Here's another comet - Comet PanSTARRS C/2017 T2 , observed on the night of 2020 May 22 with a 115mm triplet refractor, AT115EDT: (1) At 34X in same FOV with galaxies M81 & M82 - at 73X (after ...

Comet Neowise was preceded by another comet, an observation of which I belatedly transcribed from voice recorder to Observations Spreadsheet - Comet Atlas C/2019 Y4 . I'll call this comet #32 . ...

Great job, Mario. You even got the ion tail almost hidden in the dust tail.

I found that it works very nicely for live stacking. Maybe a stand alone stacking program (like AS!-3) works "better", particularly for planetary imaging. But for ease of use it is hard to beat. I ...

That has been my thinking as well. I have been sharing with friends some of my many astro photos via an irregular Zoom meeting. These meetings have each focused on a particular category of astro ...

I have used SharpCap Pro for EAA ( Electronically Assisted Astronomy ) - which in my view is a nice compromise between visual and photographic observing. Here are a couple of results: Open Cluster ...

While my attempts at DSS stacking a series of comet images produced some OK results, I was not pleased with some artifacts around the coma of the comet. In contrast here is a single image post ...

The Raw images were from a camera on a simple barn-door tracker. I have a different set of Perseid meteor images taken on a fixed tripod, with no tracking. Some of these will be stacked with DSS. ...

When viewed at 100%, your image showed at least 2 galaxies: (1) M31 - the Andromeda Galaxy (2) M33 - the Triangulum Galaxy Below M31 is the open ...

I don't know why the variation. But that's what makes meteor observing so interesting My Geminid composite has mostly white trails. But that is with an 8 mm, f/2.8 fisheye lens of less than 3 mm ...
-
Thanks David for your contribution. I have recently made use of the comet-stack option in DSS. For that option to be available you must meet the following requirement : (1) Tell DSS where the comet ...
-
Leo (or anyone else) do you know of any links to predictions by meteor stream "dynamicists"? I've seen some predictions in the past of possible meteor storms, such as the Camelopardalids of 2014 ...
-
I see now what you were saying about star trails, Mike. I'll have to leave it to someone else to help with solving your problem, since I most always stack tracked images. I do have a set of ...

Here is my first composite from the night of 2020 August 11-12, the predicted maximum. This is what was captured with a film-era (1971) Mamiya-Sekor 55 mm f/1.4 lens. The background star field was ...
-
Mike, stacking will not get rid of star trails if such trails are present in the images you are stacking. Stacking will help smooth out the noise and reinforce signal (i.e. stars, star trails, ...
-
I have been working on assembling a composite image of meteors captured with my 55 mm f/1.4 film-era lens. I made an interesting discovery about DeepSkyStacker. It appears the flats must be at the ...
-
Hi Wade, It's good to hear from you. Sorry the weather for the Perseid shower wasn't optimum. But getting the NLC is a nice consolation. I've never seen or photographed that phenomenon. Maybe it ...
-
Thanks Leo for that informative article. As for your last paragraph above, I have noted the Geminids are just a white or have a bit of red coloration. The Orionids and Perseids have quite a few ...

Here is some information on that: https://leonid.arc.nasa.gov/meteor.html

Here are a couple of photos of our observing site for the 2020 Perseid meteor shower in the Oregon Coast Range Mountains, elevation 2600 ft. (790 meters). From this Bortle 2 site the major sources ...
