Part of a Heart

Recommended Posts

Hi all,

This is 6 hours (30 x 12 min), taken with my modded Nikon D7000 @iso200 and Astronomik 12 nm Ha 2" filter on Meade LX200-ACF with reducer (=1600 mm FL @ F8). Guided with NexGuide on HEQ5 Pro.

The plan was to do a Ha O3 bicolour on this target, but the O3 may be a future thing due to weather conditions.
I usually remove the stars during part of my processing workflow and put them back later on, but this time I think the nebulosity and dust came out best without them. I did however try to find out which stars belong to Melotte 15 and include only those, just to portrait the Melotte 15 without anything between it and us, but I could not find that info.
Processed with DSS, Starnet and PS.

I really like starless images when it helps you to appreciate the structure of the nebula.

Thanks for sharing.

Very nice and detailed starless version. Agree with you, some stars will complete it.

As an open cluster I suppose will be difficult to say which star belong to mel15.  Maybe an arbitrary choice based on your eye?

      Hi All,
      Having had to move to an apartment where I could not use my CPC 1100, I decided that I have to see what I could do with my NexStar SLT 102 (alt-az achromatic 102mm f6.47 refractor). Setting up on my narrow balcony was challenging and the altitude bearing was so loose that it almost moved from the weight of the Canon 700D. I could not see M31 in the estimated 3.5 magnitude sky so I did a two star alignment and used the live-view to focus on a bright star. I then took a 15 second exposure after slewing to M31 which allowed me to see that I had it in the field of view. After a few more 15 second exposures and playing with the motion controls I managed to get it centered. The resulting picture is from 39 subs of 30 seconds at ISO 1600, 9 flats. The images were stacked and stretched with Siril and then I played with the curves on Gimp, cropped and scaled. Not too unhappy.

      Just thought i'll bring this up as a point of discussion. Today, cooled CMOS Astro Cameras are available in plenty. QHY, ZWO and other variants of the same camera are selling for very reasonable prices. However, there was a point of time when astrophotographers used to cool down their DSLR's as a cheap OSC alternative to CCD cameras. Give a choice, I would've purchased a dedicated CMOS OSC which can cool to 40 C below ambient, but since I had a Canon 500D which I had self modded, I requested a friend Kaustav Chatterjee (an avid model railroader) to cold mod my 500D (he had cold modded his 1000D long back). This newly modded camera has a TEC12703 single peltier and cools to approximately 20 below ambient.What do you guys think?

      I was looking to get into astrophotography with my 10 inch dobson and for start would like to buy something affordable. Cameras can be used or new. Thanks in advance!

      We are running a session at my local society on transits and occultations. One station will focus on exoplanet transits, and we'd like to build a very simple model to demonstrate this. We have a star (light source) and an orbiting "planet" but I need to work out how to detect the changes in light intensity and display this on a laptop, like a classical transit photometry trace below (taken from https://heasarc.gsfc.nasa.gov/docs/tess/primary-science.html).
      Is there a way to take a feed from a DSLR through the USB output to do this, else I could get an adapter for my ZWO and put an EOS lens on the front of that. I really do want a light intensity vs time trace in real time on the laptop. This model will be run in a darkened room.
      Thanks for any comments.

      Hiya, have absolutely no idea where to begin finding a camera for Astrophotography. And by that I mean - I know I want a canon but am unsure which to buy. It will be a second hand one. Does it need to be full frame ? Can any and all models be modified ? Is a higher pixel count the way to go ? What are the important things to look for in a DSLR ?
      any help would be great.
      Thanks
      Neil
