Quote:To round out my lineup (see sig line, below), I have been thinking seriously about picking up a 4" Apo. They are readily available, portable, relatively light, cool down quickly, and have virtually no collimation issues. prices are within reach of most, new and used.Lotsa choices!If you expand the range of candidates to include the 90 to 110mm range, then the field of choices really explodes.But which one?I am a visual observer, and have both driven and undriven mounts.So, a poll: Which is the best one for the job?What is it about your choice that makes it stand out?Thanks!
Quote:I think we need to know your price point to make a real recommendation. Lots of difference between the price of a Takahashi on the high end and one of the new Lunts on the low......

Quote:Based on that, although hard to find, I agree with waso29, a used Tak FS102NSV would be what I would get. You get world class Tak fluorite quick cooling doublet optics in a compact package that accepts a binoviewer without optical correctors.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:I would love to have a LOMO 102/800. Too bad this Skylight/LOMO 102/800 is a one-off build; the LOMO OK4 triplet is another example of the very finest 4" objectives.A really pretty scope! Posted on the Vendor and Group Announcements forum back in July:Skylight/LOMO 102/800Rich
