Sorry, I made a mistake on the price. It was $3600.00 (too early in the morning to be doing math in my head;))

That is what is great with narrow band imaging. You can get this same output in pretty light polluted skies!

Narrow band filters take out nearly all light pollution. There is a great astrophotographer that shoots near exclusively narrow band who lives on the outskirts of Denver, Colorado. He has images that will blow your mind, Hubble like. You can shoot with three narrow band filters and have the "Hubble Palatte", so you still have great color and even better "depth" to the image compared to visible wavelength imagery.

Here is his recent take on the Rosette Nebula, with three different looks, just taken with the three narrow band filters and a mono camera, Ha, OIII and SII.

Rosette - Narrow Band [C&C] - CCD/CMOS Astro Camera Imaging & Processing - Cloudy Nights

Here is a link to one of his images




So, as you can see, Astrophotography still works well in light polluted skies, with nebulas anyway. Galaxies would still work better in darker locations as you usually shoot those in LRGB + Ha.

Thanks everyone! Here is a photo of my imaging setup.


I have about $2600 tied up into it total, but once I learn how to use it, it should give me some pretty incredible images for many years.



For those of you who want to see the full size image of the Horsehead in Ha, click on the photo below. It will take to you Astrobin where the full size photo is uploaded.

I am getting deep into astrophotography. So deep, that I am even constructing an observatory. I have been shooting with a Pentax K1, but recently picked up a dedicated mono astro camera.

Took a quick imaging session last night.

Most of the winter targets are setting in the west early, so there is limited time for imaging them now before they hit the treeline.

This is just one hour (12, 5 minute exposures at 150 gain) using a narrow band Hydrogen Alpha filter. This filter REALLY brings out the dust detail in the Horsehead. I plan on imaging at least another hour tomorrow to build on this.

I shot this last night. Kinda spooky!

This is the Witches Head Nebula, a dim reflection nebula close to Rigel and the Orion Complex.

There are sure a lot of interesting objects in the night sky. You'd never know they were there if we didn't have long exposure photography.

I took this last night with my Stellarvue SV80 Access and Nikon D600. This is 31 frames at 300 seconds, 20 frames at 60 seconds and 30 frames at 30 seconds.

I am not real happy with it, but it is better than my last photo of Orion. Can't seem to get the colors just right and the trap isn't as defined as I'd like.

Thanks everyone! This is my best to-date. A lot has to do with the new guide setup. Since I can now guide my mount to sub-pixel accuracy, there is no muddling of the image from bad tracking.

I am having a huge amount of fun with astrophotography, it is a whole new way to use my cameras. Pretty addicting.

Here's a short GIF of Comet 45P from tonight. I was shooting between clouds, so it didn't turn out real well. This is 14, 3 minute frames with 3 minutes between each frame, so a total of 84 minutes.

That comet is moving pretty quick!

I think I am going to LOVE shooting with this scope.

This is 75, 1 minute exposures taken with the Stellarvue Access 80 and Pentax K1.

This is a work in progress. I still need to shoot lower exposures to get the Trapezium to show up. I'll be sure to post the final version here once I get it finished.

It is sooo much nicer to use a real scope compared to just a camera lens.

I received my new Stellarvue Access 80 ED yesterday. Luckily it was also a clear night! I set the scope up on my AZ-GTI in EQ mode and shot 1 minute subs. I probably could have went a little longer as the mount was tracking GREAT, I only had to reset it for the meridian flip.

So far, I am really liking the scope. I am using The Stellarvue SFF3-25-48 field flattener, but I still see pretty bad coma around the edges using a full frame DSLR. with a slight crop they are gone though.

Specs for the image are:

Scope: Stellarvue Acess 80 with 2.5" focuser, SFF3-25-48 field flattener
Focal Length: 560mm
Focal Ratio: F7
Camera: Pentax K-1
ISO: 1600
Exposure: 60 sec.
Shots: 100

I used Astro Pixel Processor for stacking. I am still learning the ropes with this program, so I am sure I am not doing things 100% correctly yet. I post processed in Photoshop and also in Nik Effects plugin.

Here is the photo.

I am using a Manfrotto Lens support since I am using a large 645 lens on the K-1.

I made a dovetail plate out of a piece of oak that I screwed to the Manfrotto lens support with a 1/4 x 20 bolt. You could use a vixen style dovetail plate but I didn't have one available.

Still Life Hammer Forged Copper Leaves

With winter fast approaching, I am starting to think of ways to make a little money during the winter months and to stay busy, since my normal business is kind of slow during these times.

I've bought some pure copper bar stock and I'm starting to make small trinkets. These seem to sell on places like Etsy pretty well. The steel pieces are nice, but I figured, I'd start trying to forge copper.

Forging copper is a little different than steel. I've already ruined a few parts by leaving them in the forge a little too long. I turn around and there is a melted puddle in the forge :hmm:

I am just a beginner at blacksmithing, but it is a fun new (to me) way of forming metal and creating something from raw materials. It also is a lot nicer standing in front of the forge now that it is getting cold out :lol:

Last night was the first clear night since I got my AZ-GTI, a tiny travel GOTO mount.

I still don't have my telescope yet, so I just used my Pentax K-1 and a A* 300mm F4 lens. After a quick and dirty polar alignment, I started imaging. I was able to get 50 second subs, which I am sure will improve when I polar align it correctly (it doesn't come with a polar scope) and take my time to star align it with more stars.

GOTO's were spot on.

I decided to image M33, the Triangulum Galaxy, and also Orion later.

Here is 50 images at 50 seconds each stacked, so a total of 41.6 minutes of imaging. This is a VERY zoomed in image, almost to 100%. I can't wait until my scope gets here!

And here is Orion, same setup as above, but with only 10 stacked frames. My camera battery died while imaging, I was hoping to get a lot more subs.

My EQG6-R Pro gets here tomorrow and I should have my Stellarvue 80mm Apo in next week. I won't be guiding just yet as business has been very slow lately and I need to save what I have for the rest of the winter. So, I'll be shooting unguided for a while. Atleast I should get good at polar aligning!

Tonight I got my Explore Scientific ED80 in. I also ordered the field flattener, but I didn't know it wasn't for DSLR's. I tried it out anyway tonight since I couldn't wait to modify my t ring for the right backfocus tomorrow.



It was very windy, and I am just using a lightweight tripod, so I was only able to take 11 photos and had to limit my exposures to 20 seconds each. I am using my Pentax K-1 with Astrotracer so I am not using a tracking mount.

Anyway, for the short amount of total exposure, and the incorrect backfocus on the field flattener, I can already see that the ED80 is going to be a huge improvement to my new hobby of astrophotography. So long old soviet lens ;)



Here's a quick edit from the session tonight,

This was shot from my backyard in Loveland, Colorado.

When the moon is not out, on a clear night I can very faintly see the Milky Way. When I shot this image, there was a near full moon and clouds just a little below the galaxy, so there was a considerable amount of skyglow.

Yup, I am GLAD I came back. The K-1 is such a great camera, and I can use some of my favorite lenses again. It was a shame that I couldn't use my Takumars with my Nikon, oh and the Soviet lenses. That old glass is seeing the light once more.

The new Astrotracer (new to me anyway ;)) is blowing me away. The K-1 has opened the world of astrophotography to me. Here's my 3rd attempt at using the Astrotracer feature with Andromeda. I am learning a huge amount and it is going to cost me money. This is 18 frames stacked, each frame is a 40 second exposure. Stacked in Astro Pixel Processor software and post processed in Photoshop. I used my old Soviet Tair 3 300mm lens for this shot.

Thanks everyone.



Well I ended up buying a new scope last night, an Explore Scientific ED80 triplet and its associated flattener.

I haven't bought an equatorial mount yet, my wallet has to recover . I think I should be able to get at least 30 second exposures with the built in Astrotracer feature on the K-1 though. That will have to do for now.



As a bonus, I plan on using the scope as a telephoto lens for wildlife. I've been meaning to get some longer glass, and this is the cheapest ~500mm f6 lens there is, with arguably better glass than any camera lens out there. I know it will be somewhat of a pain to focus, but I am used to manually focused lenses. The Tair 3 I used for this image is one of my prime wildlife lenses (even though I have more modern glass) since it is just SO good.

It also is mandatory to calibrate the compass right before you put the scope on the mount. I've found that if I start the calibration facing where I am going to be shooting, it seems to help a lot. Also, use mirror up mode and a remote control for the shutter. After pressing the remote once for the shutter to go up, wait 5 seconds before pressing the remote again. At these magnifications any slight shake will show up with out of round stars.

These images are highly cropped and the stars are still circular after 40 seconds. I could probably bump the time up even more.

Note, this is a fully edited image. These things are like shooting in RAW, the information is there, but it is up to you to pull it all out.

Just to give an example, here is a crop of the unedited TIFF I got from the stacking program. I used Photoshop as well as the Color Effects Pro plugin to pull all the detail out of the information.

It was taken with a Soviet Tair 3 300mm f4.5 lens. Half were shot at F5.6 and half at F8. 18 images in total taken at 1600 ISO and for 40 seconds each. I shot 5 dark frames while out there to make a bad pixel map and a master dark frame. I didn't use any flat frames on this shot.

I am using a trial version of Astro Pixel Processor, which is probably the easiest stacking program I've found so far. It is an expensive yearly investment, or a $150 EURO one time fee to buy,

Shot Andromeda again last night. With the near full moon, I didn't think it would turn out too good.

Here are 18 images stacked. Its a very tight crop, so it isn't super clear. I need to get a small telescope to get closer shots. Thinking of getting an ED80.
