Okay, here goes... scope has been put away for too long, and finally got it out and am trying to learn how to get images. It seems I have an enormous amount to learn, but guess I have to crawl before I can fly. Last night was my first attempt to image Andromeda (seems like a popular first image... discovered that after last night's shoot). I am running Fedora Astronomy, and have the stacking software, am learning about dark frames, bias frames, etc. But, still crawling. This image was through an ES127 APO Triplet, on a NEQ6 Pro, Canon T3i with no modifications. Exposure was 1 minute at 12800 ISO, only tracking with what the mount provided. Exactly one exposure, processed in GIMP.

I also managed to get a pretty good shot of M33, considering I couldn't even see it in the finder...

First Photo, literally, just that one photo. Unguided, no processing, no flats. SBIG 11002, Finger Lakes Atlas Focuser, 300 sec.

Looks like a picture from the Deep Sky Wonders book published by Sky & Telescope from the Late Walter Scott Houston

First real attempt at imaging.  I don't count holding my cellphone up to the eyepiece as AP smile.gif

 

Skywatcher ProED 100

LX-85 Mount

D5300 unmodified

Bortle 6

 

3 nights of imaging, learning how to use a camera and what ISO means.

Stacked/aligned in DSS

Followed a video tutorial in Gimp for processing.  Adjusting color levels, removing noise, etc. 

 

Night 1: ISO 6400 30 second exposure

10 Dark

20 Flat

100 Light

This is the night I learned the importance of calibration frames.

 

Night 2: ISO 3200 2 minute exposure

37 Bias

6 Dark

20 Flat

49 Light

This is the night I learned the importance of proper polar alignment, and started shopping for a guidescope/camera.  Also the night that my camera hit the tripod for an undetermined amount of time and I lost a lot of my light frames because of it, in addition to a lot of stress on whether my mount was damaged.

 

Night 3: ISO 3200 1:15 exposure

37 Bias

4 Dark

20 Flat

36 Light

This is the night I only had a small window of opportunity to shoot, but was too excited not to try.

 

I know there's not supposed to be comments here but if you have any suggestions or tips/tricks to fix the galactic core (I feel like it's washed out and has a harsh line/transition to the rest of the image), I'd love to hear them.

Taken October 20th 2020 with a Celestron My First Scope (found at a thrift store for $5), a  hijacked 22mm lens (from my dad’s Vixen), and an iPhone 6s. Not horrible for a first attempt and an absolutely fabulous start to my 28th birthday! smile.gif

Ok so technically this is my third image,  the first one I was able to take after getting my telescope exchanged (the first one was out of alignment). Here is a photo of NGC 7000 The North American Nebula taken with a Williams Optics Redcat 51 and a Canon T3i. 2 hours of exposure time with 45 second shots.

This isn't quite my first astro image, but the first one I took with reasonably clear conditions. Picture taken on the 25th of October from near Leeds, UK. I used a 130mm Meade reflector and an adapted logitech webcam with a 2x barlow.

Since this sub forum is for DSO imagery, here is my very first ever attempt at Andromeda.

 

Camera/Sensor: Panasonic Lumix G9 (Micro Four Thirds)

Lens/Scope: Panasonic-Leica 50-200 f/2.8-4

Mount: none

 

Camera was on a ball head on top of a tripod. I would center the galaxy in the view, take a few images then re-center and repeat.

 

Lights: 300 * 2s @ 100mm, f/3.6, ISO 1000

Darks: 30

Bias: 30

Flats: 30

 

Stacked in SiriL and then processed in Luminar 4 (because I didn't know anything about PI, APP, etc)

 

First Andromeda Image
 
I just edited that same data again, this time in PI:
 
first M31 - PI edit

Although I can't compete with the the first images posted in this thread it is still fun to see the progress thorugh my photo library.

 

Here is my very first picture with a Canon 500d I bought on ebay for about 100 bucks and its stock lens:

First_Sky_Photo.jpeg

 

Just yesterday (about five months after the very first image) I took the following image (my gear changed since then):

masterLight_M45.jpeg

 

This is also the first light of my first astro camera ASI294MC Pro (still having trouble with the flats)

I live in a bortel 9 zone, so I think I don't have a lot of options from my backyard.

With this in mind, I decided to give something with a high magnitude a shot.

My first photo was M13, I took this with my Canon 800D and a 500mm telephoto lens:

 

attachicon.gifM13-4.jpg

 

 

And last week I went to a bortle 2 zone (Morvan region in France) to my in-laws, this is my first shot at M51.

This was with my Canon attached to my Celestron PowerSeeker 80EQ.

 

attachicon.gifM51-4.jpg

 

There is still a lot of learning, but I am pretty exited about how these first images turned out.

 

The hardest part for me is actually locating my targets before I can start shooting, especially in my backyard.

Any tips in making this easier? Especially when shooting from a bortle 9 zone?

I think I understand what the Bortle scale is (thanks to Wikipedia), but how did you find out what zones you and your in-laws live in? Please excuse my ignorance as, I am a beginner here.

There are a number of sites that will give you this info for a given location. One of my favorites is https://clearoutside.com

 

Put in the latitude and longitude of a location and it will give you the estimated sky quality as well as hourly viewing conditions for a week.

Got interested in astrophotography earlier this year; spent a little time reading up on it and decided to start somewhat small with a portable tracker (Fornax Lighttrack), a Canon T3i (unmodified as of now), and a Rokinon 135mm lens. Will probably work my way up to some fancier gear as long as I find myself enjoying the hobby through this portable setup.

Decided to try shooting Pleiades for my first astro project. I'm in the Denver metro area, so Bortle 6 or so at home but there are good Bortle 3 spots within like a 40 minute drive, so I tried shooting from there this past weekend which featured both clear skies and late moonrise around midnight. Ended up seeing like a half dozen to a dozen Taurid meteors over the course of the evening - unexpected benefit of doing it out at a dark site, I didn't even know they were going on.

 

Anyway, did 100 exposures, 30s each at ISO1600, plus Darks. Did flats and biases when I got back home. Got a trial version of PixInsight and tried to follow some tutorials from lightvortexastronomy.com on using some of the various tools to neutralize the background, tweak the histogram and curves, and reduce noise. Got this final image, which I'm pretty happy with for a first attempt:

So I'm not new to AP, but I am new to using a 4" APO refractor on an EQ6-R Pro mount.  Previously, I used a DSLR on a Star Adventurer or various stuff on a C8 with wedge and forks and most of it is fun to show friends and family but not very good.  New gear is So. Much. Better!  I consider July 2020 to be my rebirth as a new APer.

 

At any rate, I also discovered that the T-mount extensions rings I have from 1990 are just under 2" in diameter and fit perfectly inside the focusing tube of the APO.  That puts my DSLR sensor much closer to the objective lens and makes it that much easier to focus and get something in the FOV.  Guide scope arrived as well, and it took me a while to get rings for it and figure out a good mounting strategy.  The first night I took it all out, my laptop wasn't cooperating, so I just went with tracking from the mount.  Here are the results.

 

This is a mosaic of 9 images of the Pleiades that I took on 2020-11-06, 30 second exposures at ISO 800 and stitched together with Gimp.  I've never actually imaged this obvious target before (no idea why) and I intentionally tried to avoid any sign of nebulosity and just make it about the stars.

 

A couple frames had some camera shake before I remembered to turn on the self-timer (to avoid moving when I pressed the button).  I rotated it 90 degrees from "normal" to make it more aesthetically pleasing (at least, to me).

I've had a ton of fun unwrapping my old CPC1100 telescope and adding some of the new and accessible Zwo stuff to it. Yesterday I finally got a chance to take a first light shot with the camera. This is not stacked, just a single image.

Time to jump in and get my feet wet, as it were.

Bortle 8ish/7ish; shot with a D7200 and Rokinon 135mm lens; ISO 800, about 53 minutes total with ca. 30 sec subs stacked in DSS, tracking on a SkyGuider Pro.

Area around Sadr and Deneb in Cygnus.

My processing skills are pretty beginner level. removed a gradient emanating from the lower left corner with Gradient Xterminator, then finished(?) in Photoshop.

There's stuff there but the fine details seem to elude me.

Hello,

 

I'm new to this forum. This is my first post.

These are a few of my first shots.

 

The two DSO's are with an unmodded canon T2i, 75-300 zoom (not a high end one), and Star Adventurer tracker.

 

Nightsky
My first night sky shot.
My first properly processed and stacked series. No filters and plenty of light pollution. 
AndromedaBOOM
My first DSO. Only four photos stacked and processed using SiriL and GIMP

My first real deep sky image of M42. I thought polar alignment would be shaky since I used an AZ-GTi with an attached polar scope but 1min exposures look surprisingly quite alright. I wish I could do longer total exposure times but I have to shoot from a public space in a city so I can't walk away and have a coffee or something and it is getting cold around here.  
I did (some) dark, and bias frames, and some 'pseudo' flats after the fact and stacked in DSS and touching up and stretching in PS. 
Man, I started a couple of month ago inspired by too much time on my hands due to the pandemic. Got the AZ-GTi and the 102 Mak and took some images with my phone of Jupiter and Saturn. I was quite impressed what a small 250$ scope could do (my images were **** though)! Now I am getting sucked deeper and deeper into this....quite literally. Got the William Optics Z73 II for deep sky objects and I already ordered more stuff.... a light pollution filter, a guide scope, guide camera and an AsiAir Pro.... oh boy smile.gif

Hello. Nice to meet you all. I recently discovered my passion for astrophotography thanks to (AstroBackyard). And for my first astrophoto i took was the Cygnus constellation because the delta Cygnus was bright and i could focus. In the 30 stacks of 2,5 ...3 sec, exposure i found one photo that was odd. I was using my Lumix G3, f5,6--iso 2500 42mm. If it was just a small camera shake it should appear in the other's stars not just this one. Or did the stare just flared up. _1200406ccca.jpg

Not counting a few botched sessions, my first real attempt at astrophotography this past Friday.  Though seemingly well aligned, I could not get the mount to accurately track for more than 60 sec.  Still I am pleased with the result and my progress in learning Photoshop!  :-)

My first time having exposures over 2 minutes due to getting guiding to work.

and even though everything should be better (focus, guiding, processing) I thought I'd try imaging a nebula even though my camera is not modified for it.

 

This was 8 - 5 min exposures, heavily processed to get anything out of it.
