Imaging with a 300mm prime lens

Posted by dbock1 on June 18, 2021 at 5:20 PM

I've been using a 300mm f/4 prime lens that I'm borrowing for a bit, with my ZWO asi071mc pro camera.

Some interesting results

Comet C/2020 F3 (NEOWISE) - July 23, 2020

Posted by dbock1 on August 1, 2020 at 12:05 AM

While at the Boon Hill Observatory I setup to take images of Comet C/2020 F3 (NEOWISE)

Data taken on 7/23, 2020

Location: Boon Hill Observatory

Processed 7/26, 2020. First stack of 9 x 90 second frames (cropped)

Stacked on the core only so there are trailing stars.

No darks, so there is a lot of noise.

Canon T3i, 75mm @ f/4.5, ISO 1600, 90 second subs

Asteroid 162082 1998 HL1 on October 25 2019

Posted by dbock1 on October 29, 2019 at 9:40 AM

On October 25, 2019 I imaged asteroid 162082 1998 HL1 for about two hours.

This was through high cirrus clouds. I've made a video of the event.

Segment 1 is the Asteroid 162082 1998 HL1, segment 2 is the sky I was shooting through.

Segment one: 10" f/8 RC, ZWO asi071mc PRO camera cooled to -5C, 30 second frames at gain 500.

Segment two: Canon T3i w/10mm lens at f/5.6, 30 second frames at ISO 1600.

I managed to capture images of Comet C/2018 Y1 Iwamoto on February 18, February 22, and March 3, 2019. Those were the last clear nights we've had. You can review a few comet images at the flickr account. https://www.flickr.com/photos/141833769@N05/albums/72157705534756011
