WANTED: Baader solar filter film
I've got a Meade ETX-125, and, 11x80 and 10x50 binoculars all needing solar filters for the upcoming eclipse. Anyone have a supply of Baader film you're willing to sell for this project? And, if not, any recommendations for bulk suppliers of the material?

Re: The largest optical telescope that will ever be built?
Just finished watching the video. Your phrase "...covers some basics about big telescopes.." makes me smile. There are absolutely no 'basics' involved here. Simply stunning when you consider it's 430+ tons of metal and glass requiring nanometers worth of precision both mechanically and opt...

Webb and JuMBO discovery
Amazing -- seems the universe still has a few surprises up its celestial sleeve.

Re: Astrocalendar 2024 (Guy Ottewell)
I have a 2023 copy, and while parts of it are similar to his original artwork, some - like the monthly star charts - are disappointing. Quality of the paper isn't up to par as far as I recall the originals. The smaller format is more convenient, but the details his charts and diagrams suffer from th...

Re: Cataracts
Thanks to everyone who chimed in on this topic. Had my pre-op evaluation today, first surgery on the 26th. Opted for intermediate distance monofocal IOL as a compromise between the vision extremes of my hobby interests (i.e., astronomy vs. fly fishing). Talked with my doc about the potential for a w...

Re: Cataracts
This past week I learned that my fuzzy right-eye vision is due to a new cataract. I intend to have the surgery in the next couple of months, but I'd like to learn from others with this experience. Specifically, I need to decide if I should have my new lens provide distance vision, or near vision. I...

Re: Farewell to Ottewell's Astronomical Calendar
His website noted that the old hard copies were printed in two color, but the PDFs for 2022 and 2023 are four color. What is used for the 2023 hard copy? Just got my copy, and it's full color. I'm nostalgic for the original 'large' format, and I'm not a fan of the cheap paper used in the new editio...

Re: Bill Volna article
A visit to Bill's shop many years ago was simply mind-blowing. What an amazing collection of equipment, gear, parts, tools, etc. My favorite memory of Bill was a night at Metcalf when he brought the Tardis out. The evening was chilly, but the interior of the Tardis was toasty. Bill had a tendency to...

Re: Saturn's Large Moon Titan Will Occult an 8th Magnitude Star July 9th
My experience with the 1989 event is detailed in the October 89 issue of Gemini. I've long since lost the raw data I collected from the event, but a summary of the results and a description of the process I used are included in the article. I still have a Radio Shack TRS-80 Model 102 computer (not t...

I set an alarm for 2am figuring I would head to ELO if weather looked promising, but Bloomington skies were totally overcast, so back to bed for me.

I'm glad I'm not the only one that thinks this is weird. I've long wanted to get rid of Daylight Saving Time because it was an arbitrary hassle that saved nothing. Getting rid of Standard Time doesn't make any sense to me. High noon will forever be at 1pm. <sigh> Hopefully they'll include funding t...

Re: Sunshine Protection Act
Standard time should be just that -- THE standard time for the US. Particularly important for northern tier states, where nights are longer and sunrises later. Adding an extra hour of darkness creates a number of problems / risks when applying DST year round. And there is substantial scientific evid...

I'd followed an out-of-date bookmark just prior to getting this error, accessing what appeared to be an old version of the site at http://forums.mnastro.org/. Perhaps that accounts for the problem?

Not a forum issue, but when I access the main site (www.mnastro.org) I'm rejected by Wordfence with the following error message:

Re: Possible Spotting of Dragon Spacecraft Saturday August 1st if the Undocking Occurs as Scheduled
Enjoyed watching the pass of ISS and Dragon in formation. Saw the ISS first totally by accident and then noticed Dragon tracking just ahead of it.
Oh and no binoculars needed to see Dragon!
