On February 18, 2021 I used my SDR# (Software Defined Radio) software to pick up the Perseverance orbiter radio beacon signal when the Perseverance lander was landing on Mars. As a HAM radio operator, I have do have some experience in SDR, as I usually use it to pick up and record NOAA weather satellite signals, decode them, and then generate weather images. Here is the signal as recorded live. http://tek1systems.com/vid/MarsPerseveranceOrbiter/VID20210218_132426.mp4
I intend to capture images of these celestial targets early this year:
M97 – Owl nebula. I have many images of this; but the images are always faint with not enough exposure time. I will image this without filters first, which might produce grainy images from the light pollution – I will experiment. Filtered OIII images will follow.
NGC7293 – Helix nebula. I have never imaged this visually or photographically.
Known as the “little dumbbell” in Perseus. 26-120second light images. Cropped. DSS and GIMP stripped out the color for unknown reasons. No darks. Canon T7 DSLR, Optolong L-Pro. Meade LXD SN-10, Skywatcher EQ6 mount unguided.
Region of Pegasus. More data is needed for the galaxies as they are quite faint. All images are 20-40sec light frames @ ISO400, 10 dark frames. Filter: Optolong L-Pro. Canon T7 DSLR. Telescope: Meade Schmidt-Newtonian 10″. Skywatcher EQ6-r mount, unguided.
Stacked 37 90-second images, one dark frame with ISO400 DSLR. No filters, Canon T7. Meade LXD sn-10 on Skywatcher EQ6-r. Orion autoguider with PHD. Flat frames will make it better. Stacked with Deep Sky Stacker and edited with Gimp.
Bortle 7 sky. I have been using the Optolong L-Pro lately but I wanted to see results with an unfiltered optic train. No filter tonight. 10″ Schmidt-Netwonian. I am finding out the hard way that I need to start using flat frames to prevent vignette.
I have been digging out old images and re-editing them. This image was captured via Observing with NASA – a public education site in which one can send schedules to robotic telescopes in Arizona and obtain selected images via email. This is a project in collaboration with Harvard University and is part of the MicroObservatory Robotic Observatory Network. This is used in primary education. I have used it in the past.
Here is an old image of the Crab Nebula from ten years ago that I have edited in GIMP.
