Mars will exceed 24-arc-sec in diameter between July 23rd and August 9th, 2018. This is 97 percent of the maximum of 25.13-arc-sec diameter attained during the last of the ‘favorable’ apparitions, which occurred in 2003.Association of Lunar and Planetary Observers
This year we received a phone call from Jeff Bennett with some questions about his new TV-NP127is scope. He’d only been using it since the fall of 2017 but was very enthusiastic and told us he’d tried other scopes, but the NP127is was the best he’d ever used. We viewed his astrobin.com page and we were impressed with his initial results. So, we asked him to tell us why he chose the NP127is for astro imaging and he told us in his own words.
Tele Vue President David Nagler recently received a “first-light” report from the very-first Tele Vue Bandmate Type 2 Nebustar filter owner. He purchased the filter at the Northeast Astronomy Forum (NEAF) this year where the filters were introduced. It turns out the gentleman has a long history with Tele Vue products, is a yearly attendee (like Tele Vue founder Al Nagler) at the Stellafane amateur telescope makers convention — and he even coined the moniker “Uncle Al” while at Stellafane.

At the end of this month, on July 27th, Mars will be in opposition and reach its greatest angular diameter — 24.3-arc-seconds — for the year. This is the best opposition since 2003. It’ll be greater than 21-arc-seconds tonight and well worth observing. For an explanation as to why some oppositions are better, what to expect from this year’s event, and accessories to better view and image Mars, see our blog post: Mars Opposition 2018 Preview.
