Solar Practice 1

I decided to do some solar imaging again. I briefly did some years ago but did not stick with it. This is my first solar image in over three years. I consider it a success since it is the sun and it is better than I ever did before.

Date: 6-13-20

Telescope: Coronado PST

Camera: ZWO ASI174 MM (uncooled)

Mount: Orion Sirius

Barlow: Orion Shorty 2x

Capture Software: Sharpcap

Frame: 500, best 50%

Processing: Autostakkert 2.6.8, PixInsight, Photoshop

I am glad I processed this as I almost did not because I thought it was way out of focus. The processing method was a combination of stuff I learned from Marty Wise (Wise Imaging) and Chuck Ayoub (Chuck's Astrophotography), thanks to both. I only did very simple things while processing and certainly need more practice. There was even a solar flare but I did not see it while I was capturing it. I brought it into the surface image even though it is not great.

So I got this image but sent back the ZWO174 Kit (it came with a filter wheel and filters) as I was not totally happy with it for a couple of reasons: 1) Must use a Barlow for focus, 2) Larger Pixel size - less resolution. I am exchanging it for an ASI178 which has a smaller pixel size - more resolution (but possibly more noise). Another advantage is I won't need a barlow for focusing so it is a better fit for the PST and it is cheaper. The next plan is turning my Orion ED80 that is collecting dust into a solar scope, I can use the savings from returning camera kit to get the bartender from Deep Space Nine!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
