    Randy H started the topic Dean's Stuff in the forum Classifieds 11 months, 1 week ago

    Attached is PDF of the slide show we reviewed at the Feb 2025 club meeting. It contains items from Dean Johnson’s equipment. Email, text, reply in forum, or call me if you may be interested in any of the items. I can then round up the items and bring them into the meeting to assess. Prices listed would be considered maximum and I’m sure Dean’s…[Read more]

    Randy H replied to the topic Meade DS2114ATS in the forum General Discussion 1 year, 2 months ago

    Hi Colin, If the telescope hasn’t been collimated (mirrors aligned), then doing that may vastly improve the image. We can take a look at it and perform the collimation for free if you wish. Let me know.
    Thanks,

    Randy H replied to the topic Working on A.I. Generated Night Sky Viewing Itinerary Generator project in the forum General Discussion 1 year, 3 months ago

    Very interesting John! I wonder if the search could customize a minimum horizon like 5 -10 degrees to refine usable targets.

    Randy H replied to the topic Orion website, telescope.com in the forum General Discussion 1 year, 5 months ago

    I think any of the <$20 options on Amazon are decent options. I’ve been ordering more of the rechargeable types. So far they seem to work OK.

    Randy H replied to the topic Orion website, telescope.com in the forum General Discussion 1 year, 5 months ago

    Hi Colin,

    You are correct. Orion’s website went dark July 31 and they along with Meade (who is another major astronomy equipment vendor being acquired by Orion) is gone too. Very unexpected and surprising since Orion has been perhaps the major supplier for amateur astronomers for decades.

    If you have money sent for your purchase, I would c…[Read more]

    Randy H replied to the topic 2022 Forestville/Mystery Cave Dark Sky Festival in the forum Outreach Programs 3 years, 5 months ago

    The event is still a “go”. I’ll be at Mystery Cave from 3-6. (I have an indoor presentation ready if cloudy).

    The evening event is on from 8-10:30 in the Forestville parking lot just before you get to the historic bridge. I’ll be over there around 7pm. Be sure to stop at the park office on the way in and say you’re a volunteer and they will give…[Read more]

    Randy H replied to the topic Observing tonight? in the forum General Discussion 3 years, 5 months ago

    See details of the Forestville Dark Sky Festival in the outreach folder on the forum. Looks like they plan on holding as many events as possible with or without clear skies. Saturday evening’s forecast for the deep sky viewing is looking better. The solar viewing forecast from 3-6 pm at the Mystery Cave site is still questionable.

    Randy H started the topic 2022 Forestville/Mystery Cave Dark Sky Festival in the forum Outreach Programs 3 years, 5 months ago

    The weather forecast for the Dark Sky Festival this weekend (August 20) is not looking favorable at this time. Nevertheless, here is the plan. We are scheduled for two times on Saturday. the first event is 3-6 pm at the Mystery Cave Visitor Center (Map 4 on attachment).

    The second event is the evening public sky viewing, and despite what is…[Read more]

    Randy H started the topic Oct 2, 2021 Frontenac State Park Outreach Event in the forum Outreach Programs 4 years, 4 months ago

    Just a note extending an invitation for club members who are available to help out with a pretty cool opportunity on the bluffs overlooking the Mississippi River at Frontenac State Park Saturday on the evening Oct 2nd. There is a backup rain date for this event Oct 9th, but I’m hoping we can do something more locally then.

    The event is being w…[Read more]
