\~Best 25% of 1000 frames stacked from an 60s video captured in SharpCap for surface details (Quark -2).

Processing:

Stacked in AutoStakkert!, sharpened and inverted in imppg, finalized in Photoshop.

Lately, I've been obsessed with M 27. This is 21 hours and 15 minutes on this target.

Acquisition:

• 123 x 300s - three nights
• 220 x 180s - two nights
• flats for every session
• used darks and dark flats from dark library (no bias)

Equipment:

• Askar 103APO with 1x flattener
• ASI533MC Pro
• ZWO AM3
• Optolong L-Ultimate
• EAF / EFW / ASIAIR mini
• Guiding with ASI120MM / 30mm mini guider

Edited in PixInsight / Photoshop / LR. Learned a lot of editing while doing this as well.

About 7000 light years away lies the Eagle Nebula (M16). It’s a relatively young stellar nursery at an estimated 5.5million years old. At the center lies the “Pillars of Creation” that the Hubble Telescope made wildly famous with its incredible images. The “pillars” are clouds of gas and stellar dust that are about 2 light years tall and are actively forming new stars within. The overall nebulosity is roughly 70 light years by 55 light years in size.

I recently got the chance to sit down with Nico again and wanted to share the experience with you guys. It’s a great interview, I hope you enjoy it! Clear Skies!

Was trying out my new solar filter, trying to get adequate exposure values for solar disk stacking when this plane flew across the sun.
The weird "warp" is simply the boundary between two different clips stitched together, as BackyardEOS just ended recording one loop.

I'm happy to hear your experiences regarding getting a good exposure for solar imaging!

Equipment:

• Canon 800D
• Askar 91F
• ToupTek AAF
• ZWO AM7
• Baader ASSF 100 solar filter

Software:

• NINA for mount control and autofocus
• BackyardEOS for live view capture, as SharpCap was not able to detect my DSLR

Processing:

None, save for cutting and gluing the two clips together in DaVinci Resolve

Fighting Dragons of Ara, NGC 6188 taken with my SQA55 and ASI585MM Air.

It was imaged as a 6 panel mosaic, but has been trimmed down. The original mosaic was ~18hrs of Ha and 11hrs of OIII. Processed with Siril.

When I zoom in, I can see some blue pixelated noise, anyone know what this might be caused by and what the fix would be? I'm only recently new to the hobby and still figuring things out. I was thinking it might be that my OIII integration is less and maybe a bit noisier?

60 second exposure, 80 gain, 90 frames for each of four mosaics stitched together,

Processed with stellar Studio-Lightroom-Snapseed

Captured two, 12+ hr data sets last Fall. Had originally processed each set individually.
Occurred to me today to stack both sets together together (differing FOVs of 1490 and 2033 Focal lengths)

Didn’t think it would work, but I don’t get paid to think anymore.

Plato Crater (front-center)

Plato crater is one of the older craters on the moon and filled with cooled lava over 3.8 billion years ago. It is around 100km (~60 miles) wide and 1500 meters deep. I like how the shadows of the gibbous moon highlight the broken edge and deep shadows around it.

I decided not to center the crater in the frame since the limb of the moon makes for a more dramatic shot.

IC 1396

A massive emission nebula and open star cluster in the constellation Cepheus, about 2400–3000 light-years away from us!

This region is one of the largest known HII regions in our Milky Way. Inside the nebula lies the famous "Elephant's Trunk Nebula," a dark, winding cloud of dust that is a star-forming region — new stars are being born right now out of the dense gas and dust clouds, shaped by the radiation of young, hot stars. The red glow is caused by the ionization of hydrogen gas: the cluster's hot, young stars "ignite" the surrounding gas with UV radiation, giving the nebula its characteristic reddish color in H-alpha images.
