Nikon d70 is probably the easiest camera to full spectrumize. I used standard microscope slide glass to replace the hot mirror and its worked beautifully

Nice video! I use an ir-uv cut filter with my full spectrum camera for everyday use

Thanks for this. I was not happy to have invested in the polar scope and scratch my head for over a year wondering why following every video on it did not help me. I am 80% certain that this step is the trouble I was having.

great info! did you ever find out if the battery is rechargeable?

Thanks for this! I've struggled to get the alignment right, only to realise eventually that there was a loose Allen (hex) bolt on the underside of the William Optics wedge! Now that's tightened up, I still get a bit of "jitter" of the red circle when it zooms in, I was concerned by this but hadn't realised it was just due to atmospheric conditions. I was also unclear about setting and confirming positions 1 & 2, you've made that look straightforward. Just one pedantic point (sorry), the red dot / circle is not Polaris, that's the bright star about 0.5 degree away, it's the calculated celestial pole ("virtual pole").

Two talks about the discoverer of T Corona Borealis by an forgotton Irish astronomer called John Birmingham on May 12th 1866. He saw this saw this event with the naked eye and sent his observations to William Huggins of Tulse Hill observatory in the UK who made subsequent analyisis using an early form of a spectroscope. www.youtube.com/@Astronomy_West

Neighbor's light? Time to move to your dream location.

Hi, late comer to your channel. I'm a newbie to astrophotography. Do you have a plan, sketch, for your tripod. I have accessibility to a mechanical shop. Also, what would you do different to improve the tripod. Thanks for the videos.

I was looking for an explanation as to why I have no dot nor cross. This explained it very nicely and briefly. Thank you for your work.

Ioptron polar scope has better illumination and better eye relief and much easier to use . I have both Ioptron and skywatcher

Great explanation

Curious about the new GTIX? Is it something that you will report on?

About the zoom factor, it because you are using a FF lense on the DX non? If you have a crisp + DX lense… then it’s the same vs FX…no zoom?

Williams optics, as 2 model… high/low latitude… Is it true that they are the same and you only need to change a tooth?

Finally found a pure DSLR Astro photography… Will have questions:)

Great videos. They have helped me a ton. When I first installed the iPolar Scope it was working correctly. At some point during calibration, I must have screwed up because it is off by 90 degrees. To move the target up or down, I have to rotate the mount. To move it right or left, I raise or lower the mount. PA is PA, so I'm not worried, but it sure drives me nuts. How can I fix that? BTW,I upgraded to the Williams Optics base. WOW what a difference.

This wasn’t my first Aurora but it was my best so far. ❤

Great video George, Great information, I'm in South England, we could see it but where I am it was blown out, hopefully it will come soon so I can get out into a darker area.

What telescope do you use? I am a novice wanting to do this too! Where and how should I start? I know there are refractive and reflective telescopes....but what do you recommend for a beginner?

Seeing the aurora was something I’ll never forget!! Great video.

Here in Seattle, I was at ISO 800, f/3.2, and shutter between 1-2 seconds. At one point she was moving so fast I dropped to ½ sec and bumped the ISO to 1600. It was a crazy night on the Puget Sound!❤🎉

Very nice shots. I used setting very similar to yours and got great shots here in Michigan. But I made the mistake of using a nifty fifty. Too tight. Surprisingly, I set my wife's iPhone for night shots and they turned out even MORE amazing with the wade angle of that camera. glad you're back and looking forward to more content.

Great video skyguider pro ipolar added to my shopping list

Thanks for making this and helping me find it!

the comets hot blooded.😇✌

Nice! On this second night and last, in my bortle 9, skies. Canon 5D MK IV, time-lapse video mode. 6 second, iso 640, f3.5, TAMRON 15-30, at 15mm . Otherwise, the LP seemed to be a problem. Damn neighbors motion light. I was going to loosen the bulbs😅

This is beautiful! 😍

Nice video George ! I like it. So were those 500 images at 3-5 second long exposures each and then put into the time lapse ? I’m guessing I will have to increase my ISO with those shorter exposures. I was using ISO 800 last night and 15-20 second exposures for a single image. I’m shooting from Bortle 8.

Just to clarify. Walking noise happens when you stack images of a target that hasn't moved much between frames (PA and tracking/guiding are excellent). It occurs because tracking software confuses "not-so-random" noise with actual signal...so, noise is also stacked. The best way to cancel this out is by dithering...either automatically if you have a GOTO mount or manually by slightly nudging the mount a few pixels on any direction/axis every 2 or 3 light frames. Apart from this, great informative video

In this DSLR setup, why don't we connect the mount and the Asiair with the ST-4 port? Does Asiair app make a digital tracking of the stars? How does the tracking accuracy compare with the setup which a mount is counted to the Asiair?

Thank you for not deleting the trouble shooting scenes and clear instructions. 👏👏👏

Just waiting my the T3i body I picked up to return from getting the astro mod done to it. I am using my day use EOS RP now, besides the 1.6 aps-c crop for zoom any real optical differences I should be aware of doing astro with a cropped sensor?

Cool. Were some of the first. People so geeked about the solar eclipse.

Thank you so much. Hugs from Brazil.

how it wil start tracking. nobody mentioned this in tutorials

Hi sir . I read in the ipolar software read latitude and longitude from mount.. why you need to type al this numbers in the software . it you done it is daylight.

Thanks George

Great video. I just finished performing a full spectrum modification of my Canon T3 a few days ago. I had previously performed an Ha modification, but wasn't satisfied. I can't wait to test it, but the cloud monster just won't leave. I'm glad I found your channel. Please keep it up.👍🏾👍🏾👍🏾

I've had my gem28 for 2 years and last night was the first time it's come up with the confirm position. I think maybe a reset something on it and lost the previous positions. Helpful video. For some reason the instructions (which with hindsight are very clear) didn't make much sense to me in the freezing cold!

Thank you for this! :)

Thanks brother god bless

Thanks. We are driving to the eclipse. The thermometer is a great tip

This was great, George! Thanks so much. For those with GoTo on their star tracker (or mount) this is less than 1' away from IC4587 in case the star is not in their database. (I was following along with you on Stellarium and happened to see IC4587 nearby, so I thought I'd mention it.) Thanks again!

Thanks for the tips! I hope to image my first total eclipse in north Texas next month. I don't believe you mentioned it, but I am going to bracket heavily in order to (hopefully)) not miss a good exposure.

excellent ! thank you

I would have loved to shoot anything in March actually. Damn chem trails in the sky almost every other day. Have a nice AM5 mount and ASIAir now and have yet to use it for 3 weeks. Hope you get some clear skies as well up there in Utah.

An enthusiastic 2 thumbs up. You bypassed the usual suspects. Thanks for giving me and my new longer scope some "bait" fish, Whale , Haring 😊

Nice tutorial is really helpful for the upcoming Total Solar Eclipse in April! What type of filament did you print your parts with, I didn't hear if you ever mentioned it in the video?

Thank you for the video. Between the standard and the iPolar version, I'm deciding which one to go with. The content in your video is really helpful, particularly the portion showing the struggle and challenge encountered in alignment to the polar star.

That shelter is a game changer. And I’m just shy of 6’2 and was able to stand up in the middle with about an inch to spare. It was great.
