I think this qualifies as the first image. It's a through the eye piece pic of the Moon prior to the January 2019 total lunar eclipse. The scope is an AWB OneSky 130. The camera is a removable lens module based on the Raspberry Pi camera module attached via a 3D printed cap of my own design. (There might have been some minor processing of the image but I don't think so.)

When I finally realized the RPi setup wasn't going to work the way I wanted it to, I picked up and SV105 and this is the first image after figuring out the SharpCap software configuration. Same scope, prime focus image.

Here are a couple I took last night. 30 second exposures with my Nikon DSLR and Sky-Watcher Alt Azimuth mount. Not the best but fun nonetheless 

 

one is M31 the other is Double Cluster....I hope

I have to say I'm stunned and amazed at the natural talent on display here.  So many people who knew exactly what to do from Day 1.  

 

My first 20 or so astrophotos were a bit rough.  But here we have people doing 3 to 5 minute exposures on their first pic and getting pinpoint stars.  They have excellent signal-to-noise ratio and the processing is immaculate!  Their flats are dead on, and there is no field rotation from imperfect polar alignment, incomplete subtraction of bad pixels, or focus drift. 

 

Some people are just naturals I guess.

I did an extensive amount of reading, here on CN and other websites about how to best go about DSO imaging. It was all trial and error. Some people have the experience coming from DSLR imaging, so they have a leg up on the others. I am 4 years into my imaging and I learn more everyday, as I keep reading and learning from mistakes and what others are doing. I have progressed from one camera to another, different techniques and through trial and error have increased my knowledge about imaging but do not consider myself a pro by any means. But it is fun nonetheless.

Messier 13 Hercules Globular Cluster. 110x10s frames for 18m 20s of total exposure. Shot using a Canon 5Ds at ISO 6400 attached to a Celestron EdgeHD 8" SCT scope on an Evolution mount. Processed using DeepSkyStacker and Photoshop CC.

 

Note that I cropped the image after processing in DSS in order to center and emphasize the cluster.

 

This is my first tracked and stacked astro photograph on a telescope. (I've done tripod AP photos using DSLRs and DSLR lenses before.)

When I bought the EdgeHD I wanted the Evo mount for viewing but I always intended to add an AVX mount. Until my budget allows me to add an AVX I'll just play with what I've got.

My first ever astro photo that I've processed from a couple of weeks ago. No idea what the green splodge is but I thought it was a pretty one of the milky way with the moon getting in the way....but I kinda like the effect it gave smile.gif

 

Using a Canon 1300D DSLR, standard tripod, 18-55mm lense and my Canon Connect app for a 25 second exposure at 18mm f/4.0 ISO 800.

First attempt at M31. This is a 60s exposure at ISO 1600.

 

I also tried stacking 200 ISO200 exposures without success. Over 3 hours the center of M31 drifted a fair amount. Guess I need to do better polar alignment? Currently not guiding. But I would think I should be able to get 60s exposures without guiding even with the CGEM.

 

Thanks for looking.

Too big lol.

12 inch sct. Bought everything used and trying to do what I can without dropping lots of money on gear.

At that focal length, you will need a good PA and guiding....

I don't have view of Polaris. I used the All Star Polar Alignment. I tried drift alignment but my horizon is blocked pretty much in all directions with tall trees.

ASPS computes my focal length at 3144mm. I have a focal reducer but need a shorter T adapter to achieve prime focus.

If guiding is my only option any recommendations for a budget off axis guider and camera?

Thanks!

Orion wide field from Sept 26. I'm happy to have caught the Flame nebula and a hazy bit of the Running Man.

 

Orion processed.png

 

Canon 40D unmodified

Canon 75-300mm @ 75mm f/6

barn door

 

54 x 30" lights ISO800

23 x 30" dark

80 x bias

no flats

 

Stacked in DeepSkyStacker; GIMP for basic processing: stretched, gradient removal, curve and black point clip. If I ever captured any faint H alpha emissions from Barnards Loop or near the Horsehead Nebula, I think I removed the data with my ham-fisted attempts to remove light pollution via the gradient removal.

 

September has been horribly cloudy and wet here on Vancouver Island. October shaping up the same way. Tough to get better when you only have 2 or three clear nights a month. At least I can reprocess images as I learn image processing.

 

Received a UHC clip-in filter on Monday, and have upgraded the stepper motor on the barn door tracker, will see how this affects acquisition next time there is a clear night. Forecast shows another 10 days to wait....

I took this picture yesterday with a new phone, I put an x3 zoom on my phone to remove the black around the eyepiece, I'm happy of the result but the telescope was shaking so much it was really hard to take a picture without it get blurry. I edited the picture with Registax 6 and Photoshop 2018.Moon.png

Last night I'd say I took my first real astro photo.. I still don't really know what I'm doing in terms of AP but here's what I came out with.

 

M57 JPEG.jpg

 

Now I really don't know the settings I used for this since I was just messing around with them until I got a decent enough image on my computer screen. I do know that I got only a little over an hour of data, and I was only able to do darks since I don't have a light box, and I couldn't leave my rig out all night to attempt sky light frames. So.. that's what my half finished photo turned out to be, though it's not a great photo, I was very happy with the results.

Here's my first unprocessed Ha 3-minute x 20 frames stacked. My first ever astrophotography session on my very first scope, Explore Scientific FD100 127 mm of the Elephant Trunk Nebula which I literally took less than an hour ago on my first clear night since I got scope.  Watched Chucks Astrophotography channel on youtube to learn how to do this and was very pleased my first stacked photo ever looks like this, even without darks, lights and flats. Can't wait to get all the photos stacked from O3 and SII along with the calibration frames. 

 

First Stacked HA (3 minutes x 20)

 

EQUIPMENT: ZWO 60mm Guide scope with a ZWO ASI224 Color Guide cam

                       Moonlight Focuser CFL,ZWO 7-position filterwheel with 36mm filters, 

                       ZWO ASI1600 PRO Cooled Monocrome Imaging Camera

                       Polemaster on a EQ6R-PRO mount. 

 

Software: 

Using SGP, PHD2 Guide software and PlateSolve2

 

Focus stats:

Focus is at 1.4 HFR average. 

 

PHD2 Stats:

Guiding is at .29 total average.

This is M27 taken with the following parameters

 

1. 11 X 120 sec exposures UNGUIDED

2. 1600 ISO on an unmodified Canon rebel XS

3. C11 2800 mm focal length

4. Focal reducer (f6.3)

5 10 Dark frames

 

I can pull more detail out by playing with the curves feature when processing the image. When I do this the image seems to suffer from vignetting. Any suggestions would be great. Especially any filter suggestions that I could use to reduce my exposure times and get rid of some of that brown red muddy color in the photos. I know there are tracking issues but I figure that 2 minutes unguided is not bad with that small amount of error. Not really ready to make the move to guiding as I dread all the extra accouterments that go along with this. I would really appreciate some useful suggestions that would allow me to use the equipment I already have. I know focus is not the best in this one but I was using backyard eos's focusing feature (FWHM)? Anyhow.. any comments or suggestions would be greatly appreciated. I will also include a jpeg of the processed image.

My first real (ie. not holding my phone up to the eyepiece) astrophoto.

 

Video recorded to MPEG4 using Altair Capture software for Linux (SERS not available)

Lights exported to PNG using ffmpeg.

Darks recorded and exported in the same way.

Stacked 176 lights (with 11 darks) in DeepSkyStacker. Apparently using zero iterations of the Auto Adaptive Weighted Average method (there's a bug running DSS under Wine in Linux).

Finally adjusted levels in GIMP.

M42. First attempt at stacking, fourth attempt at balancing levels

Then did it all again with different DSS options and level adjustments.
M42. Second attempt at stacking, second attempt at balancing levels
Oh, and no tracking :-)
