David...nice work on Hickson 44....transparency had to be ok for that image to happen. Star shapes held up using the .5 FR...that is good to know it can happen 

 

This is summer I hope to capture  at least half the Hickson group. Will Have to experiment with what FR is most effective

Here's some from this past weekend.

 

Celestron Edge 11
CGX EQ Mount
ASI183 Color Pro
ASI294 Color Pro
ASI290 Color Pro
Mallincam DS10
Mallincam Xterminator
Mallincam x.50 & x.70 reducers
PHD2 Guided with Orion Starshoot
SharpCap 3.2
40" Panasonic Plasma TV with active shutter 3D glasses (absolute astonishing views with that setup)

 

All of these were with the ASI294 Pro Color, f/10 (except M81, which was f/7) cooled to -27, binning 2, 10+ frames at 20-35 second exposures, gain at 460 or so, low brightness, no darks or flats, no post-processing, white balanced in the measuring histogram. The moon was casting a teal patina onto everything, and so even with balanced colors I had to adjust them in the histogram as the frames stacked. These were all cropped and gamma adjusted to match my Plasma TV view.

This is a really impressive set of quick galaxy images, and I think they are super.  You must have had a lot of fun doing them.

Thank you. It is so fun capturing these beauties. I'm always out and about in dark places in mountains or deserts with my setup, and so there's an added component of just being out and away from everything under beautiful skies, camping and staying up way late and bringing things like this into view. I'm very experienced with CCD cameras, and switching to CMOS and software to run the cameras changed everything. I used to have good images in 30 seconds with CCDs, but nothing like these, and these are only 3-7 minutes to that quality. It's well worth the wait. And on the 40" plasma TV in 3D? It's staggering. You have to see it in person to believe it.

Well, last night was the first night in about 2 weeks, because of the ongoing rain showers that plagued the northeast for god knows how long. I ran into a strange problem. For the life of me, I could not get my ASI290MM to stack, where as I replaced it with my ASI294MC and it stacked nicely. The Moon was full and there was high thin clouds and ground level fog. Still, the 290MM would not stack. So, frustrated, I took off the 290MM and put in the 294MC and my stacks went smoothly. Here are my pics. Processing done on the fly, black, mid and white levels adjustments, along with color saturation, Unsharp Masking and a touch of Bilateral noise reduction, along with Sigma Clipping.

Tuesday night was absolutely perfect! Transparency was superb. Seeing was average, but I wasn't doing planetary imaging. Temps were in the 40's, low humidity, air was absolutely dry. No need for my dew heater controller.

 

Moon was on the rise, but did not interfere with my EAA in and around Ursa Major. Some small patches of clouds rolled through, but did not impinge on my imaging. Had some early problem with my ZEQ25 mount leveling, but got it settled after an hour. My first image, M104, was done at F/10, then I realized my mistake and add the 2" GSO 0.5 reducer to my ASI294MC camera.

All processing was done on the fly. Black, mid, and white level, color saturation, histogram stretch, binning, gain, etc. I used Unsharp Masking to achieve fairly sharp images. Sigma Clipping was used, tried Bilateral Noise Reduction, but did not see a marked improvement. I only used Microsoft Paint to reduce the images and convert to JPG with annotations.

Nice captures. 

 

Last time out, I used a similar config (ASI294MC, C8, 0.63 reducer, 0.75 sec/px). I used no binning, i.e. 1x1. I got some tracking errors from the 30 second exposure times I needed. My mount was polar aligned coarsely using the PA scope and I was not guiding, so 30 sec is really a stretch. 

 

Then I had a duh moment and realized I could probably use 2x2 binning (1.5 sec/px) and cut my exposure times to 8 sec or thereabouts! Which is what you figured out, too. 

 

Are you satisfied with the resolution with 2x2 binning?

Captured during an abbreviated session from within the Flagstaff city limits.

 

Camera:  ASI294MC (cooling off), gain 395

Exposure:  30 sec, unguided

OTA:  C8 with 0.63 reducer

Scale:  0.75 sec/px

Capture software:  SharpCap 3.2 Pro

Mount:  Orion Sirius, roughly polar aligned using PA scope

GoTo Alignment:  StarSense for SW

Images:  captured as viewed, downsampled x2 and converted to JPG in PS

 

Tracking errors are evident in the captures.  So is camera noise (next time I will remember to pack the DC cable for the cooler).  Next time I will also use 2x2 binning to reduce the exposure time.

 

M51, Whirlpool galaxy, 6 frames = 3 minutes total

M64, Black Eye galaxy, 6 frames = 3 minutes total

I am all over the place with binning. I usually start out at 4x4 for framing purposes, then I go to 2x2 or 1x1 to get in closer, with the zoom feature. For wide field shots, I use 4x4 and zoom, for small objects like planetary nebula and galaxies, I tend to use 2x2 or 1x1.

Hi very much a beginner in all things imaging. Ive been doing EAA for a few months, but sporadic as weather has been bad, and have had some OTA problems!

 

Taken 28th May 19

ES 102CF, AZEQ6, ASI 294 cooled to 0 degC, Darks, no flats or bias. Native FL

Live stack 38Subs, Total 570s: basic stretch in Sharpcap, no Post Processing.

 

Thanks for looking.

Went out last night after a week or so of clouds and rain. I was eager to try out my newly acquired Meade 2080 MCOG ota. It originally came with a fork mount, but I de-forked it and added a dovetail bar and Rigel Quik finder. Needless to say, after a minor tweak to collimation, it performed admirably! The sky was clear, Moonless, very dry, no hint of dew whatsoever. Transparency was average and seeing was below average. NELM was around 5.

iOptron ZEQ25

I used on the fly adjustments:

Bilateral Noise Reduction

Sigma Clipping

Histogram Stretch

Brightness = 35

 

I captured some nice images of galaxies in Ursa Major/Leo Minor. Here they are:

Love the close up and high resolution - the Pillars of Creation is superb. Assuming this was using the ASI224 on the Orion Atlas Pro?

Yup, 224mc and atlas pro. I personally love this setup. Last night I had some tracking issues and nothing did right.

underwhelming isn't it? This was 640 seconds

I can see it. Helix Nebula is a large object. A faster focal ratio is going to be needed.

 

I have used 0.63 and 0.5 focal reducers together without much problems with the C9.25. I put the 0.63 reducer at the telescope, then adapter, and use Orion extension tube.

 

Then I put the 0.5 reducer close to the camera. For me, it is around f/2.8 to f/2.9.

 

There is going to vignetting and coma, but the trade off is shorter exposures, wider views, and less tracking problems.

I was having issues with sharpcap. But you know....its has potential. I want to try it again. Hopefully I will get clear skies soon.
