I have some images of C/2022 E3 (ZTF) taken with iTelescopes T14 & T19 on 2023 Jan 27. These are .fits images ~40MB each. How can I compress them to fit on the Forum? I tried using Astro Pixel Processor to convert the images to .jpg format but the image is dark. The stretched image looks terrible.

They're uploaded below.

I was doing some testing with the newly available iTelescope T19, and got a deep image of C/2017 K2 (PANSTARRS). I thought I'd share it here. This is a stack of 3x10-minute images in the Lum filter.

Comet 156P is brightening rapidly and unexpectedly, and is currently magnitude 11.8 (or brighter). It may be fun to keep an eye on it in the coming days. I have added it to the current comets list.

Unfortunately, some errant data has appeared in the SkyTools automated comet data delivery system that is causing problems with the magnitude and positions reported. The Minor Planet Center has been struggling to keep their comet data up to date for some time, which has required me to supplement their data from other sources. I am not yet certain what the source of the poor data was. This is something I had not anticipated, so there is no simple means for the automated system to update the orbital elements. As a result, you will need to perform some manual maintenance on your comet database to ensure that the position, magnitude and coma diameters in SkyTools are accurate. Instructions:

1. Delete 156P from every observing list it appears in. Do see which lists it is in use the Target List tab of the Object Info (for 156P).

2. Open your Comet Database via the Data menu.

3. Enter 156 in the Num on the top right and press Enter to find the data for 156P. Or scroll down to find it. 

4. If the main (top) selection for 156P is not bolded, right-click on it a delete all of the elements. If it is bolded, open the tree to see the individual element sets. Right-click on each of the ones that are dates 2020 October or later and delete them.

5. Close the Comet Database dialog, accepting your changes.

6. Select Subscriptions from the Setup menu, ensure the box next to current comets is checked, and click update now.

7. Check your current comets list in the Target Selection Tool, with the date set for October 11. The magnitude should be approximately 11.8 and the coma diameter should be 3'.]]>

It looks like a good target for imaging with a camera & star tracker. This is a beautiful region of the sky.

There is a lot going on with comets this month, requiring a mid-month current comets list update.  

Comet C/2019 Y4 (ATLAS) has fragmented, which means it has become fainter and is not likely to become the bright comet that we had hoped for.

I have added 2020 F8 (SWAN) to the list.

The MPC is having trouble keeping their comet database up to date, so I have updated orbits via orbital elements as needed via JPL data.]]>
