become available Starry Landscape Stacker (~£38.99) and Sequator (free, but a contribution by paypal for a cup of coffee or two is suggested). The latest 64-bit version seems very stable. Astro Pixel Processor is a deep sky image processing software.For many years I have been using Deep Sky Stacker to align and stack my short exposure frames to give the result of a longer exposure. Photography, Astronomy, Image, and Astrophotography NINA is a night time imaging and astronomy software. APT stands for "AstroPhotography Tool" and it is like Swiss army knife for your astro imaging sessions. A powerful deep sky stacking application for astrophotography. Siril is an astronomical image processing tool, able to convert, pre-process images, help aligning. View more What are some alternatives? When comparing DeepSkyStacker and Sequator, you can also consider the following products By doing that, this will reduce the noise of the higher ISO and will help you edit your photos better. What you can also do, is take many pictures and stack them using a free software like Deep Sky Stacker or the simpler and also free sequator. ![]() Then you can do some math: if my tracker error is X arcseconds, and my camera pixel size is Y microns.I can use a lens of Z focal length and only have star trailing of W pixels. Https:///content/star-adventurer-review#:~:text=Performance,minute%20period%20of%20the%20worm. I recommend you test your star tracker mount to see how good/bad is the periodic error, etc. New astro-photographer looking for first telescope advice. There was a little editing afterwards, but nothing major, the stacking does most of the work. ![]() ![]() It's 30 x 15s exposures at 1600 ISO, all stacked in Sequator, which is free software that tracks stars and allows you to accurately stack images despite the stars moving. The Milky Way over the Knockmealdown mountains and Clogheen, as seen from the Galty Mountains Really sweet program for night photography. You can also add in dark images to remove camera noise. It will line up the images for you, and you can then do post processing in photoshop to improve whatever you need to to get the colors and images right. If you are a windows user, you can also use the program sequator (). Make sure to shoot when there isn't any moon light. Use something like stellarium to find something you want to photograph. You can stack images if you want a cleaner result. First attempt at astro | a7II + Tamron 17-28 f/2.8
