Hello together, I tried capturing the milky way a few says ago. This isn't my first time doing astrophotography but I ran into a problem. I captured 128 light frames, 51 darks and +100 flat and bias frames. I loaded them into DSS and registered them. Firstly I set the threshold so that ~200 stars were found. All pictures have a very similar score (1070-1400) and number of stars (180-220). There were no clouds. After the first stack the result looked horrible. I looked at the offset data and some images got rotated by over 150 degrees which can't be since all pictures were taken within an hour. Some pictures did't have any offset information at all (NC)! I changed the star detection threshold and tried everything from 15 to 500 stars with the same result. I looked a bit closer which stars got detected and this seems kind of random. The stars that got recognized are not even similar in 2 pictures taken after each other. What else can I try? I used the Sony A7iii with the Samyang (Rokinon) 14mm f/2.8. It was my first night with the 14mm. I stacked a set of images of the Pleiades a few weeks ago with no problems at all (Sony a7iii, Tamron 70-180mm f/2.8). Converting the raw images into DNG didn't fix the issue. Thanks! DSC02847.tif

Hello, I am new to this forum and would like to get some information regarding astrophotography. I have a Nikon D3200 with 2 lenses (55-200mm and 18-55m). The lenses came bundled with the camera, so I'm guessing they are very beginner-level (which has been OK so far) Here are my questions (with apologies if they do not make sense): 1) Are these lenses sufficient for astrophotography or do I need to get a better lens? 2) If I need to get a better lens, what should I get: a zoom lens or a fixed lens? 3) If I am going to take pictures of the Milky Way or of planets and stars, do I need an equatorial mount? If not, how can I counteract the east-west motion of the earth during long exposures? Regards

From the album: Deep Sky Imaging
This image of a part of the Milky Way/Sagittarius region was imaged with a QHY268M and a Sigma 80-400mm EX zoom telephoto lens at 80mm focal length on the nights between 25th June and the morning of 9th July 2022. Sagittarius is a large constellation located south of the ecliptic, FOV near toward the center of the Milky Way galaxy. This constellation is in a region of the Milky Way which is rich in gas and dust as well as various nebulae and objects through out. Objects such as the Omega, Trifid and Lagoon nebulae... full list of objects detected in Astrometry.net listed below. The total integration time for this image was 14 hours and 52 minutes of subs, 54 subs each of 90 and 180 second for Luminance, and 100 x 60 second subs for the red channel, 71 x 120 second subs for the green channel and 64 x 180 second subs for the blue channel for the broadband data and 43 x 300 second H-Alpha subs to emphasize the Hydrogen Alpha signal in the frame.

Last night and tonight I have been out with binoculars shortly after 11pm, the sun finally seems to be low enough not to wash out the milky way, helped by some cloud banks in just the right places, too. I was able to see the main bands of the milky way with the naked eye from my door step, though there are security lights so hiding around the corner of the garage or somewhere in the garden is best to avoid setting them off. I fancied tonight that I could just make out the faint fuzzy patch that is the Andromeda galaxy, sure enough a quick glance with binoculars confirmed this, still got it! Very pleased to be seeing the stars again, the summer has seen quite a few clear nights so far but it's been so light and hot I just couldn't bring myself to get out there, just to see a few of the brightest stars. I am considering purchasing a C6 to enable me to get the most out of my CG-4 mount, it's good with the 150P but I suspect any larger a reflector would unbalance it, a compact C6 will be close to the weight limit but at least it will be small so very easy to handle. I find the NEQ6 a daunting thought, my back aches just thinking about getting that thing out.

From the album: Imaging Challenge #15 - The Milky Way - Now Closed
A 25 second exposure from a time-lapse taken over the cloud filled Caldera de Taburiente in La Palma in the Canary Islands. Mars is the red object to the left of the Milky Way. Saturn is in there too but is lost amongst the milky way. The bright lights hidden under the clouds are from the towns of Los Llanos and Tazacorte only about 7-8 miles away as the crow flies but about 90 minutes away by car! 25 sec at f/1.8, 14mm Sigma lens, ISO 3200, Canon 6D. The scene was illuminated by a crescent moon beyond the right of the image.© James Mackay

From the album: Deep Sky Imaging
This was imaged using a astro modded Canon 40D through a 50mm prime lens for the wide coverage, piggy backed on my SCT, so tracked and guided using my 80mm frac as a guide scope. Total Exposure was 2 hours, consisting of 30 x 120s, 15 x 60s and 30 x 30s subs at ISO800 With in we can see part of the stars making up the Scorpius constellation, Milky way, Rho Ophiuchus, Antares, M80 and M4 among the gas, dust and nebulosity.© Mariusz Goralski

A late night Milky Way shot from Woodlands Campsite in Devon. The picture is aimed west - the nearest LP is Plymouth about 20-25 miles away. The Summer triangle is the area above the trees - the field of view is very wide and goes up and slightly beyond the zenith. Taken through a Canon 6D, 14mm Samyang lens at f/4. 1x 30 second exposure at ISO6400.© James Mackay

From the album: La Palma
A crescent moon setting over La Palma from the north facing side of the Roque de Los Muchachos. The astronomers accommodation is visible to the far right of the picture and clouds down near sea level (about 6000ft lower) reflect the moonlight. The Milky Way is coming into view on the left of the picture. A single picture can't give you sound (yet) but at this spot the sound of the cicada's was almost deafening unlike a few hundred yards the other way in the caldera whee the sound of the mosquitos is almost deafening... 20 seconds through a Canon 6D, 14mm Samyang lens at f/2.8, ISO1600© James Mackay
