IC 1805 / IC1795 The Heart and Fish Head Nebula

#1

Post by Juno16 »

Hi Everyone,

My last of three data sets from the weekend before last. I only imaged this target once before and managed only a shot of the center with the ES ED102. This scope/camera combination was able to frame the target much better.

Imaged the evenings of 9/23/21 and 9/24/21 during a 95% and 90% moon.

Sharpstar 61 EDPHII with Sharpstar 0.8 FR/FF
183 light frames at 120 seconds. About 6 hours total integration.
ASI533 MC-P with Optolong L-eNhance filter. Gain 104, temperature -10C.

I shot the Elephant's Trunk nebula at the start of each evening, then switched to this target. The 95% and 90% moon over the two nights did have some impact on this image. I was able to collect some nice data on the Elephant's Trunk at the beginning of each night before the moon rose, but the Heart could not escape!

Thanks a bunch for looking and please offer any thoughts, comments or critiques!

Very nice Jim. I am not seeing a lot of negative impact from the Moon. I like the coloring and detail.

Thinking about trying this one myself a little later in the year - It'll be a two-panel mosaic for my gear.

Great image, good details and nice composition. You could maybe remove a few star, it might make it even sharper then it is now.
Thanks for sharing.

I can only think that the L-eNhance is what allowed a decent image despite the moon.

The Sharpstar has been such a joy to use. Super easy, light compact, with tight cabling and never have to worry about it running into a tripod leg! It allows a somewhat wide-field with my small fov camera.

Thanks Bob!

I will try that Kenneth, thanks for the nice comments and suggestion.

Just to share something basic that I recently learned. I noticed an issue early on with this scope when using the PI MorphologicalTransformation for star reduction. When I got the stars reduced, the smaller dimmer stars started looking like they were connecting (like small lines). Could be related to the high imaging scale with this scope/camera. It was a horribly distasteful effect. With this image, I tried reducing the Amount to a very low value (like 0.1) and using several iterations (7-10) and the reduction was much more delicate and I did not get the "lining" issue at all. Easy simple stuff.

Thanks!
Jim

Thanks a bunch “G” and Marshall.
This data just kind came together really easy. Not much change the color at all.
Really didn’t have to work very hard on the process.
The culmination third data set of probably the best weekend I’ve ever had imaging. Three imaging and data sets in four nights. Doesn’t happen often but I’m glad I could take advantage of it even with them blasting moon

Much appreciated Henk. I really enjoy my AVX. Keep everything lubed and tight and it does the job well (well enough for me!)
The L-eNhance is magic. I almost didn’t want to image with the super bright moon. The filter did wonderfully. Thanks
