astronomical events august 2020 1

August 3 - Full Moon

This full Moon was known by some early Native American tribes as the Sturgeon Moon because the large sturgeon fish of the Great Lakes and other major lakes were more easily caught at this time of year. This Moon has also been known as the Green Corn Moon and the Grain Moon.

August 11, 12 - Perseids Meteor Shower

The Perseids meteor shower will produce up to 60 meteors per hour at its peak! Every year, the shower runs from July 17 to August 24. This year the meteor shower will peak on the night of the 11th into the early morning of the 12th. Find a dark location for the best viewing after midnight.

August 13 - Venus 

The planet Venus will reach greatest western elongation. This is the best time to view Venus because it will be at its highest point in the morning sky. Look for the bright planet in the eastern sky before sunrise. Check out our guide here to learn more on how to see planets with a telescope!

August 19 - New Moon

This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

Thanks OPT for the Astronomy events for August. I really appreciate it! Especially during this pandemic time, it’s been raining so much in Georgia that it prevents me from observing. But it’s good to read your updates on what’s in the sky for a particular month. Thanks again and keep up the great updates!

I understand the delay on my order 132612, (not happy) but I understand you have a military discount of which I was unaware. I am a 20 active service retiree and am I eligible for that discount? Seems reasonable considering the delay and the sights I am missing in the evening sky!

I also am not to happy about not getting at least a status about order number 131384. I understand the whole COVID-19 issue, especially where your are in California. Initially when I placed the order 10 days after the 1st order, the messages regarding the virus impact was 2-4 weeks. Now it’s 2-6 weeks and I only learned that today and no one sent me an email saying that. I’ve tried chat, email and phone communications with no success. Leaving PAID customers hanging after spending large amounts of “HOBBY” money when all they ask is to communicate those issues.
It will be very hard to place any additional purchases in the future with this non-customer care type attitude. My order, is also in my mind as being canceling very soon.

Hi Tony, thank you for bringing this to our attention. We are disappointed to learn that we failed to provide you with the upmost customer service. It was not our intention to mislead you with the product information. We are looking into this and working on making it right to prevent this situation from happening again.

I had hope to see some of the listed events, and it’s my fault I ordered so late on 27 June, but after emails and phone calls without any replies to neither, if I don’t get a reply by Friday 7 August of my order#133058, I’ll cancel. I am not happy of lack of communication regarding the order, and if you state your company has a “same day shipping guarantee” then either stick by it or state the reason for the delay. I called earlier today and just got an email reply, and have been informed that the Star Tracker Star Adventure I ordered will NOT be in supply until mid-August. What pain would it have been to have told that while ordering it by phone? I am happy they offered me a military discount, but what good is the order if it is backed up so far into the future? To say the least, I am not happy and I am afraid I will have to cancel the order. It should NOT have come to this, the client asking about an order, and of course, I should have been told about the delay and not-in-stock issue. It would have saved ME time and worry, and not put such a bad impression on you the company.
