Wise move?

Posted By Doug Walton
...you may find a scope with integrated tracking a LOT more convenient. Will you see more with 2" of extra aperture? Probably not, but that depends on the quality of the scope's mirrors and other factors. The GOTO is also fun and convenient.

Lunar crater Hainzel

Posted By Doug Walton
...how big (in diameter) those tiny craterlets are down in the larger crater. I'm just curious as to what kind of surface resolution we're seeing in this great image. Not to be too silly, but I keep expecting to see an image here someday where an Apollo lander can juuuust be identified visually. grin

Thanks...

Looking for a log book

Posted By Doug Walton
Dave, I usually just carry a small notepad in the field where I quickly write down sighting info, and then when I get home I just enter it into Birder's Diary.

Another Saturn from WSP

I like how the Crepe Ring has transparency over near the edge of the planet's edge. Wow.

Mine's perfect and give great views. Great coating job.

???? About Selling NEAF Items

Posted By Doug Walton
Jay Emirzian said:
...NEAF items sold at the Televue booth are considerably less then found here on Astromart. Al Nagler frowns upon reselling his NEAF seconds ... what is your feeling if someone is found selling an item right after the event at a considerably higher price?
I'm completely OK with it. Big deal if Al Nagler frowns on reselling his NEAF seconds. It's just equipment, and if buyer and seller come to agreement, then it's fine. I find it annoying when someone tries to sell something with "strings attached" - "you can only sell this if I approve it", or "you can only sell it at a certain price", or "you must sell it in a certain way".

All of this within the rules of Astromart, of course.

2" Barlowed Laser vs. 2" Laser/2" Autocollimator

Posted By Doug Walton
... about "if it ain't broke don't fix it". However, the question I'm asking is if a barlowed laser is AS ACCURATE or MORE ACCURATE as an autocollimator.

If a barlowed laser is absolutely as accurate or more accurate, then I might be able to save a step in my process and also do it a bit more easily at night.

However, if a barlowed laser is NOT as accurate as an autocollimator, I won't bother changing how I collimate.

Thanks...
